[Kakukonoka (Menoko)] Senpai no Oppai

A feminized senpai with a plump, quivering figure and achingly sensitive nipples begs his kouhai to stick it in, offering himself up with dizzy, hungry enthusiasm. The eager boy happily obliges—first reaming that tight hole from behind, then driving him over the edge with a buzzing vibrator against his nipples, pushing the breathless, lingerie-clad beauty into a frenzy of pleasure until he's shaking apart in climax.
