I was 18 and had been in the army for about 8 months when I got a guard duty with my Corporal - Bob. Guard was usually boring - apart from occasionally wandering around checking the base, we watched movies. Around midnight, Bob put on a straight porno - he told me his wife did not like them, and this was about the only time he could watch them. Being 18 and constantly horny, this was fine with me - although I can remember this sounded a little strange, given that Bob and his wife were "known" to host erotic parties.

After a while, Bob put on a bi video, and a little later took out and started playing with his average-sized cock. It was not the first hard cock I'd seen, having blown an 'uncle' and sometimes one of his friends till I joined the Army. I had found that I liked sucking older men. Bob was in his early 40s, with a bit of a belly and as it turned out a lovely cock - average (6 inches) and not thick - which he knew how to use well. Soon he told me to take out my cock, which he said was lovely. Then while I was still coming to terms with seeing my boss playing with his hard cock he reached across and started to stroke me, and soon I was stroking him. It felt great, but I was 18, fit, always horny and had not sucked cock in months. I wanted more.

Bob then, without taking his eyes off the movie, told me to strip and stand in front of him, I couldn’t wait. Soon his hands were all over my body. I loved it as he slowly took me in his mouth and started playing with my ass. One of his fingers found and then entered my asshole. It felt so good. His first finger was joined by a second as he sucked my cock and slowly widened my ass. Then he stopped sucking and told me to get down on my knees. I enjoyed being sexually submissive, and did not hesitate. He was hard before I took him into my mouth, and I tasted his delicious pre-cum straight away. Bob moaned and called me his little slut and whore. My mouth began to be fucked by Bob, and he moaned louder as his cock touched the back of my throat.

“Nice, nice. You sure have got sweet lips," Bob kept saying as he thrust in and out. I loved every moment and expected to swallow his cum at any moment when Bob told me to stand up and a gave me a passionate kiss as he inserted a finger once more into my ass. Loving it, I gyrated on first one finger then two until he told me to turn around then started to rim me, I had been rimmed before but not like this - Bob was passionate and as I soon found out wanted to put more in me than his fingers and tongue!

"Cute ass - have you been fucked before?" Bob asked. "No," I said - enjoying his fingers and beginning to imagine his cock pounding me. “Would you like to?" I said. Bob put some lube on his cock, told me to bend over and grab the desk and then slowly his fingers were replaced by his throbbing cock. It was my first, there was some pain (especially at first), but it also felt sooooooooo good. Soon I was moaning and begging for him to fuck me harder.

He did, grabbing my ass; slapping it; calling me his slut. Every moment was bliss. I had wanted this for so long.

After a few minutes that seemed much longer, Bob roared out and started to cum in my ass - still stroking and moaning until he became soft and pulled out. He told me to turn around and suck his cock, and I happily slurped and swallowed what cum he had. He told me to stand and kissed me for the second and last time. "Did you like that, slut?" he asked. I nodded, but he said he wanted to hear the words and to remember to call him sir. My legs were shaking. I was tingling and sore in new places and wondering about future fucks when I told him, "Yes, Sir. I loved the feel of his cock fucking me." "Good," he said; “Now get dressed, Slut. I may fuck you again later if you are lucky." He did not - but he did invite me to stay at his place for the next weekend and I happily accepted. I could feel his cum dripping from my ass; I was sore but elated, and eager for more!
