Sex With Andrea

Looking at your sister's nude body sitting a few feet away, you decide that you were going to have sex with her. You were hesitant to announce your desire though. While so much had happened in the last 24 hours, acts that destroyed most of the boundaries you developed in life, you still couldn't comprehend that your mom would be okay filming her two children having sex. It just seemed for some reason like that was the act that would bring everyone back to reality. Still, everything the beings said has so far been true, and they didn't say you couldn't fuck your sister.

"Andrea, I want you to have sex with me." Andrea just grunted, 'Fine, where are you going to stick it?" You developed possibly the widest smile you ever have. This was going to go perfectly.

Andrea interjects before you have a chance to answer. "I haven't showered or anything yet so it'll probably be gross if you fuck my ass. If that's what you need to cum though then go for it." You tell Andrea that, considering the circumstances, you would fuck her pussy. You lay down on your bed and tell Andrea that she will be on top.

Andrea lowers her pussy onto your dick. You technically had sex last night with Cindy, but that lasted all of five seconds. This is the first time you get to truly enjoy sex. The feeling of your dick in her pussy was amazing. It was so tight, the temperature was perfect, and she took it in so deep that you could feel her pussy lips against your groin. She started slowly bouncing up and down on your cock. You look at her face; she clearly isn't enjoying this as much as you. Still, it was amazing sight to see her move her breasts bouncing with each thrust.

Your mom kept moving around each of you. She was getting some wonderful angles: the look on your face, the look on your sister's face, her pussy swallowing your cock, her breasts as they bounced around. Since the audio was on, you asked your mom a question. "So mom, what do you think of your kids fucking?" Mom smiles, "Well, I like to see my kids getting along. It's about time too that your sister started helping you cum. I hate to think about those nights you had to get yourself off when your pretty sister was only a few feet away."

You ask Andrea to bend over so that her breasts hung above your face. You grab her right breast and begin to suck on her nipple. The sensation caused Andrea to moan. You turn to the camera and antagonize your sister. "Mom, Andrea likes it when I suck her boob!" Mom just laughs, "yes baby boy, it appears that way." Andrea huffs, "I don't like it, it's gross!" Mom points the camera at Andrea's face. "Honey, this is John's video. Now you tell your little brother that you like it when he sucks on your boob." Andrea turns to John, gives a defeated sigh, and says "little brother, I like it when you suck on my boob."

That was all John could take. He began shooting his cum straight into his sister's pussy. He orgasmed louder then ever before. Andrea, not even waiting till John finished jizzing, got off his dick and collected her things. "I've gotta go to work" is all she said as she left the room. Mom turned off the video camera and sat next to her son. "I'm glad she helped you cum honey! Now you take my phone real quick and get the video. I have to get ready for the day."
