When I was a student, my brother brought her (Aika) to his parents' house and had sex in the next room. She was cute, sexy, and had big breasts... I was jealous of my brother for having such a great girlfriend. If you had told me you were going to Tokyo on a business trip, I would have left you here. Aika-san, who had met again after a long time, felt embarrassed by her braless, unprotected appearance. Having a sex fetish with her brother who came home late from part-time work... It's a waste to be so tempting! Aika was disappointed as she pushed down impulsively.
