Collaborative sex stories let us write the plot together
(Her Secret Fantasy, continued by Timmip12...)
Rachel runs to the phone and rings up Amy. You hear her talking but the words are indistinguishable, so you assume she must be asking Amy for permission.
You smile and decide to jack off, thinking of all the things you’re going to do to your step-sister when she shows up. You stroke your cock, imagining Rachel grabbing Amy by the hair and forcing her down onto your rock-hard cock.
You quickly cum and frown. You’re gonna need to work on holding out longer with all the fucking you’re gonna be doing soon.
You slowly drift off into a nap, worn out, and dream of Rachel and Amy.
