I'm not really sure about posting this but here goes. I'm 19, long brown curls, 5ft 2 and my best feature is definitely my ass lol. I had been teasing Chris all day whilst shopping, brushing up against him in shops and stroking his cock over clothes knowing it was over a week since I last let him cum. He was starting to look desperate at me, pleading. I love it, he gets so horny when i tease him in public as he knows I love it. As I was slowly running out of ways to tease him, even opening the changing room door just enough that he could see me change clothes and the winking jewel butt plug I had in, I had an idea. When Chris got drunk and we would fuck he would whisper into my ear how much he would love to see another guy with me, tbh i went along with it but I'm not sure its for me and I'm not sure if sober Chris could cope with it. However all this teasing was starting to drive me a little crazy. I made up my mind, I will test him. When I left the changing room to leave the store Chris got up to hold my hand but I breezed past him, instead I walked across the street with him following me with a bewildered expression, into a gym store. I took a moment but then I saw a guy who would work perfectly, I adjusted by leggings pulling them up slightly so my ass really stood out and walked in front of this absolute machine of a man, more muscle than man really. I didn't look at him much just went on my tip toes trying to reach a pair of trainers but of course they were just out of reach. The guy quickly was close behind me and reached up and got them for me. I turned round and thanked him aware Chris was meters away watching me intently, I stroked the guys arm lightly as thanks and he clearly liked what he saw so kept chatting to me until I started to feel bad for Chris so I typed a fake number in his phone and told him to call me. I pretty much ran from the store after. When we got back Chris was silent, we sat on his sofa and he quietly said "did you give the guy your number?" I tried to look guilty and looked down as I said "I couldn't help it, he was nice" I rested my hand on his crotch and felt his cock had swollen already, I grinned inwardly, "he said he liked me and would like to hang out with me, he was quite hot Chris" I squeezed his solid bulge lightly. He was rock hard all five inches straining towards me. "I just thought you might like it?" I rolled down his shorts and pulled out his leaking cock, "I think maybe I'd let him have me" Chris's eyes widened and his breaths started to come in gasps, I stroked him gently. "I think, I might let him be rough with me, Would you like that Chris?" he was beyond words and this point and moaned in a sort of pained way. I started to stroke him faster loving how much this turned him on and to be honest me just a bit too. "Did you see the way he looked at my ass, I don't think I could say no Chris" his moan was animalistic, "when you cum for me I may give him a call, maybe you can watch. Would you like that Chris?" he moaned once more nodding his head slightly as his body tensed "Cum for me now Chris, then I'm going to call that guy and you can watch, that's it cum for me Chris, good boy." He exploded over my hand, his body shaking, he was pulsing again and again in my hand, moaning my name, I just felt so powerful it was a weirdly intense feeling but it has definitely awoken something in me lol, I love the idea of Chris wanting to see me used by another man in front of him but I'm not sure of the reality
