Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Anne Nony Mouse...)

When you get home, you unlock your door, and you hear them giggling and moaning in your room. You quickly strip your clothes off, your cock already hard, then you slowly open the door to the bedroom, not wanting to disturb or interrupt them (too much.)

Amy is on top, with Rachel underneath, eating her out, and your step-sister is moaning and has one hand on one of your girlfriend’s tits, and one on her own. Hearing the door, she looks up, and seeing it’s you, says, “Mmmm… Ross… this girl was made for sex! And now she’s all ours! You lucky devil! Thank you so much for sharing her with me! Oh Gawwwwd!!!”

Her capacity for speech trails off there, as Rachel must have found a really sensitive spot in your step-sister’s pussy.

This is undeniably hot, but you ain’t here to watch, but to participate! You see that your step-sister’s mouth and ass are both available, so now you just have to decide which end first.
