I usually do my exercise laps in the pool during the day, the pool water is warmer then. Plus my son loves to strip down naked and join me after riding the hot school bus home from school. I’m already naked and working on my laps but I always am up for a interruption. As my son swims over he usually starts getting cock all ready for his tight mommy pussy. Today as he swam up with his prick stiff as fuck and ready to slip into my gash he asked me if it was okay if some of his friends came over to swim too. I told him absolutely and just then a whole group of horny little brats opened the sliding door and file onto the deck striping off their clothes and jumping canon ball style into the pool with my son and I. Those peckers were all over me, grabbing my tits , tugging at my ass , and slapping their schlongs on my inner thighs and ass cheeks. I told them they needed to wait their turn first they had to watch how to please me the right way .So I grabbed my son and wrapped my legs around him letting my slit find the right place on the tip of his cock and then I lowered myself down impaling my gash with his boner. It felt so fucking good sliding in and out of my pussy walls I was instantly coating his junk with my creamy slick juices and bobbing up and down with my titties in his face. He started sucking my nipples and spanking my ass. I looked over and our whole audience was waist deep in the pool jerking their peckers mouths wide open. I giggled and my son took the cue and started fucking me harder and as I threw my head back in my climax he groaned and yelled “oh mommy,l I love fucking my mommys tight cunt’ . I smiled and hopped off his pecker a swam over to the steps and opened my legs wide and said “who’s next?”
