He pushed me against the wall and fumbled with my pants. Turning me around to face away from him. I could feel his fat stomach pressed against me from behind and that familiar lump just bellow his belly.
He pulled my cock out like he always did, tugging it a couple of times to make sure it was all the way out and then turned me around and pushed me so that I was kneeling on some sort of box, with my legs spread slightly. Then he unzipped his pants and pulled out his cock. It seemed long and huge and this time he rubbed it all over my face, leaving a trail of sticky wetness on my skin and in my hair. Then he pushed my mouth open and tried to force himself inside. I tried to open my mouth all the way but only part of his dick would fit into my mouth. He was just too big. This seemed to frustrate him and he tried to push deeper but there was nowhere to go. He grunted and squirmed and became very rough because he really wanted this it seems. At one point he pushed so hard it slipped to the side and I thought it would rip my cheek open. He shoved his cock harder against the roof of my mouth but I just couldn't open wide enough. So instead of fucking me in the mouth as I now know he was trying to do, he just held my head like that, his cock pushed in as far as it would go, and jerked off into my mouth. Holding the back of my head with one hand to keep me in place and jerking himself off, making a sort of gasping, whimpering sound as he did it. It reminded me of a dog. I'd never heard a human make a sound like that before and it frightened me.
I don't remember all of this very clearly, it was much like going to the dentist and trying to keep your mouth open wide enough and not swallow, which closes your mouth, Mostly I was trying to get enough air through my nose, but it started running and I could barely get any in at all which made me frantic. I had both hands pushed against his hips, but it didn't do any good, he was desperate by this point and kept his hard cock shoved in as far as it would go and all the while his fat hand rubbed frantically up and down it's length, banging into my chin and nose. The wiry hair on his hand seemed to be stabbing my face and it hurt a lot.
When he finally came, it filled my mouth in a rush and choked me and I gagged and coughed and all I remember is choking and gagging and his slapping me on the back until I quit.
I don't think I ever felt so completely helpless or desperate.
Yet despite this, for some reason I don't quite understand, I mainly remember the sensation of my own penis, bouncing and swinging back and forth out of the open fly in the front of my pants, and how lewd and nasty it felt.
I still often bend over like that and swing my cock around until it's hard and throbbing, and my favorite way to cum is still with my dick dangling down or in front like that. I like to let go and cum 'hands free' and watch it bob and jerk while it spurts.
