Nobody noticed what happened underwater. Tomiko's soft hand had instinctively wrapped around my thick cock for those few forbidden seconds in complete secrecy.
As she tried to regain balance, Tomiko slipped again and fell forward — straight into my arms. Her completely naked, wet body pressed flush against mine. Her large, soft breasts squished heavily against my chest, her stiff nipples dragging across my skin.
At the same time, my rock-hard cock slid between her warm thighs and poked firmly against her lower belly, the swollen head nestling right between her slick pussy lips.
I gasped. "Hmm… Oba-san… I'm sorry…"
Tomiko's eyes flew wide open in utter shock and humiliation. She could feel every throbbing inch of my thick cock pressed intimately between her thighs — hot, heavy, and pulsing against her most private area. A tiny, involuntary whimper escaped her lips as her pussy lips kissed the underside of my shaft.
