Cuddle with your sister

Shortly after your encounter with Amy, she drifts off to sleep. You and Megan are cuddled up beneath her blanket on her bed watching a movie. You stay like this for a while, enjoying holding each other. Then Megan breaks the silence with an idea. “Let’s put in a different movie.” “What kind of movie?” you ask. “A porn, and then we can do exactly what they do in the movie.” She says. Hmm, now there’s an idea. They do some freaky stuff in porn movies. Megan crawls out of bed, still naked, and you watch her ass shake as she walks over to the TV and pops one in. Your already hard at the thought of it all. The movie starts out slow, the guy on TV eats the girls out, so you spread your sister’s legs and begin darting your tongue in and out of her slot. She moans and even says the exact same lines the girl on the movie says, at the exact same time. You get the feeling she’s seen this one a couple times before. But it doesn’t hit you yet that she put it in for a reason. The girl on screen switches to giving head, so your sister kneels below you and starts working over your raging hardon. She pauses every now and then to look you in the eyes, before going back to her duty. The girl on the screen moves to riding the man backwards, so Megan spins around, back facing you, as you lay there on her bed, and lowers herself down on your cock. It’s all you can do to keep from coming right now. Your sister rocks up and down on you, trying to make you cum, but you want to see where this movie takes it. After a short while, the girl on screen spins around and rides the male character. Megan, being the wonderful sister she is, does the same, not even letting your cock slip out of her pussy. She rides you hard, staring into your eyes the whole time, until you raise up to suck on her beautiful mounds just like the movie. You are about to blow and fixing to warn Megan when you hear her say “Cum in me.” In unison with the girl on the tape. Megan had set you up, and your sister was now asking you to cum in her. You are helpless beneath her, her legs are wrapped under you and she is driving herself down on you hard, wanting it, needing it to fill her hot pussy. Breaking from the tape, “Are you on the pill?” you ask, trying to knock some sense into her. She lies, knowing it’s the only way that you will cum in her, “Yes, of course I am.” You still aren’t sure about this, but she’s got a **** grip on your cock with those legs of her, thrusting down on it, begging to be filled with your seed.
