I was aroused by my cosplayer sister's sexy body and ended up having a physical relationship with her. We didn't think it was good for either of us so we kept our distance, but one day she showed up in a reverse bunny outfit with her breasts completely exposed and asked, "Hey... does it look good on me?" I knew in my head that it wasn't right, but my cock was throbbing with excitement and I couldn't hide it... I removed the nipple covers and played with and licked her nipples until they went numb. I pounded her hard and came inside her until her breasts were shaking 100 times. *This work is a sequel to "My sister is a cosplayer who wanders around the house in an erotic and outrageous breast-baring costume, so I punished her by squeezing her breasts and pounding her hard." This is an excerpt from " Yumino Rimu" (product number: dvaj00636).
