[Silicon Jichou (Condessa)] Koto-chan Sensei, Kyuuin Ganbaru!

Koto-chan, a teacher with an enormous penis, pushes her limits by using a suction device and her own mouth and breasts to satisfy her cravings, then boldly attempts anal insertion while blushing with embarrassment. The narrative balances her shy hesitation with a fierce, erotic determination to explore every part of her body, creating a teasing tension that drives the story forward. This yuri doujinshi invites readers into a vivid, boundary‑pushing experience of self‑pleasure and daring sexual experimentation.
