An Unexpected Encounter in the Office

Finally happed pt. 2. He didn't even answer me, just smiled real big as he pushed his cock all the way back into my mouth and throat. Now he used both hands on my head and was fucking my mouth with long fast strokes that were getting shorter the faster he went. His cock head was inside my throat pumping for a good while and I needed to get some air, so I back off to where his cock was only in my mouth and took a couple deep breaths and let him go back to work. It didn't take but a few more stroke and I felt his cock swell and his grip on my head get tight as he started shooting stream after stream down my throat. Feeling his cock pulse inside my throat was incredible I wished it didn't have to end. But his whole body started to jerk along with the last few pulses of cum being shot into my mouth.
I knew he would be sensitive, but I wanted to feel what I had just felt inside my ass, so I kept him in my mouth and slowly moved him in and out. We did this for a few minutes and I started feeling his cock getting harder again at the same time he started pumping it in and out of my mouth again. We did this until he was fully hard again.
He pushed me off of his cock and said that he would get really hard again as he ate my ass. I didn't waste anytime, I got up and went to my desk and bent over it with my ass sticking straight up in the air. He followed me and dove in tongue first. He was a master at tonguing my ass, it felt like little bolts of lightening as he penetrated me with his tongue. He worked in a couple of fingers and was getting me stretched open in preparation to take his big cock. I took some lube out of my desk drawer and reached under and put it on my ass as he took the bottle and covered his cock really good.
I was in heaven as he put the head up to my ass hole and pushed in, it hurt so good. He slowly worked the biggest cock I had ever been fucked with before until he was balls deep. As he started fucking me with long slow strokes I couldn't help but moan real loud and yelling fuck me with that big black cock make me your bitch, you own my ass, it feels so good!
He was loving it and was fucking me with long powerful strokes, he would lift my feet off the ground every time he hit bottom. He kept fucking me for a good 5 or 6 minutes before he told me he was getting close again. I told him not to stop, keep fucking me until you breed me deep. He pulled me closer to the edge of the desk and went to town, and at this angle he was hitting my prostate just right. When he announced he was cumming, I started cumming all over the side of my desk without even touching my cock. He was pushed as deep as he could get as his cock pulsed over and over again planting his seed. My cock was pulsing in Unisom with his. It was the most intense sexual feeling I have ever had. When he stopped cumming he pulled out and the cum gushed out running down my balls and leg. My ass felt so empty without his cock. I pointed him to the bathroom but I didn't move I was still bent over my desk. He came out fully clothed and said that he would love to stay and play more but he had packages to deliver. I told him we had to get together again soon. He wrote his number and email down and told me to contact him anytime I needed a good fucking. I will be contacting him tomorrow when my wife goes into work again.
