My sister and I decided to consume one night while our parents were out of town. After a few hours, Fifi ended up getting too much to consume and had to go to the bathroom. Only working bathroom, was our brothers...oops. Fifi ended up spewing in the bathroom, but felt completely find afterwards. We were leaving the bathroom, and our brother was in his bed, watching T.V. We were both horny, and no guys came home with us...so, we decided to talk our brother into having sex with us. We promised we wouldn't tell mom or dad our dirty secret
