When I'm out with my stepsister, I can be sure that something cool or unusual will always happen. Most of the time it has something to do with cocks or sperm. And that's how it was today. We were in Malle for vacation and were looking for the way from the beach to the parking lot. Somehow we drifted off and came to a cabin where we foolishly caught a guy jerking off in the pool. Of course we immediately went to the pool, where I immediately took this plump stand deep in my mouth. My god, how horny the sight of this boner makes me. Full of lust and devotion I blow this hard waxed cock. My stepsister was waiting at the other end of the pool and couldn't wait to suck that cock as well. We pushed that thick cock back and forth in the pool. Where would he squirt first? With me or with my stepsister? Or do we find a solution that we can both be happy? I love our new game: Tail Ping Pong
