[Lv.X+ (Yuzuki N Dash)] Hatsu Koi no Onee-san ni Amaetai Dake no Jinsei Datta [ArkOfLight]

A lonely bachelor reconnects with his voluptuous childhood babysitter, now a mature woman eager to rekindle their old bond. As she pins him down with her legs and whispers "Naokun... let's kiss," the boundaries between caretaker and lover dissolve into a sticky, breathless encounter soaked in mutual need. Beneath the sweetness lies a darker edge—she reminds him that he can't touch certain places, hinting at a dangerous undercurrent that threatens to swallow them both.
