Marvolo keeps to his word, praising softly when Harry responds the way his husband prefers. The bedding gentles from there, less a desperate lunge towards completion as Marvolo takes without any sharpness now. He plays instead -- teasing nipples, biting rings of marks, sucking lovemarks onto Harry’s stretched out neck. When they orgasm together, one release triggering the other due to the potion, Harry feels almost normal again save an abnormal sense of fullness. Like the satiation fills his belly as well.
