I checked on my girlfriend one more time- she was sound asleep. Her shift at the bar wiped her out, she didn't even get up after our quickie.
She laid there with her ass up, her cheeks red from where I thrusted against her.
My cock straightened, more due to the thought of where I was about to go than the site of her freshly fucked pussy.
I gently closed the door to my apartment and tiptoed down the stairs. My cock stretched my shorts out in front of me. Two girls coming home from the bar walked past me, and before I could cover it they saw my bulge and giggled.
I put my head down and ran across the street. My face was flush and my heard pounded in my chest. Only three hours ago I had only thought of touching a cock, now here I was going back for round two.
This guy, I didn't even know his name, got me to do things I never thought I would. The nerve, shoving my mouth down to his ass to lick his dirty hole, and holding my head while he used my mouth to catch shot after shot of his load.
Now here I was, with his cum still warm in my belly and the stench of his ass crack spread across my face, heading back.
I pushed my cock down, trying not to make it so obvious, by my gym shorts didn't stand a chance. It stuck out for all to see.
I told myself I was only going back because he had pictures. Those pictures could wreck everything. He threatened to show my girlfriend. He was blackmailing me, I didn't want to do this, I wasn't a cum craver.
I tried to convince myself, but my erection gave it away. I wanted to do this again. He didn't need to blackmail me, but that made it even dirtier.
I reached his door and pushed it open, just as I did only hours ago. I had gone in curious, and had come out a different person.
What was in store for me this time?
I crept in and whispered "hello?"
"You're awfully shy for someone who stuck his tongue up my ass hole," he laughed.
I cringed a bit. Hearing myself described like that would take some getting used to. This guy had used my face, humiliated me, and now he gloated.
But he had pictures, I had to comply. Again, I tried to convince myself that's why I was doing this. It couldn't be that I wanted to, right?
I walked halfway across the room and he stopped me. "Hold it. Take your clothes off."
I paused, still looking at the floor to avoid eye contact.
"Now."
"Why?" It was an honest question, I thought I would be blowing him again and leaving.
"Because I told you to. Unless you want me to show your girlfriend why your tongue tasted funny last night."
Again I felt a sting, but he was right. I lapped up his ass hold and wanted more, I couldn't take that back.
"OK." I said as I pulled of my shirt. I looked down, my cock straightened even more and felt like it was going to rip through its skin.
I pulled down my shorts. The waistband pulled down my head before releasing it to spring back up.
"Turn around."
I did so without protest.
"Hands against the wall, and push out that ass."
I reached for the wall, and arched my back. He didn't say anything as he stared at my ass and stroked his cock. This was more humiliating than having my face held in his ass cheeks. I had nowhere to hide, no privacy, just my ass sticking out for a stranger to gawk at.
"Pull apart your cheeks."
"I...don't want... why? What does this have to do with giving you head?"
"Shut up and do it."
I reached back and pulled my ass open. I could actually feel a draft, my ass had never been this exposed. My sphincter tightened, then relaxed a bit. What was this guy doing? He was just staring at me, pulling on his dick. Maybe I would get off easy and he would just jerk off and send me on my way.
"Wait, didn't I tell you to bring a pair of your girlfriend's panties?"
"Yes, they are in my pocket."
"Give them to me."
I handed them to him, and he spread out the crotch. He brought them to his face and took a deep breath. "mmmm, nice. She wear these at work?"
This guy was sniffing my girlfriend's pussy. I'm not the violent type, but I get jealous when guys check her out, now he was comment on her cunt's scent. My head bowed slightly in shame. "Yes."
"I can tell, she must sweat, it's nice and ripe." He took another deep breath, then handed them to me. "Put them on."
I didn't bother to argue, he would just bring up the pictures. I pulled them on, and the thong split my ass cheeks. It felt weird, like I had a wedgie. The front failed to hold back my cock and sock, which stuck out from all sides.
"Skimpy little underwear, huh? She a dirty girl? She looks like she could be, I bet she is a great fuck."
Again, the comment stung a bit. I guy was talking about fucking my girlfriend while I stood in front of him wearing panties.
How had this happened?
He was right though. My girlfriend was a bit wild, and had a sexual history that made me jealous. I know she sucked off a few guys in her neighborhood in high school. They would have her over after school, and at least two but up to six guys would be down there and she would blow them all. And she had had threesomes, including girl only. She also liked anal, which I wasn't big into. To be honest, it kind of bothered me that she liked it. It didn't like the idea of my girlfriend being dirty. How weird is that? I had a girl willing to do anything, and I wanted her to be boring.
She was just more sexually adventurous than me.
Until about three hours ago, that is.
Now, that doesn't mean I was bad in bad. In fact I know she had told all her friends how good I was. My cock was a good size, and I liked to pound. Maybe I was a bit vanilla, but I could throw some dick.
"You just fucked her, right?" he asked.
"Yes."
He leaned forward on his couch and grabbed my cock.
"Wait!" I yelled as I jumped back.
"What is your problem?" he demanded.
"I've never had a guy touch my cock before, I didn't think you wanted..."
"I couldn't care less about your cock. I want to taste her pussy. Now get back here, unless.."
"Yeah I get it, the pictures." I said as I moved closer.
"You're catching on."
He pulled out my cock and wrapped his lips around it. I could hear him moan as he lowered his face down my shaft.
