I find it unusual that the only time I would get upset was when Dawn had a cock in her pussy. It was as though that hole was toVW sacred. I recall one other time that her older brother, Marc, fucked her. He came over our apartment to talk. His girlfriend, Roseann, was acting different and he wanted to know if Dawn had any idea what was going on with her. Of course Dawn knew. She was having sex with us. Dawn asked Marc in what way was she different? Marc explained that she shaved off her pubic hair and seemed more open sexually. He thought she was having an affair with another man. Dawn wanted to keep our threesome private so told her brother that she didn't think Roseann was seeing any other man.

"Marc, she is having an affair with me." Said Dawn. "She was afraid of losing you, so she came over when Gene wasn't home. I dressed her and shaved her and taught her how to make love to a woman. She quickly learned and comes over frequently for us to fuck each other. So, she doesn't have time for anyone else."

"Has Gene been a part of this?

"No, it is just us girls."

"I want to see you two together."

"Well why don't you and Gene setup the bed in the living room and I will go get Roseann. She is going to be scared of how you react so this will allow me to talk to her first."

She left, Marc and I bought three bottles of Moët and met them back at the apartment. When they came back the bed was set, the champagne was chilled and Marc and I were both horny. They walked in and Roseann tried to apologize to Marc. He wasn't interested. He just wanted to watch the girls to see if what his sister said was true. I poured the girls champagne and they both stripped naked. I had to pretend that I was seeing Roseann naked for the first time. I complimented her and was told by Marc that he had no intention of sharing her with me.

As I have said previously, Dawn looked like a young Ginger Lynn, Roseann was even smaller with almost no tits, but had a tight little ass. Dawn leaned into Roseann and started kissing her. Roseann responded to Dawn's kiss and soon they were swapping spit. Their tongues were going in and out of each other's mouths and there was no question that they had done it before. Soon they were caressing each other's tits. Dawn started to suck Roseann's nipples and soon they were sticking out a good inch from her body. Marc and I both got undressed as Roseann returned the favor. Soon the girls were in a sixty nine position. Roseann was on bottom with her head by the foot of the bed, with Dawn kneeling over her. Marc climbed onto the bottom of the bed to watch his girlfriend eat out his sister. Roseann had Dawn's clit in her mouth and was sucking furiously. She also had a finger buried in Dawn's ass. I moved to the top of the bed and realized that everything Roseann was doing, Dawn was copying her. So Marc was watching his girlfriend getting assfucked by Dawn's fingers as well as having her c unt eaten. But what was really facinating him was watching Roseann do it to Dawn.

"I want a cock," said Dawn. "I want to be fucked." Marc raised onto his knees. Roseann released Dawn's clit and started sucking Marc's cock. I was waiting for them to move so I could give Dawn what she asked for.

Suddenly Roseann removed Marc's cock from her mouth and lined it up with Dawn's pussy. "You heard her baby. Your sister wants a cock. Fuck your sister for me. " Marc pushed his cock into his sister's pussy. "I want to watch you come in your sister's pussy. I love it when she comes. She normally squirts right down my throat." She has convinced Marc that she not only lives with him but has an ongoing affair with his sister as well. I said that I would not fuck Roseann so I moved to the bottom of the bed to get a better view of what they were doing. I started to get jealous as I watched Marc plow his sister. I wanted to stop it, but I couldn't.

"Marc come inside me please. Come inside your little sister. Your cock feels so good. I am going to come in Roseann's mouth. When you come inside me, we can have her eat it out. Please fuck me harder."

Marc started to pound his sister. His seven inches were inside her for only the second time ever. Roseann was sucking on Dawn's clit and she lightly bit it. Dawn started to squirt all over her brother's cock and Roseann's mouth. Marc shoved his cock in as far as it would go and released his sperm. He came inside his sister again. He slowly pulled his cock out of his sister and Roseann captured it in her mouth. She cleaned his cock of all their juices and then moved to Dawn's pussy. Her boyfriends sperm was starting to leak out and she caught it on her tongue. She then stuck her tongue deep inside trying to get more. She sealed her lips around Dawn's pussy and started to suck as hard as she could. I moved back to the head of the bed and put my cock in front of Dawn's mouth. I had been jerking off so long that as soon as she put her mouth on me I started to come. Because her mouth was right over Roseann's pussy, a lot of come dripped down onto it. Dawn pushed it inside Roseann. Then I realized that Dawn was still holding my come in her mouth. She dropped her mouth onto Roseann's pussy and started pushing my come into Roseann's c unt. She stuck her sperm covered tongue into her as far as she could leaving my come there. Marc was moving away from his sister as she was doing this.

"You didn't just fuck Roseann, did you. I told you that we weren't sharing her with you."

"You fucked your sister and came in her pussy, but you are worried about me fucking Roseann? Don't worry, my cock didn't enter her." The girls went to shower and we cleaned up. Once again a guy came in Dawn's pussy without my permission.
