Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Yeetmaster64...)

Your step-sister Rachel immediately hugs your cum-covered girlfriend.

“Hey Rachel, got your invite.”

Amy is looking sexy in a sports bra and yoga pants which show a clear bulge that is growing by the second, you know you’re in for a good time.

“Mmmm I’ve been wanting to shoot a load all over my brother for the longest time! If his slutty ass doesn’t end up drenched in all of our cum I will be very disappointed. His girlfriend too. Let’s own their asses,” your step-sister says.

You and Rachel get on your knees and Ashley, Monica, and Amy all surround you and start slowly stroking their cocks. Amy smacks her cock into your face. “Ha ha Ross, I think it likes you.”

“Just wait until you use his ass,” Monica says. “It loves dick even more.”

Just then, Ashley sticks her cock in your mouth. “Yes, Ross, suck my cock and drink up all of my cum, you slut!”

Feeling left out, Rachel grabs Amy’s cock and starts sucking. “Ooh his whore girlfriend wants my cock too,” Amy says.

Monica starts stroking her cock even faster at this sight and says, “Oh my god I’m going to cum!” and sprays her load all over your and your girlfriend’s faces and her tits. The sight of this makes Ashley and Amy cum in your mouths and, as it starts to spill out of your mouth, you feel even more warm liquid hitting your chest and dick.

Amy had pulled out of Rachel’s mouth and rather than having her swallow her cum, sprayed it all over you and your girlfriend.

“Now that’s what I’m talking about,” your step-sister says.

“I love the taste of your cum, stepsis. Wish you’d done this for me sooner!” you say, eager to please.

“Alright, Ross and Rachel get on your hands and knees you sluts it’s time to use your other holes!”
