Chapter 3 - Byleth/Rhea C Support

As Byleth nervously spared glances around the tidy, expansive room Rhea welcomed her with a beatific smile “Welcome, Professor. This is the first time I have welcomed you here, is it not? There is no need to be nervous. Please, come closer. When you speak with me here in this room, you are not speaking with the archbishop, but with Rhea. It's just me.” As Byleth stepped forward she struggled to maintain her typical stoic exterior, inside she felt more nervous standing in Rhea’s own quarters than ever before. Only Sothis’s incessant reminders on the way here had tempered her enthusiasm and trepidation with the slightest bit of suspicion.
Still, in this moment, standing before the most beautiful woman she had ever seen; who had treated her with such trust and kindness, Byleth could scarcely say a thing but the simple truth “I'm still nervous.” Rhea’s kind smile became bemused as she replied “Such a sweet child.” Byleth flushed slightly at this, at once gratified and ashamed at finding such happiness in being patronized. At this Sothis appeared, her little arms folded tensely, next to Rhea with a look of exasperation. Predictably she berated Byleth “You fool! Can you not set aside your lust for even a moment?”

Rhea had taken Byleth’s apparent embarrassment as an indication of discomfort at conduct unbecoming faculty of an academy and monastery, she spoke to create a more appropriate tone for their conversation “Oh, my apologies. I should not be treating you like a child. As Jeralt's kin, somehow you don't seem at all a stranger to me... Speaking of Jeralt, may I ask if he ever spoke of me to you?” At this Byleth froze, looking to Sothis who stared intently into Byleth’s eyes, commanding her “Do not betray your father’s trust, deceive her!” Torn between loyalty to her father, contesting with her overpowering desire for Rhea to feel the same affection she felt, Byleth vacillated. Overcome with emotion she could only blurt out a useless, clumsy lie “He said you were incredible.”

Rage and bewilderment overtook Sothis’s features as she threw up her tiny hands, utterly exasperated at Byleth’s pathetic attempt at deception. A look of shock and disappointment washed over Rhea’s previously serene countenance “Hm, is that so? Unfortunately, I am unable to believe that such words fell from Jeralt's lips. I want you to know that you are free to speak candidly. There is no need to spare me from the truth, however harsh it may be. Since you are here, shall I tell you about the Jeralt that I knew?” 
A look of weary disappointment finally settled over Sothis’s features, as she talked over Rhea, giving Byleth one final piece of advice, “I see she still wishes to converse with you even as you have shown yourself to be both knave and fool. I know your heart, you ache for her more than anything, offer yourself to her. Does it not appear that nothing could have her give you the condemnation you have earned?” With that sothis vanished, leaving Byleth to hear the end of Rhea’s story, much of which she had missed.

“Jeralt jumped in front of an attack meant for me. He was gravely wounded. On the verge of death. I tended to his wounds in a desperate attempt to save his life. Thankfully, my efforts were not in vain. Jeralt managed to escape a seemingly certain death. I made arrangements for him to receive further care at Garreg Mach. The moment he was deemed fully recovered, I invited him to join the knights.” Telling a story meant to bring them closer together had returned Rhea’s radiant smile and seeing that Byleth brightened, feeling reassured by what little of the story she had heard replying “I didn't know... Thank you for telling me.” 
Rhea, kept her enchanting smile as she answered simply “Well, it is not a story I have often repeated. Even at the monastery, there are not many who know that. I tell you this because… to me, you are the child of the one who saved my life all those years ago. And also…” Seeing a possible way to understand the object of her desire Byleth tried to keep the desperation from her voice as she queried Rhea “Yes?” Rhea seemed to struggle with something. A distant look and blank expression overtook her face. Eventually the look passed and she replied, cryptic as ever 
“Never mind. It is nothing. I simply wanted to say that I trust you. By coming to visit with me today, you have... Well... Suffice it to say that my day is brighter than it otherwise would have been. I thank you for that.” 

Byleth smiled hesitantly, ignoring the unspoken truths Rhea still felt she couldn’t trust her with, she responded to Rhea “No, thank you Rhea, I don’t deserve that trust. I just lied to you yet you seem to understand. What I can’t understand is why my dad doesn’t value the way you support me, gave me the chance to teach these wonderful kids, and how you have more faith in me than anyone ever has. Whatever problems there are between you two I know it will all work out.” Rhea’s beatific smile returned at this profession of faith. 
But it faltered slightly as Byleth took a step forward and stared deeply into Rheas striking pale green eyes before continuing “I don’t deserve it but I have one more thing I’d like. You are the most beautiful woman I’ve seen and I want you.” Hoping for an enthusiastic affirmation of shared feelings but expecting a succinct rejection she instead received another cryptic, far away look. 

Byleth had little reason to assume this wasn’t Rhea trying to think of a way to let her down gently so, stifling tears she turned and quickly began to move away, only to have her hand caught by Rhea. Turning Byleth saw that the faraway look wasn’t totally absent, however a hint of her smile had returned and she said in an unusually light an airy voice “It has been so very long since I have opened my heart to another.” She then fixed Byleth with an intense gaze, finally back in the present before committing “But there is no one I would rather give myself to.” With that they both surged forward, kissing one another intensely. 
Byleth inhaled deeply of the white lily’s sweet scent which faintly pervaded wherever Rhea stood, so close to the flowers that always rested in Rhea’s hair the smell was intoxicating. With one hand she cupped the flawless skin of Rhea’s cheek and ran the other through her silky mint green hair. Rhea mirrored the way Byleth stroked her hair, but her other hand roamed lower, grasping one of Byleth’s large, perky breasts. This provoked a moan that only encouraged Rhea to kiss her more intensely. Soon Byleth pulled back from the embrace, breathless and flushed. 

Rhea immediately began to help Byleth slip out of her Teacher’s uniform who soon stood naked. She looked with a hunger at Byleth’s smooth skin, marred slightly here and there by scars from battle, and at her large breasts. She drank in the swell of Byleth’s ample hips and the way her petite tool throbbed with need. Unable to resist any longer Rhea surged forward using a hand to cup one breast as she took the nipple into her mouth while using her other to knead one of the rounded cheeks of Byleth’s rear.
Byleth gasped and squirmed under Rhea’s ministrations but eventually regained enough composure to ask “Are you going to join me?” Remembering herself Rhea looked down at her sacred vestments, connected by a thin strand of pre to Byleth, and smiled ruefully before replying “But of course, dear one.” With a wave of her hand and a shimmer of green light she stood naked which took Byleth by surprise. Rhea’s exposed form was more beautiful than Byleth had dared to dream. Her vibrant peach skin, flushed with arousal, was utterly immaculate. The full, perky breasts which protruded from her chest were rounded enticingly. 

But these attractive features paled in comparison to the narrow waist which flared to perfectly wide hips. Hips which framed a huge but still perky, rounded ass and an absolutely massive, pulsating cock. Byleth could scarcely fathom the size of the thing, even as she dropped to her knees to lap a bead of pre giving her a first taste. The flavor was faintly sweet and floral, as perfect as everything about the woman before her. Rhea sighed contentedly as Byleth experimentally licked part of huge shaft before taking the fat head into her mouth to suckle at. With very little of the huge heavenly rod in her mouth Byleth felt it press against the back of her throat, there was little chance she could ever hope to properly service something this size as she was. Even allowing a mere third of it into her mouth she could feel the strain on her jaw. 
She gave it one last suck as deep as she could, savoring the taste, before letting it slip from her mouth and switching to the use of her hands to try to satisfy the beast before her. Rhea gasped at the vigorous stroking but she could see the hints of Byleth’s frustration at not being able to have her as she wanted. Rhea took Byleth’s hands in her own, provoking a confused expression from the younger woman, and offered her a chance at what she desired “Do you trust me, dear one?” Byleth smiled and, once again gazing deeply into Rhea’s mint green eyes, gave her affirmation “More than anything.” Rhea’s beatific smile returned and her eyes glowed green as energy flowed from her into Byleth’s willing body. At first Byleth merely let out a pleased groan as a pleasant warmth suffused her hands, soon flowing into her torso.

But as the sublime heat overtook her core that groan escalated to a blissful cry that soon faded from knowing as Byleth’s perception of the world dimmed. She was a mote of satisfaction swept away in a sea of warmth and joy. She drifted through mounting waves of exultation before reaching a rapturous peak that left her giddy even as she returned to reality. As she slowly recovered from her insensate state she realized Rhea had kneeled down and was once again embracing her, now singing
“In times flow...see the glow, of flames ever burning bright…
on the swift...rivers drift, broken memories alight…” 
Hearing Rhea sing Byleth pondered the pleasant feeling of nostalgia the song elicited. It mingled with the joy of her sublime transformation and, filled with appreciation for the woman holding her, she brought her arms which had been dangling at her sides to grasp Rhea as tight as she could. Rhea tightened her embrace in response, letting out a pleased sigh as they sat on the floor, holding one another.

After a time Rhea pulled back from the embrace, again peering into Byleth’s eyes as she bore a countenance of happiness tinged with curiosity. She queried the smaller, younger woman “How do you feel? Now that you bear my crest you should find yourself more capable in all endeavors.” Byleth beamed back at her, speaking with rare excitement “I feel amazing, let me show you.” Byleth scooted back and, understanding her intention, Rhea gracefully rose to her feet. 

Confronted again with Rhea’s massive rod, Byleth now felt only anticipation. Drawing a deep breath she began taking the huge tool, first into her mouth, but quickly down her throat. Rhea let out a pleased groan as Byleth took her deeper and deeper. As her throat bulged from the intrusion she reached around Rhea’s motherly hips and grasped her plump cheeks, fingers sinking into her considerable backside, urging her to begin. 

Not able to restrain herself any longer Rhea drew back, and then gasped as she pistoned forward. Rhea’s fingers were tangled in Byleth’s silken blue hair as she held steady the smaller woman's head. Byleth encouraged Rhea by pulling and kneading the fat, round spheres of Rhea’s ass as they jiggled in response to her powerful rutting. Byleth delighted in Rhea’s divine form even as she felt Rhea’s giant balls crash again and again into her quickly reddening chin. Rhea’s pleased gasps escalated into cries as her voluptuous hips blurred with speed as she claimed Byleth’s throat.

Finally Rhea wailed blissfully as she hilted herself and began to unload deep in Byleth’s throat. At first Byleth continued to grope Rhea’s assets to heighten her release, overjoyed to finally be able to bring so much satisfaction to the object of her affection. Though it was in too deep for her to taste, the potent seed’s sweet scent, reminiscent of Rhea’s white lilies, intoxicated Byleth. As rope after rope filled Byleth she soon realized the impossible volume of this release, she already felt as though she had eaten a full meal, that she needed to breathe. All the while Rhea’s eyes were shut as her moans, gasps, and cries continued in time with her inexorable peaking. 

Leaving red marks as she finally released Rhea’s behind from her grip she pushed on Rhea’s thighs freeing herself and gasping for air as Rhea’s release continued. Byleth gasped for air and closed her eyes as Rhea began painting her face white as spurt after spurt rained down. By the time Rhea’s massive release ended Byleth found her face, hair, and ample bust covered in Rhea’s seed. Byleth wiped her eyes to free her vision, and get a taste, immediately confronted with the slick but still throbbing divine rod. 
Looking up she saw Rhea bearing a look of satisfaction tinged with embarrassment, she apologized to Byleth “It had been so very long, I have a way of giving thanks if you are not spent.” Byleth smiled as she replied “Of course! That was incredible, what’s next?” Rhea simply smiled and grasped Byleth’s hands, helping her to her feet. Byleth then gasped, surprised as the larger woman effortlessly grasped her ass and lifted her over her cock so that she could wrap her legs around Rhea’s waist. Byleth savored the feel of Rhea’s huge length sawing between the perky, rounded cheeks of her ass. The way it pressed at her entrance built an unbearable anticipation. She shared a kiss with Rhea before pulling back to look down at her angrily swollen, comparatively tiny length, begging Rhea “I need it, please.”

Rhea simply smiled reassuringly before swiftly lifting Byleth before gradually lowering her on to her thick cock. Byleth mewled as she finally found herself being completely taken. Painlessly taking a monster like the one Rhea was impaling her with should have been impossible, the way Byleth’s toned stomach stretched slightly to accommodate it attested to that. Yet as Rhea slowly slid further in, inexorably stretching her, Byleth found only a deep sense of satisfaction and building pleasure. When Rhea finally bottomed out she took a moment to admire the way Byleth writhed and clenched around her length. The way her diminutive tool had already begun to leak, painting a line of her submission down Rhea’s smooth stomach. 
Seeing this display Rhea knew Byleth was ready. She tightened her grip, sinking her fingers into Byleth’s perky ass, as she lifted Byleth and drew her own hips back. She then slammed upward with the full might of her massive rear, using her hands to slam Byleth down in tandem. Byleth could only lean forward and wrap her arms around Rhea’s back, holding on as she cried out, overcome. Rhea relentlessly plowed upward, her fat cock claiming Byleth over and over. The giant, perfectly rounded globes of Rhea’s rear shook and clenched as she slammed into Byleth relentlessly. Byleth gasped and moaned as her own dick uselessly flailed, drooling out proof of her pleasure. Rhea watched with satisfaction as Byleth found her first peak, wailing as she clenched down on the huge invader. She emptied her modest load onto Rhea’s lower stomach, it dripped down to the turgid pillar slamming into her, useful only as a lubrication to ease her own domination.

Byleth’s surrender only goaded Rhea to piston even faster. Their voluptuous figures shook and glistened with sweat as they both gasped, groaned, and cried. Rhea’s wide hips again began to blur as she rutted into Byleth again and again. Rhea’s massive nuts swung up with each thrust to repeatedly crash into Byleth’s plump rear. Though they had both begun to sweat Byleth only registered the intoxicating fragrance of Rhea’s lilies. Byleth could barely use her limbs to cling to Rhea as she moaned and gasped as the huge dick reaming her incited yet more dribbling from her bouncing member. As Byleth’s wailing grew hysterical she found her second release. Again this drove Rhea’s inhuman swiftness and power pounding the giant pillar deep into Byleth impossibly fast. Overwhelmed with pleasure and outmatched in stamina Byleth came undone, her arms failed her, she began to fall backwards. She had only fallen a few inches before Rhea’s hands left Byleth’s reddened ass and shot upwards, deftly catching Byleth’s head and resting it gently on Rhea’s shoulder. Rhea gracefully carried Byleth, who strained even to use her legs to cling to Rhea’s waist, to the bed and laid her down even as Byleth remained impaled on her fat, throbbing cock. With Byleth laid supine Rhea perched over her in a mating press but only elected to kiss her tenderly. 

Rhea pulled back and Byleth gazed up at her divine features illuminated by the sunlight filtering in through the window behind Rhea’s bed. With her headdress gone and hair out of place she still looked perfect, the exposure of her elven ears raised no questions for Byleth, she did not expect such a being to be an ordinary human. Rhea’s gazed down with affection, seeing the pure adoration in Byleth’s beautiful features. Even covered in sweat and dried cum she looked amazing to Rhea. Rhea again posed the question “If you are still not spent?” Byleth smile widened, answering through a roll of her hips, stirring the thick rod deep inside her. 

Rhea gasped and savored the feeling for a moment before pulling back before crashing down into Byleth. As Rhea’s powerful thrusts provoked now hoarse moans Byleth arched her back presenting her perky, full breasts. Rhea cupped one and took a nipple into her mouth, even as she continued relentlessly plowing her fat dick deep into the woman below her. Byleth’s ragged cries grew louder as her toes curled, her legs dangled on either side of Rhea shaking in response to the endless pounding. With every flex of Rhea’s thick, powerful thighs and ass she drove her hardness down into Byleth who’s dick now leaked onto her own stomach. Both of their voluptuous forms, a mixture of soft and hard, jiggled in response to the force of Rhea’s reaming.
Their voices were a cacophony of hoarse cries, escalating in volume as Rhea thrusted fast and hard. Overcome, Byleth came a final time, shooting thin ropes across her own tits and face and clenching at the giant rod still pounding her. This final proof of dominion and the way Byleth gripped her so tightly was enough for Rhea to finally find her second peak. Rhea drove in to her hilt, letting out an ecstatic sigh as she began to blast jet after thick jet as far into Byleth as she could. She leaned over Byleth and kissed her even as Byleth moaned at being filled so totally. Rhea pulled back as her climax finally began to subside and saw Byleth’s stupid smile and glassy eyes. Seeing they had both found satisfaction Rhea pulled out, provoking a final gasp and dribble of cum from Byleth, laying beside her as she almost immediately began to snore. 

During a particularly loud snore the door to Rhea’s chambers was opened deftly by Seteth who seeing Rhea in bed began “Lady Rhea it is highly irregular for you to be sle-” Half way through his sentence he registered the impossible, that someone was in bed with Rhea. That it was a disheveled Byleth, sleeping happily covered in sweat and dried cum, went part of the way to explaining the situation. That the Rhea walking towards him was only slightly less disheveled surprised him far more. He couldn’t help but query her as she reached the door, a smug but curious smile on his face “She handled you that well?” Rhea looked over to the sleeping Byleth with fondness as she replied “She is no ordinary human, Seteth.” Now she looked more serious as she addressed Seteth “In fact, we have much to discuss in regards to her.”
