Just before starting to live together, I was allowed to stay at her place until the move-in day for our new home. She had a quiet older sister, Reisan. Although Reisan seemed strict, she was extremely careless at home. Without a bra, she would shake her H-cup breasts, and under her tight cami… I couldn't stop getting an erection around such a Reisan, thinking it was dangerous, when she started seducing me…!
