Straight? Maybe not entirely... SeXStoRY

Ive always considered myself straight and I still do find women more attractive than men but I've always fantasized about sucking cock. One day me and my friend, who are frequently naked with each other, were playing xbox. He turned to me half way through and asked me "have you ever thought about sucking cock?" I went bright red and flinched at the question, my instinct answer was "erm...i dunno...yeah" I looked at his crotch and saw his huge boner bulging in his trackies, I touched it tentatively as he tilted his head back and moaned. The whole time I was stroking his enormous cock (at least 9 inches) I was thinking about all those times ive played with my asshole and then sucked whatever ive put in there. I pulled down his trackies and pressed my lips against his throbbing bellend. I felt his hands on the back of my head as i pushed my head down, only managing half before gagging. I looked up at him as he pushed down on my head, I wanted more. I wanted his cum. I wanted him to treat me like a cum slut. I had no idea where these thoughts were coming from but I knew I wanted to be used and abused. I took his pre-cum and spit soaked cock out of my mouth and asked him if hes ever thought about fucking a guy. His face lit up with excitment as he said "maybe once or twice" in a chuckle. He had recently had a tattoo and used KY jelly to rub over it and so he took it out of his school bag and rubbed it around my virgin asshole. It was cold and made me shudder. I felt the tip of his naked cock against my asshole, I knew from the porn I watched that you need to loosen up before anal. But I wanted to feel the pain, I wanted to feel his huge throbbing cock stretch me. I let him f***e himself in, only managing the bellend before collapsing in pain. He had done anal with girls and knew how to ease himself in, so he took it out and started to finger me. It felt amazing, his long fingers stroking my g-spot. Then he said I was ready, so I rest my head against the pillow and lifted my ass up. I grabbed the bedding as he entered me slowly but firmly. He slapped my ass as he fucked me. He pounded me for what seemed like an hour of pure pleasurable pain. I felt his cum fill me up and drip down the back of my legs. I collapsed and he fell on top of me, still hard and inside me. I rocked back and forth, his firm cock stroking against my g-spot, a stream of hot, thick cum flowed out of my throbbing dick. He pulled his cock out and pushed his fingers in, drawing out some of the cum and told me to lick it off his fingers. So I did. That's when I realized, I love being a dirty, little, cum slut whore.
