Friends and friends of friends came to make swaps. I wonder if I want to enjoy my body as though I can change again. Any boy in this room would be delighted to have Jennifer's Body. Suddenly I feel a hand on my hips and a deep voice slips into my ear.
"Hello darling"
I jump and see Gavin, Jennifer's boyfriend. He is a 24 year old black man. 6 feet and 5 inches and very muscular. I'm freaking out. But he says he was waiting for me. He was about to swap with one of his friends but he prefers to do it with me. Phew, I'm lucky he thinks I'm Jennifer. I do not contradict him and we head to the cabins. Flash! I'm now in Gavin's body without even having to ask for it. One of the most masculine guys I know. A astonish "Wow" get out for my mouth with his grave voice. My view is much higher and everywhere I look down there is nothing but muscle. I'm in heaven. I am getting hard with a very big bump on my pants. Well, happy to have a dick again. Gavin, now in Jennifer's body approach me.
"Looks like you're in a hurry sweetie, comes"
Then he leads us out of the laboratory and we jump in his car. Arriving home we go to their room. While I take off my shirt I jokingly say to myself what I'm doing is very bad. A real man will make love to him and he will not even know it. Ha ha. In the room I finally pull down my underwear and I discovers Gavin's huge member. Probably 8.5 inches long and very thick. I suspected because I felt it against my belly. Indeed I never was floppy since I entered this body. I look at Gavin, he have his eyes fixed on my ... his former cock.
"Uh it's amazing, it seems bigger from my point of view" Gavin said very surprised. And adds "We'll wait for the blowjob." He tightens his two little girl hands on my shaft.
"Oh shit, look at your hands' size over my dick" That touch causes an electric shock in my cock and excites me.
"Let's go to the next step," I said, trying not to reveal my urge.
We throw ourselves onto the bed, him under me and he took the opportunity to kiss me on the mouth.
He says "It's weird to kiss a guy huh?" I confirm that I have the same feeling.
Then I move down in order to put my huge cock in front of his vagina.
"Do it slowl..."
And I sink to the end.
"Ouch. Gosh Jennifer it's ... arg! I feel fulfilled."
His breathing is greatly accelerated. I start fucking him. Gavin do smalls squeaks to each of my hip thrusts, then he is able to relax and be less uptight. He enjoys the moment and begins stroking me while I'm above him. I take much more pleasure when he strokes his hands on my black beefy body. He starts with my very strong and shaved chest. Then he stroked my stone 6 pack. And finally finish with my two arms resting around him, strong and hairless arms.
Gavin orgasm first. It's very strong, I thought he was going to faint. I don't stop and one minute later Gavin have another orgasm. His eyes initially show astonishment then he returned to the seventh heaven. I am very proud because this is the first time it happened to me. Finally, it's my turn. Only a series of animal growl get out of my mouth. My penis expels streams of semen into Gavin's vagina. This is the first time I cum with another man's cock and I've the feeling that pleasure is proportional to the size "Oh ..." I collapse on Gavin.
After regaining my breath. I lie on my back and look at my athletic body and my big flaccid cock still covered by cum. Finally I ask him how feels sex by the women side.
"Unbelievable there is no word to describe it. And you, I'm sure you loved the feel of male side?"
Here, I made a mistake, I was still in the clouds because I told him that I am used to but it was very good too. Gavin suddenly looks at me with eyes wide open.
"Oops," I said.
"Wait, you're not Jennifer! And you're a guy!" he said red with anger. And adds, "Who are you?"
I prefer to answer him that I am only one of his acquaintances to avoid problems later. Then he began staring at me while I get dressed, eating his nails. He may think that he gave his body without thinking of it and he is worried about what I'll do with it.
