SIR-NOW

I waited without making a sound watching my wife's father bending over to put the dirty clothes on the washer showing me his pucker. My cock reacted inside my tights and started to grow. It's been a while since I fucked a man's ass, a little after meeting my wife, but seeing my father in law in that position, arching his back and imagining how good that muscle ass must feel brought those urges back.

We had a very good relationship and were always joking so I decided to have some fun at his expense. I took two fast steps and slapped his ass hard.

"You know, when I said "make yourself at home" I never thought of this" I said laughing.

"You son of a bitch! That hurts!" Ted protested while rubbing his ass trying to ease the pain. You could clearly see I had left a mark. The shape of my hand was now tattooed in bright red on his left butt cheek. "You've branded me like cattle, son!" He kept protesting.

"You got a very slappable ass Ted. Don't blame me." He was still on his knees rubbing his cheek, his head almost at the same height as my package, when he saw my boner through my running tights. He widened his eyes with surprise.

"You obviously liked what you saw", he pointed out signaling to my hard dick. I blushed a little but got cocky and responded.

"Well, I haven't been gettin any since Abby got pregnant and I came home with your fat ass on full display. A man has needs, Ted" I put my hands on my hips and thrusted a couple times, making my bonner more apparent.

Ted licked his lips and smiled maliciously. He stopped rubbing his ass and moved his hand to his crotch tugging his balls and dick. "If you are so desperate, I prefer you to ask me than to attack me by surprise".

I was so horny. Watching him on his knees, his cock almost as hard as mine. I could see the lust in his eyes. I knew we both wanted this.

"Ted, if you're offering, I'm definitely asking".

"What are you asking for?", he asked as he traced the outline of my dick with his fingers.

"I want you to suck my dick" I said panting with anticipation. My father in law grabbed the waistband of my tights and pulled them down. My cock jumped like a spring and stained his chin with precum. He opened his mouth, stuck his tongue out and said seductively. "What's the magic word, son?"

"Please, I need you to suck my cock!" I answered desperately.

He suddenly looked down and expertly deepthroated me. A jolt of pleasure went from the tip of my dick through my back to the base of my skull. My knees almost gave up and I had to hold onto the washer and my father in law's head. He took it as an incentive and kept my dick there for almost a minute while massaging its head with his throat muscles. When he came for air my dick was coated in spit and he started fisting it vigorously.

"Jesus Christ Ted! When did you learn to do that?"

"I was in the army, son. We needed to have a pastime. But it's been some time, so I might be a little rusty. Let me practice a little more." After saying that he started to suck my cock with eagerness and passion. It was the best blowjob I've ever had. He used one hand on my shaft when it wasn't inside his mouth while the other traveled through my body. He caressed my abs, my pecs, pinched my nipples, grabbed my ass when he wanted my dick to go deeper. I was in heaven. I almost shot every time he grabbed my balls while he circled the tip of my dick with his tongue.

We went for about twenty minutes when I told him to move so I could eat his ass. He got up and we passionately kissed. Our tongues fighting to push into each other's mouths, biting our lips. Our hands roaming through our bodies, exploring the strong muscles under our sweaty skin. Then, he leaned over the washer, spread his legs and pushed his ass out. My mouth was watering with the sight that had started all of this, but now merely inches from my face. I grabbed each cheek and separated them. My wife's father's asshole appeared before me, hairless, winking, inviting. First I gave it a little kiss, and then i passed my tongue from the taint up making him moan and shiver with pleasure. I kept licking some more to watch it react contracting with every pass of my tongue. I couldn't wait any more and I started making out with it.

My father in law started cursing and moving, pressing my head from the back to make my tongue go deeper. After a while, I started to use my fingers and the first one got in easily with all my saliba around that hole. Once I got two inside, I decided to have some fun and surprise him. I found his prostate quickly and started pressing on it. Ted grasped and threw his head up after the first push. He turned to look at me and found my devilish eyes looking at him.

"What was that?!" He asked.

"That was your prostate, old man. Has your doctor never given you a prostate exam?"

"Yes, but never like this." He said panting. I never stopped caressing his prostate, now using both fingers alternately, like they were running over it.

"Well, you need a better doctor then. You can come by the clinic and make an appointment anytime." I was a GP and in times like this my medical training came in handy. My father in law didn't respond. He was only moaning and huffing.

I decided it was time for the main course and got up slapping his ass a couple times. I grabbed my cock, which was the hardest I could remember, and aligned it with his entrance. I gave it a little wiggle and without a warning I introduced it halfway through. My father in law took a deep breath and clenched his fists. I didn't move until he relaxed a little and then I started to push slowly. In no time I felt my balls touching his and looked down to see my cock completely buried in his hole. I took the opportunity to enjoy the sensation of the warm embrace my cock was feeling. I started to take it out and, when only the tip was inside, I pushed balls deep again in one stroke. My father in law had to stand on tiptoe after that attack and I hugged him tenderly. I started to rock back and forth and he started moaning. I grabbed him by the hips and piston rapidly. Then I changed speed and went slowly while reaching for his cock. He was rock hard and leaking like a faucet. I grabbed it strongly and kept fucking him. He whimpered and I knew he was about to finish.

"Let's go somewhere more comfortable so I can watch your face as I fuck you." I said.

"Perfect, but first, let me finish something." He picked up my tights, put them in the washer and started the cycle. I laughed while following him to my bed.

I pushed him over my mattress and grabbed his ankles. I aimed my cock at his hole and put it all the way in with one move. It was so used to my cock that I didn't find any resistance this time. I started fucking again. This time I could see his face having the time of his life. I could see every time my cock head pressed on his prostate because he made the cutest pout. I bent down and kissed him again. I kissed his lips while he moaned into my mouth. I kissed his neck feeling his accelerated pulse under my tongue. I bit his nipples making him scream with pleasure. Then I grabbed his boner and started to jerk it off.

I could see in his face that he was about to finish so I thrusted my hips as fast as I could to try and finish together. He opened his eyes widely and his face flushed bright red. I kept jerking him and then a thick rope of cum flew from the tip of his dick across his face. Then seven more shots landed over his pecs and abs. While his ass clenched my dick with each shot, I got over the edge and with one final push, I shot deep inside my father in law, coating his rectum.
