It was a summer afternoon and I was on the phone with my brother. We've been in a relationship since we started having sex twenty years ago when I was eighteen. Jack was twenty then, and still living at home. Now I'm thirty nine and Jack is forty one. He's married and I'm recently divorced with an eighteen year old son, Sean. My brother and I live far apart, but we meet up every few months for "hot weekends" and we have phone sex when Jack's wife is out.
Jack says taboo sex is so good that sex with his wife or girlfriend can't compete. You could say that's how he rationalizes cheating on his wife with his sister, but there may be some truth to it. Just knowing I'm getting naked for my brother and him knowing he's going to fuck his sister makes us incredibly horny before we do anything. Taboo sex never loses the thrill.
I was kneeling on my bed naked, looking at myself in the mirror, imagining Jack was watching me, stroking his cock as I masturbated. My big tits stuck out, my nipples aroused and stiff. I wished Jack was there so I could feel his eyes on my body. My shaved pussy was swollen and dripping. I had been rubbing my clit for half an hour, bringing her to the edge of orgasm and then slapping her hard to stop her cumming. I could smell my pussy scent and that makes me extra horny.
Jack aroused me by making up fantasies about us. Sometimes he talked about his friends and him tying me to the bed and using me as their sex slave. I often masturbate imagining stuff like that and Jack knows all my kinks. Lately we had been fantasizing about me seducing my son. Sean is 18, tall and well built and I know he has a nice cock. I walked in on him once or twice without knocking and caught him with my panties wrapped around his cock. His friend David likes my tits. He and Sean masturbated together using one of my bras. They must know it turns me on that they sniff my underwear because they left my bra all soaked in their cum right on top of a pile of laundry. When I found the bra they had each cum in one of the cups! It turned me on so much that I put it on and dipped my hard nipples in their semen.
Jack always flatters me that everyone in our family wants to fuck me. It makes me hot when he breathes this stuff in my ear down the phone. When I'm fantasizing, I like to imagine being a complete whore, free of all constraints and fucking everyone, men and women. I've thought of making my fantasies work for me and becoming an escort. Being flown from city to city in private planes with rich young executives fucking me at 35,000 feet for thousands of dollars a pop sounds like a good gig.
"You know Sean wants you Mary, I've seen how he looks at you," Jack was saying in my ear. "He drools over your tits. When my son Billy came to visit you, he couldn't stop talking about you after he came home. He has your picture in his room and I know he jerks off thinking about you. Our cousin Jay is crazy about you too. He told me he'd fuck you if you let him. You could have any man you want, Mary. You said Sean steals your panties and cums in your bras. He's a horny young guy and you know he thinks about your pussy and your tits all the time. Why don't you take pity on him and give him some relief? Go visit him at his new place. You'll have privacy and nobody will know what you're doing with him."
Jack was getting me very horny talking about my son that way.
"Jack, I'm gonna visit Sean soon and give him my pussy just so you'll shut up about it. I'll tell you about it on our next call."
"Oh Fuck Mary! Are you serious! That's so hot. I'm cumming!" Jack moaned, then his phone went dead suddenly. His wife came home, I thought. He left me hanging again! I was still in the middle of my fantasy about my son, when the phone rang again. I thought it was Jack calling me back, but it was Sean!
I picked up my phone, still touching myself. It was the first time I had ever talked to Sean while I masturbated. I was still wrapped up in Jack's fantasy and now I was talking to Sean all naked and horny! I thought "I could have phone sex with Sean without him knowing it!"
I wondered if Sean would be able to tell I was masturbating while we talked. I kinda wanted him to. I told him right away how much I wanted to see him.
"I miss you, Sean," I said, caressing my stiff nipples and imagining Sean touching them.
In the state I was in, my voice sounded sexual and seductive no matter what I said. I had been having phone sex with my brother for years and I was used to feeling the sexual vibes in his voice and mine as we brought each other to orgasm.
"I miss you too Mom," Sean said brightly.
"I really miss you, baby," I said, "It's lonely here without you."
As I said this I was fingering my slit.
"Yeah Mom, I know," Sean said, "You should come visit!"
"I want to cum and I also want to visit you baby," I breathed, touching my clit and hoping he picked up on the double meaning. "I want you to hug me!"
I wanted Sean to hug me when we were naked and feel my bare tits on his chest. I knew my voice sounded horny and that made me hornier. I was going to cum soon and Sean would hear me moaning in his ear.
"Yes Mom," Sean said innocently, "I want to hug you too."
I pictured Sean touching his stiff cock. I wanted him to imagine me naked and I wanted to make him cum with my voice! I couldn't think of way to hint that he should masturbate while talking to his Mom!
The only thing I could do was be honest. What if I tell him I'm naked? Jack had left me so horny that I couldn't control myself.
"I'm naked Sean!" I suddenly burst out. "I'm kneeling on the bed with my bare tits sticking out, stroking my nipples. Remember when you jerked off in my panties baby? Do you think of me in that way sometimes? It's natural baby and I like it that you find me attractive. Do you stroke yourself and cum when you think about my body?"
"Oh God Yes Mom," Sean breathed. Sean sounded very aroused by what I had told him. That made me bolder.
"Thanks for being honest Sean. I love you. I want you to touch your cock for me now Sean. Pull it out honey and stroke it for me. I want to hear you have an orgasm. Think about me naked right now. My tits are big and horny! If you were here I'd ask you to suck them and cum on them! Would you like that?"
"OH FUCK Mom!" Sean groaned. "I want to see your big tits!"
