[300MAAN-007] [Wari-kiri] I asked a man and woman at the beach to let me give them a lotion massage for money. Yuko (21) and I are friends in the same circle, with no romantic feelings between us. Wle we were massaging each other's bodies with lotion, Yuko got turned on and we kissed. Our rationality disappeared and we ended up having unprotected sex!
