Cock ping-pong. Until the double shot!

When I'm out and about with my stepsister, I can be sure that something cool or unusual will always happen. It usually has something to do with cocks or cum. And that's exactly what happened today. We were on vacation in Malle and were looking for the way from the beach to the parking lot. Somehow we drifted off and cum at a hut where we stupidly caught a guy wanking in the pool. Of course we went straight to the pool, where I immediately took this bulging boner deep into my mouth. My God, the sight of this hard-on makes me so horny. Full of lust and devotion, I blew this hard cock. My stepsister was waiting at the other end of the pool and could hardly wait to suck this cock too. We pushed this thick cock back and forth in the pool. Where would he squirt first? Me or my stepsister? Or would we find a solution that would make us both happy? I love our new game: cock ping pong
