[Ryuu no Yadorigitei (Zephid)] Rin-chan wants your attention (Touhou Project)

Neglected for an entire week, Rin Satsuki takes matters into her own hands by slipping into Eirin Sensei's bed and smothering him with her enormous breasts before he's even awake. Sleepy payback melts into eager surrender as she offers those soft boobs up for paizuri, moans through a long, sloppy licking, and begs to be stuffed full—Eirin's medicine apparently working far too well—until a thick nakadashi leaves her dripping and thoroughly satisfied. In the cozy aftermath, Eirin gently reminds her she only had to ask, though Rin makes it plain she intends to sulk whenever his attention wanders anywhere but her.
