When I was a freshman in college, there was a guy on my floor who made me very uncomfortable. His name was Simon and he was tall, burly, and looked 30. It turns out he'd actually repeated a grade for sports and was a year older, but it seemed more like 10.
The reason he made me nervous was two-fold. For starters, he had a habit of looking at me funny whenever we were together. Whether it be a floor activity, drinking with the boys, or simply hanging out, I'd always catch him eyeing me, making me blush with hot nerves. Which brings us to the second reason I was afraid of him: raw attraction.
I knew I was gay but it was the 80s and the closet was safe. That still couldn't stop me from shivering with secret desire when I saw him on the first day. He was exactly my type: big, strong, always in his cowboy boots and hat like he was still in west Texas.... Damn, Simon was fine. But his big muscles only fueled my fear of getting caught drooling since he was a tough dude who could snap me like a twig! I tried to play it chill as we settled in but remained wary around him.
Our floor had a communal shower and one day me and the boys were having a rinse. Simon was there too, to my dismay, so I had to avoid spying his football-player body, lest I pop a boner in front of everyone.
While facing the nozzle and washing my hair, Simon called out, "yo, Matty, why'd you never tell us you have such a big ass!"
The boys all cracked up while I blushed profusely. Simon and I didn't interact much on account of my fear and this was one of the first things he'd said to me. How humiliating for it to be a comment about my butt! And on top of it all, he wasn't lying. I do have a big butt and it's always been a source of shame. I'd been made fun of for it before but thought those days were over.
"I'm serious, Matty," he continued, again calling me by a childhood nickname I was trying to drop. "It's like a girl's butt, all big and round. And barely a hair on there! Mine looks like a damn forest!"
He turned around to shake his thick, hirsute ass and everyone howled. I burned with humiliation but took it in stride, hoping to not look like a crybaby. My reaction seemed to work as everyone got over it; well, everyone but Simon. When we exited he wrapped his arm around my shoulder, an act that was quite intimate since we were both naked.
"I'm not kidding, man, that ass is something to be proud of. Matches that girly little dick of yours, too," he added with a sly wink. I dropped my head in shame because he was again astute.
"Awww, cheer up, buttercup, I'm just payin' you a compliment," he said while holding my chin in a joking manner. "Well, see you around, girly butt!"
SMACK
Before Simon walked away he spanked my ass harder than it ever had been, making it ripple like jello. The thunderous clap echoed through the bathroom and the stinging sensation remained for nearly two minutes. When I got to my room, I ran to the mirror and dropped my towel. Upon turning around I saw an enormous hand print painted across my entire milky buttcheek!
"Oh my god..." I shuddered while viewing it at different angles.
As I inspected Simon's print, my dick began to rise... I couldn't believe he'd marked me like that, branded his big hand on my naked flesh! It felt like it wasn't even my skin anymore, like it was his, and his bizarre comments in the shower only made me hornier. Even though I knew he was just teasing me like he did with everyone, the spank made it so much more lewd. I jerked off in front of the mirror while tracing over the red, welted lines, then spewed on the floor.
The following days were normal, but I couldn't stop thinking about my encounter with Simon; his big hands marking me... We still hung out in a group and they'd all forgotten about my fat ass--except Simon, of course.
"Those pants are a little tight, don't ya think, girly butt?" he asked while sneaking up from behind one evening.
He planted his meaty paws right on my cheeks and I jumped.
"Shut up, man!" I whined with a weak punch, tacitly accepting my new nickname.
"Whatever you say, girly butt!"
Simon didn't stop his teasing and actually ramped it up, finding ways to grope me whenever we were together. His constant touching was weird but it all felt like a running joke so I just let it happen. If he exited with a spank, which often occurred, I'd sprint to my room to check it in the mirror. Even through my jeans he would leave a faint handprint. I cherished them....
"Come on, man, quit it..." I begged at a party the next weekend.
"Just another second, Matty, not much longer."
Simon and I were in the kitchen grabbing drinks when his roughhousing got more aggressive than usual. He pushed me up against the sink and his hands went straight to my buns, where he started squeezing and kneading.
"So big...." he muttered.
"Come on, dude, cut it out!" I pleaded.
We were both drunk and I didn't know if this was just another one of his games.
"Don't get all bitchy with me, girly butt. I'm just giving you the attention you deserve."
"Duuuude, that's enough. Pleeease...."
My dick swelled as Simon drunkenly humped and groped me. I got nervous someone would see and was also afraid of my own homosexuality, so I tried squirming away but he cut me off.
"Don't ever pull away from me!" he ordered sternly in a tone I'd never heard. It scared me.
"Okay... sorry..." I whimpered in defeat, aware he could easily overpower me.
"Good boy."
I stood pathetically and allowed Simon to fondle my butt for another minute before he grabbed us two beers. He then wrapped his arm around me and walked us back out to the party like nothing had happened.
My memories of his actions were hazy but I knew something weird had occurred. I wasn't yet too afraid to be around him, but was now on guard whenever he was nearby. In the showers though, nothing could protect my naked butt from his greedy paws.
"Didn't think I'd see you in here," Simon smirked as he sauntered into the bathroom.
I'd been enjoying my privacy but now was completely on edge.
"Calm down, I'm not gonna hurt you," he said genuinely, clearly noticing my nerves.
I appreciated his kindness and went back to washing myself. Forgetting who was across from me, I turned to rinse my hair. Big mistake.
"Ooooowee!!" Simon whistled when my rump was in full view. "Now that's a peach right there!"
I blushed and quickly turned back so he couldn't see.
"Oh come on now, baby, don't be shy. Let me see that big ass of yours. There's no harm."
"Dude, cut it out...." I muttered, if only to put up my usual front.
"Come onnnn, just a peek," he winked cheekily. It was sort of cute how badly he wanted to see it.
