The Photoshoot

You ask Andrea and mom to meet you in the living room. You tell your mom that you need her to take the pictures so you can focus on your sister. Your mom happy obliges, takes your phone, and stands behind the couch ready to start snapping some memories. As Andrea joins you, you make a request. "Hey sis, remember that dress you wore to prom? I want you to put it back on. I jerked off for like, a week straight thinking about you in that dress." Andrea muttered "gross", then went upstairs to change.

While you waited for her to come down, you take off your clothes and start masturbating. Then you ask your mom a question. "Mom, why is Andrea so mean to me when I have to cum? None of the other women make me feel so bad." Mom comes over and puts her arm around you. "Honey, she's worked hard to become a big time model. She just doesn't like that you get all the attention because you have to jizz so much. Trust me, in a few years when you're older, you two will be having sex on this couch laughing about the way she used to treat you."

Your sister comes back down in a stunning strapless red prom dress. It hugs her every curve and pushes her cleavage up and out. This dress caused you to spill more seed than anything you can remember. "Okay sis, now I want you to slowly take it off." Andrea, looking visibly annoyed, starts seductively getting our of her dress. As she pulls her top down, she reveals her massive tits. This is the first time you've seen them, and you immediately fell in love. They were the two most perfect breasts you ever saw. As she lowered the dress down past her waist you got your first glimpse of her fantastic pussy. It looked so innocent yet you knew many guys had pounded it over the years.

As the dress hit the floor and she started to take off the shoes you stopped her. "Leave those on sis. Leave your tiara on too. I want to see what George (her date for prom) got to see on prom night. " Mom interjected, "Andrea, you better not have slept with George. We talked about this. No sex unless you're married or helping your brother." It turned you on to hear your mom chastise your sister for being sexually inappropriate as your mom was snapping nude pictures of her.

You asked your sister to get in a variety of positions. She bent over and spread her ass, she thrust her pussy forward and stuck two fingers in, she even stuck a finger in her ass then put that same finger in her mouth. That last scene was too much to bear; you needed to cum. You yelled out to your sister and your mom.,"I have to cum! Andrea, get on your knees. Mom, get as many pics of this as you can."

You walk over to your sister, aim your cock at her tiara, and splattered it with your jizz. As you came your sister yelled to your mom, "MOM, he's ruining my tiara! I got this for being prom queen!" Your mom responds, "Oh honey, it's a small price to pay for helping your brother cum. I can always get you a new one." Andrea then turns to you. "You jerk, you did that on purpose." You just smile, knowing that you couldn't get in trouble. "So sorry sis, I thought my jizz would hit your face. I had no idea!"

You went into the kitchen to get a quick after-cum snack. As you walked back you saw Andrea still nude, sitting down next to your mom on the couch. Mom had a rag and Andrea had some sort of cleaner. They were desperately trying to get your cum stains off her tiara. From the looks of it they weren't having much luck. As you turned to go upstairs you heard Andrea yell "fuck you asshole." Mom quickly gasped, "Andrea, we don't talk like that in this house. And how dare you blame your poor brother. He can't control where his jizz goes, you know that." You made your way to your room where you quickly fell asleep.
