4th Of July Party With A Twist

So I've got this hot new girlfriend Layla, blonde, natural pierced tits & a cute butt. I'm bringing her to a 4th of July thing & my stepmom Lolly is there. Thing is.... me and my stepmom have messed around while dad was away before. She does not have natural tits. And she won't stop showing them to me. I'm a little worried Layla will catch us, Lolly is always horny... she even comes on to my girlfriend! I wasn't prepared, especially on this day of independence... but Layla was into it! She liked my stepmom hitting on her! I dont know what to think, but things escalated quickly when my stepmom dragged me & my girlfriend to the room. They started kissing & rubbing each other, I join in...my girlfriend and stepmom share my big cock and they suck and lick it. My girlfriend rides me while her tits knock around and my stepmom assists us. They both put their big beautiful asses up for me to fuck from behind, blasting one girl while staring and touching the other. Both girls were so helpful, encouraging each other to get that dick. I make my stepmom cum one more time and then I shoot my own load in my girlfriend's open mouth before both of them share it. Happy 4th of July to the greatest nation on earth!
