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.
