Ren's hips snapped forward again, burying himself to the hilt inside his older sister's tight pussy, dripping heat. The old bed groaned beneath them, metal springs squealing in rhythm with Kyouka's breathless cries.
"Nnghh~Ren! You're… you're so deep!" Kyouka gasped, her nails digging into the thin mattress. Her body trembled, half from the aftershocks of cold, half from the sudden, overwhelming fullness of her little brother's cock stretching her virgin walls.
Who could've thought this would happen? Kyouka had never seen Ren as a possible sexual partner until recently, and now that same foster brother of hers was deep inside her, stretching her pussy walls.
Ren smirked against the back of her neck, teeth grazing her skin. "Took mine, huh? Cute. But who's the one getting fucked stupid right now, big sis?"
