Now my stepsister's husband is getting fucked in the pool!

OMG! What have I gotten myself into again today. My boyfriend has been really horny for me for a long time. Only that my stepsister is so open and lets me fuck with him I would never have thought. And since we are all together in the pool, he immediately took the chance and fucked me. Of course I also had to eat his delicious cock. My stepsister was extremely turned on by this. She had to do a little bit with this horny bitch. My boyfriend sucked off horny and not too little. Oh man, I hope this doesn't become a habit that we fuck each other's men!
