First bi and group experience - mmf SeXStoRY

I started a new part time job driving a limo a few weeks ago. I got the call to pick up a couple at their home and they were going clubbing. They lived in one of those gated communities, and when I picked them up she was gorgeous. She wore a tight fitting black skirt, 5" heels, and a revealing blouse showing off her 36c's. Her name was Debbie and his was Mike. Mike asked me to drive into the city to a club they knew. I waited outside in the car for about 4 hours until they called for me to pick them up. They had quite a bit to drink and asked me to drive them home. On the way home, they started to get it on, and before I knew it she was naked and his pants were off. I could hear all the moans and couldn't take my eyes off the mirror. Then I heard Mike say, "you like what you see?". Apparently he noticed me looking at his hard 9" cock going between Debbie's perfect tits. I said "you bet." Then why don't you pull over and join us, said Debbie. Not ever being put in this situation before, I was shocked but agreed. After finding a dark quite place to park, I got out of the drivers seat and hopped in back. There before me was this beautiful women and this guy with the most perfectly shaved cock standing at attention. Debbie reached over and started undressing me while she pushed my head down on Mikes cock. All I could do was open my mouth and accept his hard member. I had never had someone else's cock so close to me and it felt fantastic in my mouth. While Mike was pushing his cock down my throat, Debbie was hard at work on my shaft. After she got me hard, which really wasn't that difficult, she mounted my cock, reverse cowboy style. From the outside of the car it must of looked like something really great was happening inside. It must have been bopping up and down. While Mikes cock was pushing on the back of my throat I could taste his precum. It was hot, salty and made his cock even taste better. I never even dreamt of sucking cock before, but here I was, with Mike's cock sliding in and out of my mouth. Then I heard Mike scream, I gonna blow my load. With that Debbie jumped off my cock and came up to me where I was in front of Mike. Mike pulled his dick out of my mouth just as he was shooting his hot load all over Debbie's and my face. And it was a huge load, and Debbie and I both had our tongues out eagerly accepting his juice. Debbie and I layer there as we were covered in cum. After Mike finished, Debbie and I swapped his cum back and fourth and rolled it on our tongues. Mike then came down and Moises Debbie too. After we had cleaned up Mikes cum, they both went to work on my cock. It didn't take long for me to unload, and they both cleaned me up. After dropping them off back at home, I got an extra big tip, and they said they will request me as their driver every time. I can't wait.
