[Hanaya] I Fucking LOVE Fully-Nude Desk-Diddling! [Charles210]

A brazen senpai's secret after-school habit of grinding bare against the corner of her classroom desk gets walked in on by Asahi, a boy two grades her junior, and rather than stop she scolds him for snooping and keeps riding. Anna-senpai is completely hooked on the creaking, clattering desk, sweat-drenched and shameless as she declares corner masturbation the best, while her flustered junior gets an up-close lesson when she presses her soft chest against his back. What starts as an embarrassing interruption builds to a breathless shared finish against school furniture, leaving both of them thoroughly corrupted by the desk-diddling craze.
