[mo] Y-kun (updated 09/07/2026) {partial clean up ver}

Y-kun’s apparently innocent visit to Aizawa Nanako’s apartment, greeted with a cheerful homecoming and promises of sweets, unfolds into a teacher-student conspiracy built around Nanako’s heavy breasts, Y-kun’s oversized penis, and a growing circle of women eager to indulge him. Akiko, Satou, and the others push a recorded group encounter from flirtation into a humiliating lesson in obedience, with a remote-linked device, jealousy, and Y-kun’s embarrassment exposing buried family tensions. The final bedroom tangle leaves the participants spent and intertwined as talk of pregnancy, possessiveness, and Y-kun moving in turns their kinky private arrangement into something disturbingly domestic.
