JUFE-440 On a school trip, I was trained by a big-breasted married woman teacher and made to use a raw vibrator Ai Sayama

Terahashi, a misbehaving student who doesn't fit in with his class, gets scolded by his female teacher Ai after getting into trouble with a local delinquent on a school trip, which is the highlight of his student life. Although Terahashi shows no remorse, he happens to peek into Ai's bath. I thought Ai-sensei was just a plain old woman, but I realized that she has such huge breasts and is so sexy... Ai notices Terahashi's painfully erect cock and smiles mischievously.
