Description Busty lesbian teacher Ayano underwent the ritual to grow a futanari-style cock so she can fuck her girlfriend Yui. However, for the magic to work she must take in her student Kouki Morizumi's cum 90 more times, and there's only a month left until Yui's birthday! Ayano and Kouki get busy several times a day to meet the deadline: paizuri in empty classrooms after school, blowjobs on the roof at lunch, even fucking in the bathroom during class! Although Ayano tries to keep it secret, Yui notices that Ayano seems hornier lately. But Kouki is keeping secrets, too...and one of them is about Yui!
