Engrave a sex driven solely by the instinct to pursue pleasure on Sakurae's body... It is a sex that pursues only pure pleasure, like copulation. Forgetting even to wipe away sweat, they suck each other's mouths and stimulate each other's genitals. Then, with fierce piston-like thrusts that strike her hips, her reason collapses. After that, words are no longer necessary. The sound of flesh hitting flesh, the heavy breathing of two people, and the escaping moans are all that prove they have fallen into pleasure.
