My brother Alan and I had been fucking for several weeks now. We planned our lives so that we could get together as often as we could. Once I had experienced fucking with him, I simply couldn't get enough. Lucky for me, my husband was spending a lot of time out of town on business.
Alan and I experimented with many different positions and we fucked in every room in both, my house and his. Although, we enjoyed fucking in every position we tried, I think, our favorite was with me on top. Alan enjoyed playing with my big titties while we fucked. He loved the way they bounced as I rode him. I simply loved riding his big cock.
One evening, after a very nice fuck, we were lying together talking and the subject of our younger brother Robbie came up.
"Sis, have you ever thought about fucking Robbie?" Alan asked me.
I rolled over so I could see him better. "Yeah, I think about it. I think it would be great to be able to fuck both of you." I told him. "Do you think Robbie would want to fuck me, too?" I asked.
"Actually, I think he would." Alan said. "We might have to get him used to the idea, but I think he would enjoy it very much. I have some ideas that I can use to see what he thinks about it. If I think he is receptive to the idea I will let you know and we will work out a time and place."
"Sounds good to me." I told Alan as I cuddled closer to him.
A few weeks passed before Alan called me with any news about Robbie. He told me he had been sending him links to some good incest stories on the web. Alan told me that after talking with Robbie he felt we could go through with including him on our fuck sessions.
Since Robbie's birthday was only a couple of weeks away, we decided to make that our goal. To give him a great birthday surprise. Alan borrowed a cabin in the mountains from a good friend for a couple of weeks, and invited Robbie and I to come stay with him for a few days. I went up a day before Robbie, so Alan and I could spend some quality fuck time with just the two of us, and to get things planned out.
We went through several scenarios before we finally decided on the way we wanted to give Robbie his birthday present.
Alan and I had spent the night fucking and woke anticipating the day. We knew that it was going to be an awesome day. After all, it was Robbie's birthday!
Alan left later in the morning to pick Robbie up at the airport and drive him to the cabin. I began preparing myself to be a birthday surprise.
After a long bath and a glass of wine, I had become very relaxed and horny. I decided against fingering myself, since I wanted to save it for Robbie. I looked at the clock; "They should be here soon." I thought. I turned on some music, lit some birthday candles around the room and made sure the bed looked nice.
I went to the other side of the room and stood in front of the mirrored panels on the wall. Removing my robe, I stood looking at my plump body, my big titties, big ass and furry pussy. Alan loved caressing my body, I hope Robbie enjoys BBW's too. I loved the way the mirrored panels reflected the action on the bed. Clearly this had been designed with sex in mind!
I heard a car in the driveway. I looked out the window and saw that it was Alan's car. Stepping back toward the bed, I began doing as Alan had instructed me. Laying my robe across a chair, I got on the bed, naked, and arranged myself in an erotic position. I was lying a little on my side, propped up on some pillows. I heard the door open and I could hear them talking. My pussy was getting so wet just thinking about what was about to happen!
I heard the knob on the bedroom door turn then I saw Alan as the door opened. He looked at me with a big smile on his face. I knew he liked what he saw. He came on into the room, leading Robbie, who had a blindfold on. Robbie was kind of floundering about. Alan led him almost to the bed.
"Robbie, before I take the blindfold off, I just wanted to let you know that Sis and I wanted you to have the best birthday ever, so we are giving you the best birthday present you could ever have." Alan told him. "There is just one rule we have for you."
"And what might that be dear brother" Robbie replied. "You are beginning to get me a little worried".
"The rule is: you have to promise to try what we give you." Alan said. "Can you do that, little brother?" Alan asked.
"Well, you know me, I will try about anything once," Robbie said. "Sure, I'll agree to that."
"O.K. baby brother, here you go!" Alan said as he reached up and undid Robbie's blindfold. "Happy Birthday to you!"
I heard a sharp intake of breath as Robbie's eyes looked upon me, his naked sister lying on the bed offering herself to him.
"Wha-wha-what are you all doing? Robbie stammered. Sis, you are naked! What's going on here"
I looked at Robbie, a sexy pout on my face, my hands rubbing my tits,
"Happy Birthday Robbie." I said. "What do you think about your birthday present? Do you want to cum play with it? I asked him as I began rubbing my pussy with one hand.
"You are my birthday present, Sis?" He asked still astonished. "To have sex with?"
"We can't do that, that's incest! Robbie protested. "It's not right"
Alan had moved over to the bed and sat down on the other side. He moved close to me and began rubbing my arms.
"Robbie, you promised to try what we are giving you." Alan reminded him. Alan proceeded caressing me, his hand rubbing my big tit. "I promise you won't be disappointed, little brother. Our sissy has a great pussy." Alan told him.
Then it seemed as if Robbie finally understood. He looked at Alan, and me so comfortable together, "So how long have you two been fucking," he asked us.
"For a few months now," Alan replied. "It has been the best fucking I have ever had, Robbie. For Sis too, and we thought we would like to share this with you."
"Robbie, why don't you and Alan go ahead and take your clothes off, and let's all just be naked together for awhile." I suggested. "Then if you decide you don't want no part of this that will be fine, just don't ruin it for Alan and I. Fucking with Alan is the best sex I have ever had and I don't plan on giving it up." I told him.
I could tell that he was torn about what to do. He was getting aroused; there was no doubt. I knew that if I could just get him naked and on the bed, he wouldn't want to stop.
Alan had started removing his clothes and was soon naked. I saw the silent battle in Robbie's eyes as he looked at me, his sister, naked and offering herself to him. His gaze took in my big titties then traveled down to my pussy. It is covered with a neatly trimmed patch of dark fur. I spread my legs just a little, so he could see my pussy lips open for him. As his gaze took this in, he started unbuttoning his shirt. I felt a little bit of triumph, especially as he took off his pants and underwear, then stood in front of me naked. It had been many years since I had seen my baby brother naked.
His cock was now about 7 inches long, not quite as thick as Alan's but a nice one all the same.
I sat up on the bed and leaned toward him. I reached out and took his erect cock in my hand. I felt a shiver run through him.
"Oh! Robbie, your cock is beautiful! I whispered to him. Slowly I started rubbing it, stroking it from the tip to his balls. I wrapped my hand around the shaft and started pumping it.
"Sis, Oh oh, oh, Sis it feels good." Robbie murmured. We can't do this though. It's wrong. This is incest!" Robbie protested to me. I kept stroking his cock. He had his hands on my shoulders now. I looked up into his face. He was looking down at me, watching me pump his cock.
Robbie," I said. "I have already fought that battle when Alan and I started fucking. He fought it too. We both realize that to some people this would be wrong. But we are adults. I am almost 40 and you two are in your 30's. We should know what we want from sex and whom we want to have sex with. I know that I want to fuck you and Alan. Go with your feelings, Robbie." I encouraged him.
I leaned over and put my lips on his dick, kissing it's throbbing head, licking the tip with my tongue. I ran my tongue up and down his shaft feeling it harden. I heard a sharp intake of breath from Robbie as I began slowly sucking it into my mouth. Inch by inch I devoured his big cock, sucking it hard. He had his hands on the back of my head, holding me to his crotch. I knew he wouldn't turn away now.
"Oh, sissy, you're sucking my dick" Robbie moaned. "You've got my dick in your mouth sissy!" "It feels so good sissy. Yes! Yes! Sissy suck your baby brother's dick, suck it hard!" He cried out.
I did just that. Sucking on his cock, licking up his precum. I didn't want him to cum soon, so I pulled away from his dick and raised up to look at him. Lust was burning in his eyes. His hands found their way to my big titties. He took them in his hands, caressing them. Rubbing my already hard nipples with his thumbs.
"Yes baby brother, play with sissy's big titties. Rub sissy's nipples." I moaned as feelings of ecstasy ran through me. "Suck them, Robbie" I cried out. "Suck my big titties".
Robbie sat down on the bed, and I turned to him. Holding my tits in my hands, I offered them to him. He leaned over and pressed his mouth to my right tit. I felt his breath on my nipple, then his moist lips as he kissed my tit. I felt his tongue begin to lick on my nipple. I lowered my eyes so I could watch my baby brother feeding on my tits. He was licking harder, then sucking on my tit. In no time, he had latched on and was sucking my tit hard.
Oh, yes, Robbie! Suck my tits baby brother, suck them hard." I was crying out. "Let sissy feed you with her titties baby brother."
