Why is the aspiring teacher Obana-sensei staying at home… Suddenly, Mr. Obana, who had a faint love, became my sister-in-law and started living together! A cute and smart teacher at school, and a dried fish woman drinking beer after bathing at home! The unconscious temptation of flashing buttocks and breasts in bright pajamas! Full erection in a completely different look from school days! Whisper into my ear & masturbating while being watched, secret SEX in the living room, encouraging fucking, vaginal cum shooting SEX wrapping your sister! I don't want this life to end…
