Why not

"Sure, you all can have some fun with me too. I want the 4 of you to share me and fuck my holes good," you say after thinking for a minute and stand with your legs spread seductively. They don't need to be asked twice, and James slides his big cock into your pussy from in front as Ethan slides into your ass from behind, both guys bottoming out inside you. You moan loudly as both your holes get filled and stretched out, and they hold you between them to support you.

"Ooo you guys are so big... fuck me hard and show me how you treat a mature kinky slut like me," you say. Your son's two friends start pounding you hard, making your body bounce up and down from their hard thrusts as Mark and Alex watch.

Then you get more than you expected as they decide to do more than watch, and your son slides his dick into your pussy next to his friend while Alex pushes his rod into your ass along with Ethan. Your mouth opens wide and your body goes limp as pure bliss overwhelms you. They all barely fit in you and your holes are so stretched right now, but soon your son and his friends get into a fast rhythm, fucking you roughly, and they start squeezing your boobs too and pinching your nipples.

Your body tenses, and you let out a loud scream as your pussy squirts hard, your love juices gushing all over the floor. They pound you even harder, sharing you between them like the filthy slut that you are. Orgasms ravage your body over and over again, making you squirt every time and moan and scream continuously, eventually making you out of breath.

"Oh yeah... I can't believe you're all inside of me... now you all need to cum in my pussy," you say barely able to speak. Mark and James both shoot a huge load into your womb, then they pull out and let Ethan and Alex deposit their warm loads in you too, all 4 guys moaning in ecstacy.

"Thanks, that was so much fun guys," you say catching your breath. "Can you guys carry me to my room? I can barely walk now because you all were so good." You giggle as you say that showing them how much you loved it. You see the floor is completely soaked with your squirt now, and you know you'll have to clean it up later but it was definitely worth it.

Mark and his friends carry you to your bed, gladly helping you. Their cum drips down your legs as they carry you, your pussy barely holding it all. You notice your stomach bulging out, and your eyes widen a little as you realize its from the huge creampies they all gave you.

"No problem, any time mom. We should definitely have more fun after school," your son says smiling before they walk back to the living room and go back to sleep.
