Poker Night Foursome: Sorority Sisters Do Everything Together

My stepsister and I do everything together, so we have to join the same sorority. We have almost passed all the tests, but now we have to earn our spot by winning at strip poker. The only problem is that neither of us knows how to play! Luckily, our stepbrother is an expert, and as long as we find a third hot chick to join us, he'll teach us everything he knows. We know that letting him see us naked is a little taboo, but isn't college all about getting a little bit crazy? Besides, we won't enter the sorority if we don't put on a show. What could be better or sexier than a foursome with our stepbrother? Poor guy won't last a second without a boner, but we'll take care of it - all three of us. I can already taste his cum in my mouth.
