Bi Sexual Boyfriend Sex Story. First Time With Gay Muscle Stud.

I am a 45 year old woman and I am dating a 25 year old man. We men online at a good dating service and I was attracted to him because he was so cute, and a little feminine and very sexy. Our sex was incredible from the start and was for both of us, the best sex we ever had. We both shared a love for drinking red wine and watching movies and soon, I would find out we both shared a love for muscle studs.

After about 3 months, my boyfriend kept asking me to dress him as a woman and at first I was a little concerned but we ended up having even better sex. It was wonderful how we would go shopping for clothes together and then come home, dress up, and have sex. I began to crave to dress him up as a little sissy slut. I made him look beautiful and any man would be lucky to be with him.

I began to rent gay porn for him and we would dress up as woman and then watch men having sex with each other and talk about how sexy they men were. I then bought some sex toys online. I bought a butt plug, a strap on dildo, and a double headed dildo. My boyfriends butt was very tight so I made him wear the butt plug around the house for a week until it stretched his ass out wide enough that I could use my strap on cock on him.

I was surprised at how much all this turned me on because I never used to be like this. I was so dominant and he was so submissive and sweet, and together we were perfect and having incredible sex. I couldn’t stop. I kept fantasizing about seeing him with another man. I made him look at gay porn all the time, and I made sure I trained him properly about how to suck a cock right. I also made sure I fucked him in his ass every night.

My sissy boyfriend craved to be fucked in the ass with my strap on. Even during regular sex he begged me to finger his butt which always made him cum so quickly. I knew that my boyfriend was bi sexual even if he didn’t know it but I wondered if he was gay. He had never been with a man before but he often fantasized about it. I thought about this a lot and devised a plan to find out if he was gay or not.

 I found a very sexy muscle stud at my gym who was a personal trainer. His name was Byron and we became friends. I suspected he was gay and I was right. Then I told him all about my sissy bi sexual boyfriend and how I was trying to find out if my boyfriend was gay. I asked him if he made house calls and he said he did. So one day, I dressed my boyfriend in a tight white bikini thong with tie strings on the side and then called the muscle stud over.

“Baby, I want you to meet Byron. He is going to be your personal trainer. This is my early birthday present for you. Twice a week, Byron will come to the house, and you two can work out together. Now run along and do whatever Byron wants you to do.” I said.

I secretly watched as my sissy boyfriend worked out with Byron in the backyard. Byron put my boyfriend in all kinds of sexual positions and was holding and touching him. I could tell Byron was enjoying it and that made me happy. The question was, was my boyfriend enjoying it.

I went into the backyard to have a closer look. Byron had my boyfriend laying down on his back doing sit ups with his legs spread wide open. Byron’s huge bulging cock was firmly up against my boyfriend’s ass while is muscular arms held down my boyfriends feet. If my boyfriend got a hard on, his penis would stick out of his white bikini bottoms. I figured it was a type of gay thermometer.

“How’s it coming boys?” I asked.

“We are almost done.” Byron said. “It’s time now for the rubdown.”

I watched as Byron began to apply lotion all over my boyfriends back. Byron positioned himself so that my boyfriends head was faced directly at Bryon’s large bulge in his tight black shorts. I watched as my boyfriend stared at the large bulge in front of him. Was he getting turned on? After a few minuets, I gave Byron a wink that meant it was time to find out what effect all this was having on my boyfriend.

“Ok, now your front. Lets roll you over.” He said.

And sure enough, when Byron rolled my boyfriend over, his penis was sticking out of his bikini thong, straight up in the air. He was very embarrassed.

“I see that you are enjoying your new personal trainer aren’t you?” I said. “Are you attracted to Byron sweetie? It’s ok, I want you to be.” I told my boyfriend.

“Yes, I am attracted to him.” My boyfriend admitted.

“Why are you attracted to him sugar? What do you like about him that is turning you on so much?” I asked.

“Well, he is very strong and big and his has a big bulge.” My boyfriend said shyly.

“Would you like to see what is beneath his bulge?” I asked.

“Yes I would.” My boyfriend said.

I reached over and pulled down Byron’s shorts and out popped a gigantic cock. It was at least 7 inches long and 3 inches wide. Byron’s cock was a work of art and would have turned any straight man gay.

I stroked the muscle studs cock, right in front of my boyfriends face, until his cock was almost completely erect.

“Would you like to know what this magnificent cock tastes like?” I asked my boyfriend.

“Yes but I am shy.” My sissy boyfriend said.

“Don’t be shy, I am here to help you. Just open your pretty sexy mouth and I will place it in there for you”. I said as my pussy began to get very wet.

I placed Byron’s cock inside my boyfriends sissy mouth and he looked up at Byron and I with very submissive eyes.

“Now show Byron how well I have trained you to suck a real mans cock.” I said.

I watched in ecstasy as my fantasy was coming true before my very eyes. My boyfriend’s mouth was engulfed by the super sized cock and he sucked Byron like a champ.

I placed one hand on Byron’s balls, holding his big cock for my boyfriend to suck. I placed my other hand on my boyfriends sissy penis and began to stroke it while he sucked the muscle stud off. I was so turned on by all this I forgot that I was supposed to be deciding if my boyfriend was gay or not. If he was gay, I think that only made me want him more.

“Now my little darling, my sweet sexy submissive boyfriend, Byron is about to cum. You have done an excellent job sucking his cock. I want you to swallow all his cum down your sissy throat until every last drop has spewed from his cock.” I instructed my boyfriend. And he did.

The three of us got into the shower and I insisted that my boyfriend wash Bryon’s body from head to toe. I watched as his hands explored all over the muscle studs perfect form. I began to play with myself and brought myself to several orgasms. My boyfriends cock had been consistently hard ever since he little rub down. I had never seen him so excited before.

We got out of the shower and I personally toweled the two boys down. They stood there naked and looking at each other.

“Now honey, I want you to let Byron kiss you. Don’t be shy.” I said as my boyfriend leaned into the muscle stud. Byron forced his tongue into my boyfriends mouth and grabbed him by the ass as my boyfriend’s hands explored all over the muscle studs back, legs, and chest.

Soon Byron’s wonderful cock was rock hard again. I started to stroke my boyfriends cock, and the cock of the muscle stud together while they kissed. I was about to have another orgasm.

“Ok my beautiful boys, it’s time to lie down on the bed.” I said. Byron and I each took my boyfriend’s hand and led him to the bed. I lay him down gently on his back, then positioned Bryon a the foot of the bed. I helped Byron lift my boyfriends legs into the air and took his big dick and began to tease my boyfriends ass with it. I was having way too much fun.

I got the lube tube and squirted a healthy dose of lube all over the gigantic cock, and the sweet virgin sissy ass of my boyfriend. Then I took Bryon’s cock and placed it into his ass.

“There honey, that’s what you have been wanting now for so long isn’t it?” I said.

“Oh yes.” My bisexual boyfriend replied. I then leaned down and began to kiss my boyfriend as Bryon began to thrust his cock deep into him. I pinned back my boyfriends arms while I kissed him gently and talked dirty to him.

“Doesn’t that feel good. Oh you like it up the ass so much don’t you?” I said.

And then suddenly, my boyfriend came all over his stomach without anyone, or anything even touching his penis.

“Aww sweetie, you came so fast. You love this don’t you. I knew you would. But now you are just going to have to lie there while Byron fucks you some more.” I said.

But within a minute, my bi sexual boyfriends cock was hard again.

“Baby, look how much you like this. I have never seen you get so hard, so quick after you come with me.” I said.

Byron turned my boyfriend over placed him on his hands and knees on the bed. He bend him over and began fucking him in that position. I took out a large vibrating dildo and shoved in into my pussy as I watched Byron thrust his gay cock faster and faster into my boyfriend’s tight ass. Byron reached around and began to stroke my boyfriend penis faster and faster. Then Byron came into my boyfriends ass, while my boyfriend came in Byron’s strong muscular hand. They both cried out in pleasure. Watching my bisexual boyfriend having his ass pounded for the first time with a gay muscle stud made me have an orgasm too. We all came together.

I kissed my bi sexual boyfriend deeply and rubbed his head and asked, “Well sexy, now that you have finally had sex with a man, which do you like better. Boys or girls?”

“Both.” he said.
