In my gym, there's a straight guy named Fred who has the sexiest, muscled ass I've ever seen.

I was alone in the steam room with him. We were both jacking off. He has a large 10-inch cock, but he looked with envy at my cock.

“Wow. What a whopper. That might do a girl some real damage,” Fred said.

“You're not small either and your build is larger than mine especially your butt," I told him. "That must be a big turn on for the girls.”

“Yeah, they love it," he agreed. "That's why I work especially hard on squats and lunges. Your butt is pretty good too,” Fred pointed out.

“Yeah it turns women on. They love to lick my ass,” I told him.

“Wow, no woman has ever done that to me. How does it feel?” Fred asked.

“God, it's awesome man. It really makes your cock stand at attention. You want to try it?”

“What do you mean? I’m not into sex with males, I'm straight!” Fred objected.

“Exactly! Since you're straight it doesn't turn you gay just because I eat your ass. It is just another way of enjoying sex," I reasoned with him. "Just close your eyes and imagine it's your girl doing it for you. After all, a mouth's a mouth,” I used the old lame excuse.

Damn, I think to myself, this has to be the dumbest jock on the block.

“Of course not," I led. "Just kneel here." I gestured to a two-tier padded bench. "Stick your butt in the air. Relax and let me do all the work. Keep stroking your dick.”

“Are you sure it's ok for two straight guys to do this?” he asked, unsure about all this, but he did kneel on the bench.

“Of course! I do it all the time with my buddies,” I assured him.

I knelt on the lower bench looking straight into the guy's crack.

Up close it looks even sexier – powerful muscles, tight under smooth white skin, two big round cushions of male flesh quivering, joined by a not too deep crack, at the bottom of which I can see the most fuckable virgin asshole, a rosebud ready for the taking. My mouth waters; my dick oozes pre-cum. I love to eat ass; and I really love virgin straight ass!

“Now open your buns for me. Spread them. Raise your hips so I can see the hole." Good, nice and clean, I note to myself. "I'm gonna give you a good tongue bath. Are you ready?”

“Shit, yeah, man. Let’s do it,” he agreed, uncertainty gone.

I laid my hands on his delectable butt cheeks and massaged them lovingly and then I pushed my face between his hot buttocks and stuck my tongue out, lapping around the hole. I drooled over his crack and slathered saliva all over his butt as my mouth rimmed his ass and my hands massaged his cheeks. He tasted fresh, like a baby and I ate him up. Damn, I love the taste and feel of young male skin and the firm, muscles underneath. He moaned softly. He was loving his first rim job.

“How are you doing pal? Can I go on?” I asked, knowing he was hooked.

“Yeah, don't stop," he said, excitedly. "Damn, it feels great. Is that how your women do it?”

“Well, they try to stick their tongue way inside," I lied. "Do you want to try that?”

“Yeah, why not?”

I inserted my thumbs on either side of his asshole, pried it open as wide as I could and shoved my tongue up his hole as far as I could. He pushed back to welcome me in. Not bad for a straight man. His tight hole squished my fat tongue and I again pried his asshole open using my thumbs. My lips were glued to the stretched borders of his chute. I started to wriggle my tongue. I moved it in and out, and hhe went wild, thrashing and moaning.

“Yeah man, eat my ass," he cried. "I bet those gay guys don't know how to eat an ass like you do.”

I eat his ass. My lips and tongue left no area of his butt or ass un-licked as I spiralled in and out, to and from his asshole. I glommed on to his asshole with my lips and sucked on it as if I could pull him inside out. I pull his asshole open wide again and work my tongue far up inside his asshole. If I’m not careful I’m going to shoot off just rimming him.

He can’t take it either. The next thing I heard is him saying he’s cumming.

“Fuck! I'm going to cum! Aghhhhhhhhh.”

He raised his torso up, pushing my face away from his asshole.

“I'm shooting," Fred cried. One, two, three, four spurts of cum spattered us both."Oh, fuck, I’ve never come like this before; fuck, yeah, man, I like that getting my ass licked while I jack off!”

He collapsed forward onto the bench.

"Do you have another load in you?" I asked. "Do you want to go for another blast?"

“Oh, shit, yeah, man! That was fucking good,” he proclaimed enthusiasticly

“Let’s try something else. This time it will be even better." I scooped up some of the cum that had spattered on the leather padding of the bench. I spread it on his asshole and fingered some in. "Feel that hot cream I'm sticking into your hole? It's your own cum that you just shot on the bench. Doesn't that feel hot?”

“Wow, that's kinky… Mmmm, good." He flinched as I pushed my finger in. "What's that?” he squawked.

“My finger," I said, soothingly. "Doesn’t that feel good? You have a highly sensitive asshole, you know. Nobody ever told you that?”

“Never. Is that bad?” the stupe asked.

“Well, it puts you at high risk of turning gay if you don't get the right treatment. You're lucky 'cause I'm an expert in treating sensitive holes with my special instrument,” I lied.

“Nothing! Just bend over, relax, and let me work. There might be a little pain but you’ll have to take it like a man, unless you want to turn gay,” I warned.

I couldn't believe that this guy was really this dumb. Of course, maybe he wasn't really dumb but just pretends because he found out he liked somebody eating out his ass, and fingering his asshole.

I kept working his hole with my finger, getting him nice and lubed up with his own cum. He was moaning again, wanking his flaccid dick, trying to get it hard again. I slid my index finger all the way up his ass and massaged his prostate.

“Oh jeez man, that’ feels fucking great! What are you doing? My cock just got hard as a rock again. Whatever you're doing, just keep on doing it,” he demanded, pressing back onto my probing finger.

He wiggled his ass, backed harder into my finger as I worked his prostate and moaned and whimpered.

I stuck one, two, and then three fingers up his ass and soon he was taking four. His sphincter was amazingly pliant and receptive. He was born to be fucked; he just hadn’t known it until now.

“Fuck, yeah, dude, I don't know what you're doing but I love that treatment," he coo-ed. "Thank God I have a sensitive asshole, otherwise I might have never have experienced this. It feels so good. I may even cum again.”

I place my cock’s giant head right on his asshole.

“Ready?” I asked.

“Yeah dude, just give your anti-gay treatment. As they say, no pain no gain.” he proclaimed bravely.

I pushed against his anus, his hole opened up, offering little resistance, then swallowed my giant dick head whole. He shuddered.

“Uh!” he gasped.

“Are you ok?” I asked, as if I cared.

“Huh,” he grunted.

I took that as a yes and shoved the rest of my dick up his ass. He was drenched in sweat, grinding his teeth and grunting. As he said, he'd do anything not to turn gay, including having his ass fucked.

“Huh. Uh. Huh. Fuck. Damn fuck. Huh.” He puffed, panted, swore, groaned and grunted, not knowing whether to scream or cheer.

“Easy man. Keep breathing. Breathe when it hurts. Breathe in, let it go, breathe out, squeeze. Damn, you're so fucking tight. How is it going?”

“Huh. Uh. Better now,” he grunted.

“Want me to pull it out?” I asked, knowing full well that he was starting to enjoy this foreign object inside him.

“No, I can take it,” he said bravely.

“Now I want you to work that big ass. Flex those muscles. Yeah, good," I told him as his sphincter closed round me. "Squeeze that hole.”

God, he had an incredible asshole. Not everybody is comfortable taking eleven inches of hard cock up his shit chute. I deep-fuck his asshole with every stroke. I put in all the way in and always gave it an extra push each time I bottomed out in his crack, and I kept my cock head in his ass every time I pulled back.

He really began to work his sphincter muscle, bearing down with some extreme pressure against my shaft. Obviously he wasn't hurting or he would have been trying to get my cock out of his ass instead of making such a valiant effort to keep it in his ass. I’d never fucked such a tight ass. The erotic sensations he wascreating in my cock and balls were awesome. I was ready to blow my load any minute.

“How does it feel having my instrument sliding in and out of your hole?” I asked him as I continued to deep-fuck him.

“It feels soooooo good, much better than before, as you promised. I love it when you're all the way in me. You're right, I gonna cum again, and it feels so good.” So he wasn't fooled by "my instrument." He knew it was my cock inside him.

He shot huge jets of semen all over the bench. His body convulsed as he shouted in triumph, “I'm cumming! I'm cumming!”

His ejaculation squeezes my cock so hard, I can't hold it either. I shot a huge load deep inside him.

I’d just pulled out of his ass when four guys I knew come into the steam room.

“Fuck! He won the bet," one of them exclaimed. Another cried, "He's fucking Fred’s ass." And a third cried, "He turned him from straight to gay just like he bet he'd do.”

“Wait a minute”, objected Fred, still kneeling there, with my cum dripping out of his ass. “This is not what it seems; I'm totally straight and he’s just treating my sensitive anus with his special instrument.”

Fred didn’t object. He just opened his mouth and the guy slid his "special instrument" into it. As I headed for the showers, I heard one of the guys say, “Oh yeah, Fred’s really gonna enjoy our special instruments.”

Just what I’d figured, I thought. It hadn’t taken much to get him to go from being staright to getting fucked to sucking dick. Fred wasn’t dumb; he had just wanted to be encouraged to be gay. He was really gonna have a sore ass and jaw tomorrow. Going to the gym was a fucking riot from that day.
