Head For The Head Of HR

I am a 52 year old married man with kids. I'm a big guy, not in great shape. On the order of Mike from Mike and Molly. Anyway, I've been a manager in the Transportation industry for 20 plus years. I just started a new job at a national trucking company. My job tends to work a lot with the head of HR. He is a well put together dude. Good looking. Ok shape. So, we've been working together and he keeps dropping subtle sexual jokes and innuendos. Today we were in his office getting ready for an audit and he says to me "You've been doing a great job! You're going to go places here!" As he's saying this I see him caressing his cock through his pants. He sees me looking at him getting hard. He then says "Let's see how far you will really go!" He stands up and unleashes his beautiful cock. I'm a straight dude but I even have to admit that it was perfect looking. He came over to where I was sitting, sat on the desktop in front of me. He put his hand on the back of my head to pull me in. At first I resisted but he thrust his hips up towards my face. I got a whiff of his manly musk. Once I smelled him I instantly got hard. I opened my mouth and guided his 6 inches or so into my mouth. God it tasted as perfect as it looked! My mouth began to water and my throat began to relax. This is the first time I ever sucked a real cock. I've fantasized and practiced on dildos or vegetables before but this was real flesh sliding through my lips, over my tongue and down my throat. He moaned like he was getting the blowjob of his life! I started to massage his balls while he continued to fuck my mouth! I was so turned on!!! I wanted him to cum in my mouth!!! I slid a finger into his ass and began to massage his prostate. He started to curse and groan. "You really want my cum don't you?" He asked. I tried to say yes with my mouth full of cock. He put both hands on the back of my head, forced me down, and thrust hard into my mouth, hitting the back of my throat. "FUCK!" He screamed as he began to pump his entire load down my throat. I felt like such a whore but I loved it! I've always loved the taste of my own cum and his was even sweeter! Once I was done, I looked up at him and he smiled. He then told me to sit back because he wanted to watch me jerkoff. I did as I was told and it didn't take long for me to explode all over my hand and stomach. He told me to clean myself up. I licked all the cum off my hand and fingers. He said "You got some cum on the corner of your mouth." He leaned in, licked it off and then kissed me! He then said he was going to put in a promotion for me to be the his assistant with an increase in pay. He said if I accept then we may have to do this a lot more often. I just shrugged and said ok and signed all the paperwork! Next time I want to bend over his desk and have him fuck my ass! I'm a virgin back there but I really want him to cum deep inside of me! Until next time we're alone.
