____________

Recently divorced, I started going to the gym to occupy some of my free time. I started with cardio and feeling around the weight machines, getting reacquainted as it's been a while since I've had a routine. At 36, I wasn't too out of shape and the stress of the divorce didn't ruin me too badly, just had some excess stress to release. The gym helps a lot. After a few months of getting back in the groove I found that the stairs were one of my favorite exercises at the gym, along with leg day. I noticed my legs getting stronger and my abs were getting defined and it motivated me to keep pushing.

My son Jason also goes to the same gym, sometimes I run into him, other times we'll go there together. Jason decided to stick with me after the divorce since my place is closer to the college he goes to. He's 18, athletic and already has a substantial build. He played sports all through high school and will continue playing football this fall. He's much taller than me, I'm only 5'6" to his 6'2". His build is more linebacker and I'm more swimmer. Both his mom and I were smaller but the men on his mom's side were all bigger guys, just like my son is, he definitely inherited the strong male genes on her side. Unlike his uncles, Jason never did make fun of me for my size and lack of height. Ironically enough, his mother seemed to love me regardless but she did leave me for quite the stud. Jason's been taller than me for a couple years now, it's weird that I have to reach up to him when we hug.

"Hey Jason, I'm heading out to the gym. You wanna go?" I ask as I peak into my son's room. He's relaxing in his bed only wearing basketball shorts without a shirt on, watching tv.

He looks up at me and tells me "I already went today but I could probably use another go. What are you working on?" He asks me as he gets out of bed.

"Legs." We both say at the same time before laughing. It's usually always legs. It's a more satisfying workout that I see quick results from, my upper body is already pretty toned and beach ready. "Can't have chicken legs when beach season rolls around again."

"Dad, you gotta skip it sometimes, give them a day to recover." He tells me as he reaches up and stretches out, I couldn't help but notice his strong muscles flexing and his long cloth covered cock snaking down his shorts.

"I do, you don't have to worry about me bud." I step forward to give him a hug, I stand on my tiptoes for the embrace and his hands accidentally end up a little lower on my back, accidentally grazing my butt cheeks.

"Oops, sorry dad. Woah, your glutes are growing as much as your legs, I haven't noticed." he steps back and turns me to face away as he lifts my shirt up.

I was just in my jock underneath "Uh, son I should warn you -" too late, his hand travels from lower back to my shorts and pulls at the waste band and starts to lower the back of my shorts. "Woah, yeah dad, you've got some major glutes gains." He confirms as my shorts sit beneath my mammoth cheeks.

He lets out a low whistle and says "You shouldn't be hiding these beautiful buns under all these baggy clothes, you gotta start wearing smaller shorts and tights that'll show 'em off right. That'll definitely get you a date and it's been a while since mom left, I think it's about time you do." he's palming each cheek now, feeling the muscles with admiration. He sits back on his bed for a more comfortable view while he palms my cheeks.

"I don't know about that son, I guess I'm still a little broken up about it. I'm not sure I'm ready to start dating again." It was weird having this conversation with my son while my ass is out and he's openly feeling me up. "Uhh, I'm a little embarrassed for wearing this jockstrap in front of you."

"Don't be, you look awesome. Besides, most guys are all wearing jocks anyway." I start to relax a little more as his hands are now spreading my fat ass cheeks apart, feeling the cool air on my hole each time he kneads my cheeks apart. "You got some dense, thick muscles here, dad. You're strong, all that time at the gym is really paying off. You know you gotta massage the muscles, not only stretching, to really let them recover. You ever do that?"

"I stretch daily but no, I haven't had a massage in what feels like ages." I admit, his hands on me felt really good, I haven't been touched in a while and no ones ever touched me like this.

"Here, lay down dad. I'll give you a proper massage." He tells me as he lightly slaps my ass and I get the chills a bit. He gets up and I take his spot on the bed, still warm from his body heat. I get a whiff of the warm, familiar smell that's only him. I feel him get up on the bed behind me and place his hands on each of my thighs and slowly start to massage them up. He was going right back to my butt.

I've always had a butt, not nearly as big as it is now but still a little large for my frame. A nice bubblebutt from years of swimming and good genetics helped too. Since I've been working out it's almost doubled in size and no one's gotten to check out these new cheeks. His hands back on my body and rubbing my booty, spreading my cheeks apart. I'm naturally pretty hairless, even my butthole and cheeks so his hands glide easily across my skin. I couldn't help but moan into his pillow at the incredible sensations my son's hands were giving me.

"Yeah dad, these are great. You look awesome. Let's move these out of the way though." He says as he slides my shorts further down my legs until they're off and he tosses them to the floor. "There, that's more comfortable." He says as he's able to spread my legs a little wider and sit between my legs a little easier.

He resumes palming my gargantuan cheeks, alternating between soft and deep pressure. I could feel my hiding hole winking between my cheeks and feel his breath on my skin, wondering if it was my imagination or if his face was getting closer to my ass. I hear him breath deeply a few times, I subconsciously match his breaths and relax into the massage. I can I feel his breaths land on my skin, tickling my senses and giving me goosebumps. He spreads my cheeks wide apart and exhale directly on my butthole and I know definitively that he's looking at it, front row seat to the show that is my puffy, pink rosebud. What was going through his mind? I tried not to be embarrassed, hopefully this isn't awkward for him, having his old man half naked on his bed. I can imagine the sight - both of his hands spreading my cheeks wide open while my pink rosebud is winking right at him while his breaths land closer and closer to my most private part.

"I've always been an ass man, dad. Most girls I've been with have had wide hips and a juicy, fat ass for me to play with." I was thankful I was laying on my stomach, hiding the erection that was growing first from his touch and now even harder listening to my son talk about the asses he likes while touching mine.

"How would you play with them, son?" I asked, low and breathy. As relaxed as I was, my heart was racing.

"Every way I could, I loved watching making their ass jiggle," he says as he makes my cheeks bounce and I feel my glutes shake. "They even liked when I slapped them." SLAP. I feel him slap one cheek, then the other. I involuntarily yelp and jerk up at the sudden smacks and then I moan back into the mattress. "I even enjoyed kissing them if I had the chance." and then I felt his fat tongue swipe right across my butt hole. The shock I was feeling was overshadowed by the overwhelming bliss from the sensation of a warm, wet tongue gliding over my hole. Over and over again he lapped at my hole, making me shiver with bliss. I couldn't believe Jason, my own son, was manhandling my cheeks and making out with my asshole. He move to my butt cheeks and alternated between softly biting and kissing them back and forth before returning to my hole.

His tongue was grazing over my hole repeatedly and I had never felt anything like it before. I moaned and grinded into the mattress as his face was being enveloped by my cheeks, trying to swallow him up. His tongue felt amazing trying to enter me, switching between kisses, long swipes on my hole and nibbling on the rim. I was in heaven.

As big as my butt cheeks are, my dick is the opposite. Unfortunately, I'm only almost four inches rock hard. Another physical attribute my son did not get from me. The size of my cock was the source for some of my exes and my bigger fights. Also my biggest reason of hesitancy when it comes to returning to the dating scene.

But right now with my son's face smothered between my cheeks, my lack of endowment didn't matter. He was, quite literally, into my ass. licking my entire booty, not missing a spot and not giving a thought about my tiny cock. I couldn't help but moan and squeeze the sheets.

He was becoming a wild man, devouring me like his last meal. I was loosening up and his tongue was easily gliding around, I was gonna need more of him inside of me soon, something I never considered needing from a man before.

I was leaking like a faucet and I haven't even touched myself, if I had known this act felt this good, this would not be my first time with a tongue in my ass. I was so hot for my son's tongue invading me and so disappointed when it plopped out of me. I look over my shoulder to see just what's the hold up was and that's when I see it.

Holy shit, he definitely did not take after me in the cock department. He looked to be about eight thick inches and it had me drooling from both ends.

"Wow son, that's a nice cock." I couldn't help but stare as my mouth watered.

"Fuck yeah it is." He slaps his dick into his palm a couple times, most of it flopping in the air around it, too big to fit in his hand. "Wanna feel it inside of you?"

"Oh shit." I was concerned, I'd never been fucked before, never imagined a cock that size even able to enter a tiny hole like I had. "Hell yeah." If a tongue felt that good, I was intrigued to find out how good a cock that size would feel gliding in and out of me. I was game to try a new experience.

"I'll go easy on you pops, I'll make you feel good." I was apprehensive but eager as he grabs some lube from his bedside table and slathers it on his cock. As he massages it in he leans forward to kiss my butt cheeks and nestle his face back between them to lick my hole a few more times. He then applies a generous amount of lube to my hole and has me move up to my hands and knees in preparation to take him.

"Alright, just relax and take me. Don't clench up, try and push back into me as I start to enter you." I feel his fat cock head massage my hole and I shiver at his touch. He starts to press into me and I feel a searing pain as this massive intruder invades my unventured orifice. He meets some resistance but slowly passes into my newly discovered hot, wet love tunnel.

We both moan as he glides in at a snails pace through my tight, moist anal walls. Slowly my body sucks him into me. I may not have consciously known this was something I wanted, but my body did and accepted him easily while the pain mixed with pleasure until it eventually subsided and I was overtaken by the blissful feeling of fullness.

I moaned, long and low as I finally felt him bottom out after what felt like forever. I never thought fucking could feel this good, now I realize I had been doing it wrong all my life. I leaned forward a bit and felt some of his cock leave me so I could lean back into him, that was a motion I could get used to. I repeated it again and again, a little faster and a little deeper each time. My mouth gaped open and my eyes closed, I tilted my head back as I gave in to the pleasures my body was feeling. My toes curled as my son started repeatedly pounding into me. We both start sweating as our bodies melted into each other.

"Oh fuuuuuuuck." I couldn't help but to moan out as my son bottoms out in me again and grinds his pelvis into my ass cheeks. Feeling me up with his hands, admiring my wide hips, fat cheeks and narrow waist. We were as close as ever and still I wanted to be closer. "Oh God, Jason, you feel so good inside of me."

"Damn pops, you're tighter than any girl I've been with. I had no idea you had this tight pussy waiting to be popped." I shiver at his words full of lust and approval.

"Neither did I. Pound my pussy, beat my guts. I wanna feel you cum inside of me." I was saying things I've never thought before but here I was on all fours, begging for my son's cock. I pinch my nipples as he pounds my prostate. Over and over, harder and harder, our moans intermixing as we approach our climax.

"Holy shit Jason, I think I'm gonna cum soon. Fuuuuck."

"Me too, your tight ass is squeezing the cum out of me, I won't last much longer." His long strokes gaining speed, nearly leaving me entirely before plunging right back in. I could feel the power emanating from his hips. My strong son and his thick cock overpower me as I submit to the newly discovered pleasures he's giving me.

Without touching myself, I moan at a pitch higher than usual as I experience my first ever anal orgasm and I feel the pouch of my jock fill with cum as I leak into it every time my son slams over my prostate.

"Oh shit, you're squeezing me so tight, dad. I'm gonna cum." I feel his cock getting even harder and the head swell as he pounds his blasting cock deep in my ass. Over and over again I feel seven or eight shots of cum explode deep within my ass. Jason keeps stroking inside me as we both come down from our climax. His stride slows down a bit until he stops moving but keeps his slowly softening dick inside me.

"Holy shit." He says as he wraps his arms around me and rocks us both to our sides, laying together and I'm the small spoon.

"Wow, I had no idea sex could feel like that." I said, breathlessly.

"Yeah dad, you got an ass made for it, you're a natural." My son reassures me as he grinds into me, his softening cock massaging my insides. "Still wanna hit the gym or does that count as a workout for the day?"

"I don't know if I want to work out now, I mean, that was definitely cardio but I still might need to work out my legs." I say as I enjoy the feeling of my son's big strong arms holding me close.

"I know a good way you could do some squats here at home. I'll just lay on my back and you can squat on my hard cock, I'll be hard again in no time." Jason nuzzles into the back of my neck, planting little kisses there. I can feel his breathe slowing as he relaxes against me.

"I'm always looking for new variations of exercise I like so I just might have to try that out." I move back into him and feel his cum sliding around inside of me, his cock still buried, preventing any of his cum to leak out.

"Oh fuck yeah, if you keep that up, I won't have a problem helping you workout soon at all." Jason grinds his hips into me, the subtle squelching sounds of our first fuck fill the room.

"Who knew all this time we had the best exercise available right here at home?" I ask as he tightens his arms around me and gives me a couple kisses on my neck and behind my ear.

"We may need to go for another round to test that claim. You know, for science or something." He agrees as he holds me in his arms and lightly pumps his now hardening cock inside me.
