His girlfriend at work, his phone getting boring, his stomach getting a little rowdy; it was time to roam. He’d been staying at her house a lot recently, and he’d gotten as used to seeing her family as they’d gotten used to seeing him. So it’s with some confusion that he passes by Selene’s room and finds it slightly ajar. At this time of day, Selene has normally locked herself in her room. He’s gotten the impression she doesn’t very much like him, and she’s done nothing to dissuade him of that notion.

It’s with that thought, and a bit of morbid curiosity, that he slips her door a little more open and peers inside. It’s very girly, colorful but childish. There’s more pink in her room than he’s probably ever seen in one place. Stuffed animals and glitter, and there’s actually a banner up that says happy birthday. Selene’s birthday was months ago, so he tries not to think about that very much. What he does think about is her bed. Soft and comfy looking, its use as a sleeping hold isn’t exactly what catches his eyes. Even with several different princesses printed on it, the shortstack on top of it all draws him like nothing else ever could. She’s cute when she’s docile and not giving him a glare. Her eyes are a little narrow, and work well to scare him off, but those eyes are stuck on her handheld game right now and don’t even seem to notice him. Unlike her tall sister, Selene’s barely four feet, and it shows. Where he’s used to long legs kicking excitedly at the most slightly enthusiastic thing, Selene slowly shifts one leg up while the other falls down behind her, not caring that when one short heel prods her bouncy ass, the other plods toe first into some pretty girl’s dress on the blanket’s image.

More importantly, Selene doesn’t seem to realize that each lift of one leg and plop of another, leaves her bare ass very visible to him. She’s got a miniskirt on, one that sparkles a little in the little light given from the window and her game. Pink and colorful and bedazzled, it barely protects her bare thighs and even barer behind from his gaze. She’s not wearing panties, not even the slightest covering. A top that hugs her stacked chest, a pair of rainbow leggings that go up to her knees, she even has her blonde hair tied back like she’s about ready to go somewhere and is just taking a break. Nothing to protect her nethers, not from him, not from the environment, not from strangers. The thought stills his blood a little, but not as much as it lifts his pants. Pants that struggle against him as he approaches the bed. “Selene?” He questions her, making sure she knows he’s here. He gives her a second, before accepting her nod as approval of his presence and slapping a hand on her ass so hard she cries out in surprise. It’s not innocent, it couldn’t be taken as innocent. He expects her to kick him and to have to make some joke to distract from how much he enjoys her jiggling ass cheeks and his bare red handprint on her. She doesn’t.

She doesn’t even pause her game. So he does what a brother in kinda but not really law would do, he climbs up on the bed, he palms both ass cheeks, and he rubs them together. He squeezes them in his palms, he digs his fingers in, he relishes the way they roll. His girlfriend is flat in both ways, lengthy but too agile and nimble to really possess the kind of curves a man needs in his life. They have a really good relationship, and his girlfriend’s the kind of odd sort he’s not really sure she’d mind this indiscretion…

It’s that thought which has him pulling off his belt. “Do you mind if I get more comfortable?”
“Sure.” She says back softly, responding to him immediately and filling him with vigor. Maybe this is something his girlfriend asked of her? Tease him in and have fun? Or, maybe he’s doing something terrible right now. Both thoughts only get him harder, as he kicks his pants and boxers off the bed. He lets his dick slap against her ass, and he slips it between the crack between two thick playthings. He grinds her cheeks against his length, savoring the feeling of joy she brings him without a care in the world. He questions if he should go further, or if he should be happy with this. It’s so nice to feel himself squeezed like this, to take in her cutesy smells and this princess-esque room without her angry pout or glare or scolding nose twitch. His girlfriend had said she’d talk to her about getting along with him more, and showing her more of why she loves him…

It’s the lift of Selene’s ass that really makes the decision for him. No longer content to rest against her with her in a perfectly breedable position, he pulls back just enough for his cock head to glide down her bottom and press against her entrance. “Oh yes.” He gasps, warning her in the least explicit way possible, before he’s pushing into tight folds that part just for him. He’s like ninety nine percent sure Selene’s a virgin, so entering her forbidden depths is a treasure he holds dear. One rock against her entrance, two against her first folds, three into her and soon enough he’s got a third of his cock into her neglected pussy. 

“Oh~” He hears her gasp in recognition, and that’s all he needs before those palms spank down on that jumpy ass. He uses her surprise, her jump, and her tightening depths to push in and hilt himself deep into her core. She throbs around him, caressing his length from all sides while spasming in shock. “What’s your um, favorite type of RPG boss?” She asks, as if nothing is happening. Even as he twitches inside of her, dangerously close to letting loose a flurry of seed into her unprotected depths. 

That’s enough to get him pumping her hard, fast, relentlessly jackhammering into her core. His tip expanding, he cares enough to answer. “The secret boss.” He explains in between heavy pants. “It’s nice to work towards something even after you feel complete- ooh fuck! Gonna!”

“Thank you.” She nods at his answer without even acknowledging his warning, smiling brightly at the thought, even as a typhoon of cum starts to jet from his tip and spearhead its way deep inside of her. He ruts quickly, draining himself full force into the small girl, joyfully palming her ass once more, albeit this time to pull himself out with a wet shlorp.

It’s with awe that he watches her stretched insides pour out a river of white cream. It flows down her lower lips, and onto the sheets below. “Glad you wanted me to share.” Is all he says as he gets off the bed, and slips his pants on. Their mother probably needs help with dinner, and if he’s to be honest, he’d rather not be here when Selene inevitably decides to address the new elephant in the room.
