DOCZ-003 — My Girlfriend's Sister Always Seduces Me Unconsciously With Her Exposed Breasts And No Bra, But She Sees Through My Erection And Says, "You Know It's Obvious," And Makes Me Cum Over And Over Again While Hiding It From Her With A Plank Cowgirl Position And A Blowjob.

Her sister is always without a bra. I know I shouldn't look, but I can't help but look at her... I always have an erection without anyone knowing. Then one night... something happened at her house. After having sex with her, I was resting in the living room when I ran into her sister. I was mesmerized by her big breasts without a bra, which were still too defenseless. "Hey, where have you been looking at for a while now?" That's bad! I ended up looking too much! I tried desperately to hide it, but my sister saw through me and said, "You're obviously erect, aren't you?" I was completely defeated by my sister's seduction, and she had a weakness that I could never tell her. From that day on, my days of being made to cum by my sister secretly, hiding from my girlfriend, began. I wanted to run away from my sister right now, as if she was enjoying the thrill of being found out, while she was sleeping... in the bath... but my thoughts stopped as she gave me a mewing blowjob with her tongue entangled! Her beautiful ass bounces as she rides him in a plank position, causing him to lose his sense of reason! She even lets him cum inside her raw, which she won't let her do... Ehhh! Whatever happens, happens!!
