[Yayoi Fantasy Zone (Obata Yayoi)] Danshi-kou no Josou Onapet Don-chan, Ganbaru! [mysterymeat3]

Sumito—affectionately nicknamed Don-chan—has volunteered as his class representative's personal onapet, and the eager little tomgirl still has so much training ahead of him. With a vibrator strapped beneath his skirt, he learns to swallow every last drop and melts when his partner insists he's no substitute for a girl, but something far cuter and more enticing in his own right. By the time he's pinned down and filled with a continuous stream of sparks, the blushing boy is already plotting how to repay every classmate who wants to teach him something so wonderful.
