[kuroma] Pixiv's Onahole ABC series

A stern teacher with a loose tie and short skirt dominates a petrified girl trapped inside a pink onahole toy, purring that she'll keep her prisoner "until [she] ejaculated three times in a row" while drool pools at her feet. A busty blonde classmate soon squats over the squirming captive, apologizing through heavy-lidded moans as she pleasures herself with the helpless body. The scene escalates as athletic girls in uniform and sports bra alike discover and abuse the pathetic, shrinking toy, her mind shattering as she begs to simply be thrown away.
