The thought of sharing my girlfriend with someone has always aroused me. I had jerked off to it countless times. One night after a long session of love making I broached the subject with her.

I was surprised when she said the though of it was kinky and made her all horny and wet. Needless to say we played our brains out that night.

I didn't bring up the topic for a few days. I realized that my most recurring fantasy was of sharing my girlfriend with an ex-boyfriend of hers. I told her off my fantasy and wanted to know if she would fulfill it. She agreed. Since her ex lives in the same city as us it was no problem getting a hold of him. We decided to go out for drinks. My girlfriend wore a sleeveless black shirt with a very low neck exposing her cleavage.

She wore a mini-skirt without any panties. She was looking absolutely gorgeous.

I was excited and also a bit nervous.

Anyway, the evening went smoothly. Before I knew it we were feeling tipsy and more and more comfortable with each other. I must point out that Tom the ex-boyfriend had no clue what my girlfriend and I had planned for the evening.

Throughout the night she was flirting with both Tom and I making it looking innocent. I could tell that he was excited by the bulge in his pants.

After a while I suggested that we go back to my place and get more comfortable. We got home and planted ourselves on the same couch. Then I was told to go fetch everyone a beer from the fridge. When I returned I noticed my girlfriend had her hand on Tom's crotch and was gently rubbing it back and forth. This got me very excited. Tom felt a bit awkward when I returned but I put him at ease by telling him how excited this was making me and that I had fantasized about this moment for a long time. I told Tom to take my girlfriend's shirt off. He did as I ordered. He then proceeded to take off her bra. By this time she had unbuttoned Tom's pants and was holding his throbbing length in her hands. Tom was now squeezing her breasts and pinching her nipples. His other hand was underneath her skirt fingering her sweet softness.

As I took out my own length and began to rub it back and forth, I ordered them to kiss each other.

Before I knew it they had their tongues down each other's throat. Tom made my girlfriend lie down and started to rub his thingy back and forth across her wet softness. She couldn't help but moan and ask him to play her?..

and that he did. While she was getting the playing of her life she took my thingy into that sweet mouth of hers till I blew a load down her throat which she managed to swallow most of it.

Tom let a gallon of cum deep inside her softness. And according to her she had multiple orgasms for the first time in her life. After Tom left we had the best lovemaking session of our life and agreed to do this more often and we both enjoyed it so much. We had several threesomes after that till the day we broke up. I am hoping that I get the same invitation that Tom did, sometime soon.
