Threesome With My Gay Neighbor

After our first sex adventure we both became quite open to each other and used to tell all our dirty secrets to each other. During one of those confessions I told her that I am a bisexual person and my first is with a gay who is our neighbor. She got very curious when she heard it and wanted to know more as she never new anyone who was gay though she heard it from her friends. I managed some gay porn video and showed it to her. She was very turned on seeing all this and wanted to see it live. I told her it can be a very dangerous gamble that we play as it can leak our relation to others. But we planned it out in such a manner that my neighbor will never be able to disclose it till the day he is dead. Before I got in a relation with my sis I used to visit my neighbor almost daily for my sexual release but it got reduced a lot as I started getting all my needs satisfied at home. I used to go to him only when I felt like having something different or if sis is out with her friends. He started asking me if I have lost interest in him or if I have found a new GF which I shrugged off. So I made a plan and asked him to come over to my place tomorrow as no one will be there in the house and promised him something very kinky which he had never experienced in life. When he came to my house first thing I did was to blindfold him. 

He got very excited then I told him to take of his clothes which he did instantly. All along my sis was peeking from door crack and getting herself horny. I tied his hands to his back and put my leather belt in neck and made him sit like a dog in his knees. He was doing it so happily his cock started to get hard it was beautiful about 7 inches and a bit curvy. I switched on my music system and started playing hard rock music. In the meantime I signaled my sis to come in. I asked her to undress me and herself. I touched my sis cunt it was soaking wet she was enjoying all this very much I kissed her then I went to him and whispered in his ears that today he is our slave to which he asked me who is we. I slapped him and told him he is a slave so keep his mouth shut and do what we want. He nodded his head. I said you need to get punished for this offense and spanked his white ass till it got red by my spanking. All the while he was moaning in pain and pleasure. His cock was standing like a pole. I stopped to spank him and stood in front of his face I was also semi-erect by now. Sis came beside me and started to give it a rub while I kissed her and started finger fuck her cunt. I asked him to open his mouth and put it inside. He started to suck it like his life depended on it I signaled my sis to bring the camera to take a snap of him sucking my dick we wanted to use it as a bargain tool if he ever wanted to talk about it to someone outside of our sex circle though we never had to cause he kept it as a dirty secret till today.

Coming back to the story after getting sucked for 10 minutes I withdrew from his mouth pushed my sis to open her legs in front of his mouth. I whispered in his ears that the kinky surprise is this and shoved his mouth into her wet cunt. For a moment he paused and hesitated confused what was happening. As he was blindfolded and hands tied-up he was helpless at what was happening but he asked me who is it to which I slapped him very hard in his ass cheeks he cried out in pain and started licking her cunt like a loyal puppy. The moment his tongue touched her clit she screamed out in pleasure and grabbed his hairs to push his tongue inside her. I went behind her and grabbed her tits and started to pinch her erect nipples while I rubbed my hard cock in her ass crack. 
I took her tongue in my mouth and sucked it for a while then I sat on my knees behind her and opened her chubby ass cheeks to shove my tongue in her ass hole we both were fucking her now simultaneously with our tongues and she was moaning like a whore it went on like this for a while before her legs started to tremble with an huge orgasm. She was squirted like I have never seen her before. I asked our gay slave to drink it all not to waste anything which he happily did. 
After she was done squirting she told me that she never experience anything like this to which I replied many more are still to come and kissed her. She asked our gay slave to stand up and grabbed his hairs and started to kiss him passionately. She asked him to pull out his tongue which she started to suck. I was quite turned on seeing her kissing a guy in front of me I grabbed them both and kissed them hard. She was looking at his hard cock so I asked her to suck and pulled her to suck me a little so that I get lubricated with her saliva before I fuck his ass. I went behind him and opened his ass cheeks to lick his ass hole while she continued sucking him. He was making a lot of moaning noises it meant he was now ready to get fucked hard. I placed myself behind him and shoved my hard cock in his hole at a one go it was used to it so without any problem it went in. It felt like heaven I was also very hot by then I just wanted to get my release as fast possible so I pounded him like never. I didn’t lasted very long pulled out just in time and came in loads in his ass cheeks. 
He also came at the same time and my sis drank it all up. She was smiling and saying that it tasted very nice. We all rested for a while and then I asked him does he want to see who sucked him off today. He said yes but I told him that it needs to remain our dirty secret to which he happily agreed. So I signaled sis to untie him and take of his blindfold. When she finally took of his blindfold he was stunned to find my elder sis buff naked in front of him. He was unable to speak for a while but my sister broke the silence by saying that it’s ok as we all three are bloody sluts. He was quite turned-on seeing my sis naked which surprised her as she thought he was a pure gay to which I replied that don’t forget he is a married guy and he also fucks his wife once in a while which made us all laugh. We opened up 3 beers to relax a little and rested for over 30 minutes. Now it was time to fuck my sis as was only sucked last time I told her that now she will see stars like never before. I and our neighbor started kissing and licking her all over the body. We took her big nipples in our mouth and sucked them simultaneously while I played with her slit and he fingered her ass. 
She started to moan again we both stood in front of her mouth and she started to suck us both one by one. When we both got hard and ready we made lie on her back and spread her legs in air and started to fuck her like maniacs taking turns after every 3 minutes. We did her ass also the same way taking turns every 3 minutes then she squirted again like a river. I asked him to push his cock in her mouth while I lick her juices. I asked him to fuck her again in her pussy while I placed my cock again in his ass hole. 
We all were fucking each other in the same moment his cock in her cunt while I was inside his ass. I was about to cum so I pulled out and relaxed myself as I wanted to cum inside my sis ass. I asked him to lie in his back so that she can ride him in cowboy style while I placed my cock her ass. She was about to get sandwiched first time in her life I asked to relax a little bit before I shoved in my cock inside her ass. She squealed in pain and pleasure but we got the motion going perfectly in a few moments and she was shouting to fuck her harder. While doing her I told him to cum inside my mouth as I wanted to taste it hearing this my neighbor couldn’t control himself any longer he pulled out just in time to push it inside my mouth and I swallowed it all. It took me another 2 minutes before I started to release my juice inside my sister’s ass. 
We all collapsed in the bed all our strength drained out from all this fucking. Cum was still dripping out of my sisters ass hole I asked her not to waste it so she used her finger to finger her ass and started licking it. She asked our neighbor to help her he laughed and pulled himself to her ass and licked it dry of my love juices. It was getting quite late so he bid farewell and thanked us for a great time. I and my sister went to for a bath together to clean ourselves while soaping each other she thanked me for today’s wild fun and kissed me. It was very passionate kiss which turned me on again. My cock was again up though we both were very tired we still made a passionate love under the shower the best part was it was more of love than horniness for each other which made it the best fuck of the day…
