My girlfriend and I had fantasied together many times about having a threesome with another man and me watching her having sex with a well hung guy. She loved sucking and fucking the large dildo I had bought her while I watched and she got so hot when I was inside her while it was in her, she really wanted to have two cocks in her but the right situation have never arose.
I decided the time had come to make it happen. A few weeks before her 28th birthday I had booked a male stripper to come to our flat and do a private show. He was carefully selected as I knew he would have to turn her on before she had time to over analyse the situation and back out, I had spoken to him to arrange the "extras" I wanted other than the strip and he sent me some pictures to confirm he had the "tools" for the job and when I saw I knew she wouldn't be disappointed!.
So the morning of her birthday arrived I presented her with her presents and breakfast in bed. I got her presents with this evening in mind sexy underwear, stockings, some killer heels and a new skirt suit to wear that day to work. I explained she had to wear this complete outfit to work today and tell me all about it when she got home, she gave me a cheeky smile and i knew what she was thinking, she loved winding up the men in the office and then telling me all about it. The suit was a little inappropriate for her office as the skirt was very short but I knew how turned on she would get with the men in the office looking at her long thin legs and being able to see much more than usual.
The desks in her office were open fronted so if she wanted (and she probably would) she could give them a little show by crossing and uncrossing her legs. We got up and showered together it didn't take long before things started to get steamy, I wanted her to be gagging for sex when she got home so sex was off the cards for this morning. I quickly knelt in front of her and grabbed the shaving foam, moistened her pubic hair and grabbed my razor. I had one of those razors with the battery powered vibrating head and needless to say within seconds she was moaning in ecstasy as I shaved her pussy smooth, once shaved clean I stared to lick her clitoris with long steady strokes until I felt her legs start to tremble and she had her orgasm. My cock was throbbing by this point but I was determined that she wouldn't have a cock inside her until tonight, I stood up and told her to squat down and I started to jerk myself off all that was filling my head was images of the evening ahead of us, she was furiously rubbing her pussy and thrusting fingers inside herself and it wasn't long until I shot my cum over her small perfectly formed breasts she straight away rubbed it across her tits, down her stomach and brought herself to orgasm again rubbing my cum into her pussy. We finished up in the bathroom and went and got dressed, watching her dress that morning in the new black lace underwear I had chosen, padded bra, suspender belt and stockings, thong, those 4" leather heels and the short skirt suit that was going to turn every head she passed sent my heart racing, if only she knew what was ahead for her when she got home tonight.
The evening was here! I had got home about an hour before my girlfriend so I could make sure everything was ready, I had spoken to her entertainment for the evening and everything was on track, I had booked him for a few hours so if things went well they could carry on. I had spoken to my girlfriend while she was in her taxi home, she told me of her antics that day one of the men who's desk was facing hers was continually looking at her legs through the front of her desk so she had given him a full view up her skirt for a few seconds while she pretended not to be aware of him staring at her and went over to his desk and lent over to him giving him a clear view straight down her top as she was talking to him about work, she could see by the bulge in his crotch that he was hard and she left him there unable to stand up for quite some time. When she got home I had left a glass of Champagne and a little "pick me up" by the front door for her, she consumed both and came and found me. I topped her glass back up and told her there was a surprise on the way she tried to get me to tell her what but there was no way!
We chatted for a few minutes about her cock teasing with her colleagues and it was obvious how horny she was. She went to the bathroom and then there was a knock on the door, I answered it, her present was here! I led him to the living room and quickly ran through my plans again, he agreed to strip for her, and to have sex with her while I was there. I left him there and went to find my girlfriend, I heard him put music on as i left the room, she came out of the bathroom as i approached the door she asked who was at the door and I said that her surprise was in the other room waiting for her she looked excited and intrigued.
