REVEALED! Full insemination for the horny stepsisters!

Ok, that was really intense! My stepfather wanted to fuck me good. We waited until everyone was out of the house! Then we started, I took his hot cock in my mouth and then he unpacked the rubber and wanted to stick his thick cock in my really wet pussy! But all of a sudden my stepsister came in and caught us! She was totally shocked! But the sight must have made her pretty horny because she said „Only losers fuck with a rubber!“ and we were both on his cock. And of course we fucked without a rubber 😉 What do you think, is my stepsister right?
