I just got back from the gym and jumped in the shower. I didn't think anyone was home but was I wrong, in the middle of my shower my sister burst into the bathroom. My sister, Kay, insist that I fuck her again, I tell her I do not think it is a good idea cause everyone was supposed to be home soon. Somehow Kay convinces me and the next thing I know my huge cock is in her mouth, I didn't even get a chance to dry off before my cock was so deep inside of her pussy. Kay lets me fuck her on top of the sink before I cum inside my sister's mouth, good thing we are in the bathroom so she can spit the cum out of her mouth
