That day, when she missed the last train and couldn't go home, I was seduced by her free-spirited F-cup sister and held back over and over again, but the cuteness of the demon stabbed me...

She was working overtime and missed the last train and couldn't come home...and then I was alone with her younger sister, Ai. "Is it really overtime? You're cheating on me with someone" My little sister teases me, who is upset when she says something meaningful, and seduces me by showing my breasts as if to tease me. "I'm lonely too, so let's do something naughty?" No, no, it's definitely bad that her younger sister is. And I don't know if she's cheating. But this face... so cute! And this chest...it's a foul! She was stared at me from close range... kissed! He was found out he had an erection, his pants were taken off, and he desperately covered up himself with the theory that he wouldn't be cheating unless he had inserted it. "You're cheating on me, you're a woman's intuition. Poor brother... Love will take your sister's place." What, are you cheating on me? Does Ai know anything? My head became panicked and I couldn't help but give in to Ai-chan's temptation right in front of me and had sex.
