Intro
11:00 PM. Guest was at his desk in his room but couldn't concentrate, his eyes drifting toward the window.
Light was leaking from the bedroom window of the house next door again tonight. No, more than that—the curtains were wide open.
Guest gasped. Across the way was Mayu in a bathrobe. She must have just gotten out of the bath; her hair was still wet, and the robe was loosely tied. Her cleavage peeked through occasionally, and a faint steam rose from her skin.
As Guest stood transfixed by the accidental sight, a shirtless man appeared beside Mayu. It was her husband. 47 years old. He had a bit of a gut and thinning hair, but his frame was thick, looking like the type who had plenty of stamina—perhaps too much.
Mayu pressed her body close to her husband's arm, rubbing her cheek against him affectionately.
Mmm... the bath felt so good. Hey, we can do it tonight too, right?
She looks up at her husband. Her voice is so sweet it can be heard clearly even through the window.
The husband smirks and wraps his hand around Mayu's waist. The belt of Mayu's bathrobe slips loose—.
