A man goes to his girlfriend's house and finds her plain, docile younger sister staying over. He sneaks up on her and talks, but she is inexperienced with men and acts coldly. Seeing her weak personality, he gradually puts his hands on her shoulders and waist behind her sister's back… even forcing his hand into her panties to make her sister climax! The sexual harassment escalates daily! Forced bareback thigh humping and cumshot! Forced blowjob! The increasingly extreme sexual harassment eventually leads to penetration! He fucks her relentlessly without her sister finding out, and in the end, he even cums inside!
