That time I offered my boyfriend a 3way blowjob...

I was 18 years old and as a true redhead, I was crazy horny all the time. My first bf and I had been together for some months and I still couldn't keep my hands off him... Nor off my sexy colombian friend (I'm italian-venezuelan). I met her where he used to work and we inmediately clicked: we were both horny as hell all the time (scorpions, right?) and we were both bisexual, so there was not much we could do but experiment and enjoy ourselves and our bodies. My bf knew about that situation and he didn't care at all. Everytime me and my friend met, we went to the closest restroom and we started to kiss and touch each other; it was almost as if we were intoxicated by our passion, by our endless shared lust. She was a bit shorter than me, like 5' 2", tanned and with slightly bigger boobs than mine, which I couldn't stop touching, of course. As soon as we were alone, we took each other's shirts and bras and started caressing our breasts, licking and sucking each other's nipples. We also enjoyed putting them together as we kissed and seeing the contrast of my white skin and pink nipples against her tanned complexion... Our hands desperetely trying to find the way down to our underwear, shivering and trembling as soon as we touched our already wet pussies... So, one day, me and her were talking about fantasies we had and I told her I would really like to give my bf a blowjob with another girl. I mean, I love blowjobs, and the idea of doing it with another girl as we kiss and touch each other, seemed so hot that I just had to do it... She agreed to it and we did it that same day, as soon as my bf had his first break at work. He worked at a store in a tiny mall downtown and it was usually pretty empty, so we went to the top of the entrance stairs, where we could hear if somebody was coming up or down with enough time to hide what we were doing... We both grabbed him by his hands and took him there, as I whispered to his ear what we wanted to do with him. He nodded, so I put him against the wall, kissed him, kissed my friend, they kissed and we got down to our knees as he stood there silently, in total shock. He couldn't even speak, he was just staring down at us, so surprised about the whole thing... We unzipped his pants and took out his cock. It was already starting to get hard, so I put it in my warm wet mouth and felt how hard his cock was starting to get. I do love that feeling... I took it out and grabbed her head, so she started to kiss it on one side while I did the same on the other. Our tongues were slowly covering his cock, making it all slippery and wet, just like I wanted. We were taking turns to put his cock in our mouths and suck it, while the other one played with his balls, using our hands or tongues. We both lifted our shirts so we could touch our boobs and slap his cock against them. He was still silent and staring at us, just moaning as quiet as he could. I got up and started to kiss him, as he touched my breasts and my friend sucked his cock in a very slowly way. I kept looking at her for a couple of minutes but I just couldn't resist anymore, so I got down on my knees again and started to jerk him off as I kissed her again; at this point, we both seemed desperate, out of our minds with lust and pleasure. I put his cock inside my mouth again, going all the way down to my throat, as far as I could. As I began to choke, she was licking and sucking my bf's balls and I could feel he wanted to cum, any second now. His throbbing cock was making me so wet too, I couldn't wait for him to cover our faces, mouths and tongues with his deliciously hot cum. And then, out of nowhere, he told us to stop, just stop. I looked at him, then at her, just shocked about what was happening. I couldn't believe it, nor my friend. He zipped his pants and told me it didn't feel right doing it with somebody else besides me, his girlfriend... I clearly remember telling him "but I'm here and I want to do it!!", but that was it, he changed his mind in the middle of it... Nothing else happened between the three of us... It's been like 15 years since that happened -I'm no longer with him, of course!- and I still can't believe a man rejected a blowjob with two women..!!
