SSIS-835 Missed the train and stayed at a colleague's house for 1 night and that was the end

When I was a student, my brother took her (Aika) to her parents' house and had sex in the next room. She's cute, sexy, and has big breasts... I was jealous of my brother for having such an amazing girlfriend. If you tell me that you are going to Tokyo on a business trip, I will let you stay here. Aika-san, who met again after a long time, felt confused by her braless, unprotected appearance. Having sex with my brother who comes home late from his part-time job... It's so attractive it's a waste! Aika was disappointed as she pushed down impulsively.
