"The kid might wake up so please hold your voice back, okay?"

Mari, an office worker in her 30s, currently has unrequited feelings for Sakurai, her kind and capable junior colleague. She got the shock of her life when she accidentally bumped into him one day with a child in tow! But he later opened up to her and explained that he actually took in his late brother's son and is raising the boy on his own now...

Out of worry, she unintentionally offered to help him out. When she went to his house, she accidentally fell asleep after playing with the kid and by the time she woke up, it was already midnight! When she touched Sakurai who was sleeping in the living room, she found herself suddenly being pushed down by him!

As her whole body gets gently caressed, her moans escape her. Though she feels embarassed by the naughty sounds echoing while she desperately tries to hold herself back, she can feel a throbbing in the back of her belly.

"Senpai, you're so cute...", when Sakurai whispers this in between their sighs, a mindnumbing pleasure begins to overwhelm her... She feels like she might go mad from being sweetly messed up by the infatuating love shown by her junior who had suddenly turned into a beast!
