[Flicker10 (Kuronyan)] Just Because I Sat On The Priority Seat {Doujins.com}

Pregnant high schooler Kokubu Kaho has one big frustration: her boyfriend—the shy boy five years her junior who fathered her baby—has gone lukewarm on her since the bump started showing. When he innocently claims the priority seat on a nearly empty train, her pent-up need boils over into a squelching ambush that leaves him teary-faced and buried against her enormous breasts before she drags him back to her empty family home. Once she has him alone in her room, Kaho takes full command, riding her blushing, overwhelmed boyfriend with her heavy belly bouncing until all he can do is hold on—left wondering, as his profile teases, whether he can ever lead a happy life after this.
