A Desperate Blowjob

There is a park down the street from my house where homeless people sometimes spend the night. There is a bathroom open 24/7, so its a convenient place for homeless people to wash and do whatever they need to when no one else is around at night. I met a homeless woman named Cynthia and after a few nights I convinced her to give me a blowjob for $20. This has become a somewhat regular thing for the past couple weeks. I will walk over to the park around 11 pm, sit on a bench and stroke my cock until she shows up. I fuck her throat, finish in her mouth, give her the money and leave. We don't even talk anymore. Well, a couple nights ago I was sitting on the bench stroking my cock when I realized that she was late. I looked at my phone and realized that she was almost half an hour late. I'd been edging my cock for about an hour and needed to cum soon. I waited about ten more minutes and then I walked over to the bathroom. I know an older alcoholic homeless guy named Kevin who sl**ps in the bathroom almost every night and I went to ask him if he had seen Cynthia that night. As I was putting my cock away, I got an idea which excited me. I decided to jerk off in front of Kevin to see what he would say. My heart was pounding from excitement. I was anxious to stroke my long thick cock in front of someone and I was so horny that I didn't care if it was a man or a woman. I walked in the bathroom with my hard cock in my hard, still stroking. Kevin is laying back on a blanket. He opens his eyes and it takes him a few seconds to realize what I am doing. I said, "Hey man. Have you seen Cynthia?" He looked at me jerking off and said, "What the fuck? Man, what a' you doin'?" I could smell the liquor on his breath from where I stood. This emboldened me. "I'm supposed to meet Cynthia here, but she's late. She usually takes care of this for me." I gesture towards my dick, which I am still stroking. "What?", he asks. "I pay her $20 to suck my dick. She usually meets me here and I was expecting her tonight." With that I stand there stroking my cock and looking away. "Yeah, well, I don't know where the fuck she is", he says, d***kenly. "Fuck. That sucks…" I say, still standing there and stroking. "Stop jerkin' off, man", he says. "What the fuck's wrong with you?" I was committed at this point. "You don't want to make $20, do you?", I blurt out, my heart pounding. "Fuck that. I'm not sucking your dick, man.", he says. "I'm not a fuckin' faggot." "I'm not a faggot either," I say. "But I was expecting a blowjob, and I need one so I can go to sl**p. I'll give you $20." "Fuck no. I ain't suckin' no cock, man." I reach into my pocket with my free hand and pull out all the money I had in there. A few twenties and tens fall to the floor. "Suck my dick and you can keep the money." He picks up the money and counts it. Then he looks up at my cock. "Man, what the fuck? Are you gay?" "No, I'm not gay. I'm going to close my eyes and pretend you are Cynthia.", I say. "Just suck it for a few minutes and you'll be done." "A few minutes?" He gets on his knees and looks at my cock. He teeters a bit. "This shits too big, man. I can't." "Just do it. That's a lot of booze money. You know I'm being generous." He looks at me, looks at my cock, takes a deep breath, closes his eyes and opens his mouth. He sits there for a few seconds with his mouth open, his body wobbling around, while my cock throbbed with my heart beat. I lean forward a bit and the tip of my cock hits his top lip. He recoils and says, "Fuck man, that's gross. I can't do it, man." "Then give me my money", I say. He doesn't look at me. He closes his eyes again and opens his mouth. This time, he leans forward very slowly and gently, until his mouth is around the tip of my cock. He sucks the tip a bit. His eyes are closed and he has an angry look on his face. "You can do better than that", I say. He sucks the head of my cock slightly, his lips frozen. The way he was going, I was never going to cum and in fact my hard-on was being to go flaccid. Without thinking, I put my hand on the back of his head and pulled it away immediately. I didn't like the way his greasy hair felt. I pulled down the sleeve of my jacket and covered my hand. Then I reached down and held his head while I pushed my cock into his mouth. He choked and put his hands up to my thighs to push me away and spat out my cock. "What the fuck, man!", he said. "What?", I asked. "What are you doing?", he asked, looking at me with bl**d-shot eyes. "Are you going to blow me or what?", I asked. "What you were doing is not a blowjob. I'm paying you to suck my dick, not just the tip." "I don't want you shoving your dick in my mouth. I don't like that shit, man." "If I don't shove my dick in your mouth, I'll never cum and you'll be sucking my dick all night. Is that what you want?" "Fuck!", he says. "Just don't fuckin' cum in my mouth, man." "Whatever", I say, grabbing my cock with one hand and holding his head with the other. He closes his eyes as I guide my cock into his cold mouth. He immediately makes a gagging noise and pushes my thighs again. But this time he keeps my cock in his mouth, and when I push his head forward, he doesn't resist as much. Must be thinking about the money, I thought. Good. I pull my cock out of his mouth, step back, unbuckle my belt and drop my pants. Then I step forward and resume thrusting my cock into his mouth in long slow strokes. He gags with every thrust and I don't like the way his beard scratches my thighs each time. Kinda turns me off and makes my hard-on falter. I thrust harder in an attempt to achieve orgasm quickly. This time he pushes me away hard and leans forward, coughing and spitting on the floor. "That's enough", he finally manages. He is panting and there is snot running out of both nostrils. "No more." "I'm almost done", I say. "One more minute." "I said you're not cumming in my mouth", he says. "I know." He closes his eyes and opens his mouth. I lean forward and shove my cock in his mouth. I replace my hand on the back of his head to steady his rhythm and for the first time, he is giving me a decent blowjob. My cock is sliding in and out of his mouth steadily, and saliva is running down his chin. He isn't gagging so much anymore and I'm thrusting at a steady pace. After about a minute he pulls away, breathing heavily, and reaches up instinctively to grab my cock. When he does, he seems to recoil and drops it again. "Fuck, your dick's big", he says. "What the fuck". He grabs it again and tries to jerk it with an awkward rhythm. "When are you going to cum?", he asks. I start jerking my spit-covered cock and holding his head with the other hand. "Don't cum on my face, man", he says. "I won't", I say. I figured then that he just wasn't going to make me cum. After what I paid I was determined to shoot my load in Kevin's mouth so I jerked myself right to the edge as he sat there panting. As I got close I pushed his head forward and shoved my cock in his mouth. I knew this was my only chance, so this time I put both hands on his head, ignoring the greasy hair, and began quickly thrusting my rock-hard cock against the top of his throat. He began gagging and groaning angrily around my cock but I ignored him. Feeling myself approaching climax, I started thrusting deeper into his throat. I felt the tip of my cock pushing against something which suddenly gave, and the rest of my cock slid into his throat. It felt amazing and at that point I ejaculated. I felt a few spurts and then Kevin was pounding on my thighs and pushing me away. He spat out my cock and bent forward, retching and choking. As he was ramming his fingers down his throat trying to throw up my semen, I finished my orgasm right where I stood, ejaculating on the back of his head and neck. I finished, put my cock away, walked home and went to sl**p.
