Ayaka, the younger sister of the girl who lives with her, comes to visit her room every day. She's a popular girl at school who is also a model. She shows me her thighs and shows me her panties... Is she seducing me? One day, I was lusting after my sleeping stepsister's careless appearance, and I ended up masturbating while watching her... The next day, Ayaka smelled the thick scent of my semen and asked me to have sex with her. I had to say no, but I can't stand it when she shows me her tits like this... It was supposed to be a one-time fuck... But I was going to drown in the swamp of pleasure...
