Now who is the slut? (I) SeXStoRY

My girlfriend was out for her weekly girls' night and I used the opportunity to watch some football on telly and had a beer or two. Actually, it was just a friendly and pretty boring and I was getting quite tired. Anyway, I didn't want to go to sl**p before Emma got home. Sometimes, she would get a bit tipsy - a couple of times really pissed to be honest - from all the wine, so I used to be a bit worried about her walking alone from the subway late in the evening But this time, she had promised to leave together with Sally, her best friend, who usually leaves pretty early, arguing that she would have to be fit for school the following day and besides, she needed her beauty sl**p. Well, it's not long until graduation, so I guess she's got a point, though she's a bit of a nerd I guess. At least the beauty sl**p seemed to do its job. Blonde, slim and tall, with long legs and perky little breasts, she was a bit of an eye-catcher. Finally, I could hear the door open and saw Emma stumble into the living room, wearing a white shirt and her tightest jeans, showing the shape of her round little ass, one of her main assets. When she had taken her boots off, I kissed her goodnight, but she drew me closer and I could feel her tongue against mine. At the same time, I could hear my pants being unzipped and felt an eager hand unpack my half-erect cock. Within no time, Emma was down on her knees, sucking it as if there was no tomorrow. It didn't take more than 2 minutes until I was about to explode. When I wanted to pull out however, I could feel Emma's hands close around my buttocks, pressing me towards her and in that very second, my warm semen shot into her mouth, what a heavenly moment that was! After having milked me completely, swallowing most, she told me that we needed to talk. Drooling, letting the last drops run down her lips and drip down to the floor, I saw a glimpse of that evil-bitchy look in her eyes, which would normally make my cock grow in eager anticipation, knowing that she was having one of her dirty little ideas. She told me that on the way home, Sally had teased her again, telling her how slutty she looked, staggering through the streets in those tight jeans and high heels, her shirt exposing just enough of her boobs, leaving very little to the imagination. "C'mon honey", I told her, "she's just jealous of your perfect shape, that's all!" "Maybe, I guess you're right..but you know what?" - "What?" Emma came closer, as if someone was listening, hissing into my ear, making me feel her hot breath: "Maybe we should turn her into a bit of a slut like me!" Knowing how stubborn Emma could be once she got an idea, I knew that there was no point in trying to stop her. Then again, did I really want to stop her? Suddenly, I got pretty excited about the idea myself, so I suggested, "well, why don't we invite her over for a cosy movie night next week?" Emma's face lighted up instantaneously, forming into a sly smile. "That sounds nice, I'll ask her first thing in the morning." TO BE CONTINUED...
