Bob my partner and I have known each other 15 years together as couple for 12. I can not remember the first time our paths crossed but Bob does it was an 18th birthday party, he looked over and a couple were standing in the corner snogging and the guy was practicly dry fucking the girl. After a few moments he pulled the girl outside and then he saw me, as a teenager I had very distinctive hair very long blonde almost white with a natural wave in it. He assumed we were going out for a shag as we had been so into each other. A few more times at either clubs or social events we had both been invited to he saw me and always with a different guy. When he recalled this to me after we moved in together I laughed I was very popular with the guys they knew I would wank them off and they could finger me. Bob looked a bit surprised at this but I explained it took me a while to have full sex I wanted my first time to be with an older and more experienced guybut as I realised from an early age that sex was an important part to my life went for mutual mastrubation which the guys liked while still trying to persuade me to go all the way. Bob of course asked me did I find my older guy I laughed oh yes I did a story for another day. We were in company a combined hen and stag night when I was properly introduced to Bob we hit it off straight away and we got a flat together soon after. The first time we had sex it was all hot and horny and I found Bobs cock was a little longer than other guys 8" fully erect and slim. I could not wait to get that inside me. Bless him he tried to be gentle because some women he had been with were never sure if they could take it. Me being my randy self grabbed it bringing it to my hole just fuck me Bob I am wet an slippy you will have no problem. Well he took me at my word rammed straight in and fucked me so hard I thought he was coming out my mouth. We came together me a high pitched squeal him a flood of hot spunk. Bob soon found out that every now and again I got restless and could not get enough of him no sooner had he fucked and I was sucking his cock to get him hard again, he calls it my bitch in season time. After one night of hot sex and we were geting our breath back he quietly said to fill this void that happens had I ever thought of taking another cock as well as him. To be honest I had never thought of it but as we lay there me fondling his cock hoping to get it hard again him fingers stroking my pussy and clit. We discussed it not against the idea of more cock but how would he feel at the thought of me being fucked by someone else. He said well I would be in the room as well joining in, oh even better. We decided to see how it would go by someone we trust and I know fancys me, Derek one of Bobs pals who we both knew at the drop of my knickers would be between my legs. We arranged for him to come to the flat one night a meal a bit of wine me in very sexy clothes, Bob made excuses to leave us alone a few times and I gave him a good view of my tits stroking the back of his hand as we talked. He got bolder his hand on my knee, his cock was so straining to escape his trousers. Bob came back put some music on I pulled Derek up and started to dance with him slowly my body rubbing against his, he kept glancing at Bob to see his reaction, Bob grinned at him. Dereks hands slid down my back cupping my ass cheeks now he was grinding into me his hard cock pressed against my pubic bone. I turned in his arms bringing his hands to my tits grinding my ass on his cock. Bob stood up standing in front of me he gave me a long wet kiss pulling the front of my top down exposing my tits he starting kissing them and Derek started to nibble my neck sending hot waves through my body. Bob looked at Derek and said I think our Lucy wants to be fucked, I led the two of them to the bedroom son we were naked and Derek was between my legs giving me such a fucking while Bob fed his cock into my mouth. The look on Dereks face as he fucked me he could not believe his luck. when we all came I gave them each a good sucking till they were hard again and then to my great pleasure they spit roasted me a first for me but not my last. This continued for the rest of the night till I could not get them hard again and we all fell asleep on the bed. I woke to Bob pushing me on my side as he fucked me from behind while Derek ran his cock up and down my slit till he came on my belly. This was our first forry into 3sums derek visited us many times but he got a girl friend who was not into 3sums or 4sums but we carried on to many adventures including on holiday once where 5 guys wanked and spunked over me.
