Do you go to the session with Betty?
You’re already here
You lay there a minute, gathering your thoughts.
“Hey, you awake?” You hear someone ask.
You look over and see a tan-skinned blonde at the end of the bench you are laying on. “Yeah, sorry, just thinking.” Everyone else appears to have cleared out.
“I actually thought you were a pregnant girl for a minute before I came closer. Your girlfriend there just left you to like fend for yourself getting dressed.”
“I appreciate that. All of it, thank you! I was about to join her in the ass workout class, but the afterglow kind of gave me the lazies.”
“I’m going there too!” She turns and flashes pulls down her thin pants and shows off her bulging bottom. “It really works if you want a nice big bottom. But you gotta eat a lot too ‘cause you need fat to fill it out and make it round.” She spins back and you see her belly has a little paunch. You also see her erect cock.
“That’s nice…” you stare at her.
“Which, front or back?” She giggles and turns and trips over her pants around her ankles.

Hello! Sam here again! Look, the author wants to make everything seem all random, but this girl, Wanda, didn’t ‘trip and fall into me’. She stumbled like an idiot and righted herself and I told her I liked her dick. She asked if I wanted to- I cut her off by hooking my heels behind her thighs and pulling her towards me. Like Betty, she only took a like a minute to cum. Unlike Betty, she had the common sense to help me dress, teasing me the entire time about being pregnant, which she got the idea I liked. She even joked about ‘trying again’, to which I didn’t turn her down!
So I’m just going to…delete whatever else the author had here…and bring us to the workout! Enjoy! I know I did!
+++++
You enter the classroom with Wanda and you take a spot right at the front of the class, not really wanting to show off the belly to everyone. The instructor walks in. A dark skinned guy with a huge bubble butt that was out of place on his otherwise trim and fit frame. He stops by you and offers his hand.
“I’m Blake, welcome to my class. Don’t get many guys in here.”
“I’m Sam. Looks like you are the walking advertisement, though.” You take his hand for a quick shake. He eyes you up and down.
“Maybe we have the same taste in women? With a little extra?” He directs your gaze to the woman that would be directly in front of him once he starts the class. You see her non-erect cock is bulging her pants leg down to her knee. She winks at you two looking and adjusts her cantaloupe-sized balls and pats them.
“Maybe with more then a *little* extra,” you agree.
“Seems like you came to the right class,” he chuckles. “We’ll help you get there. You’ll be more fat than muscle at the start, but after a few months you’ll get the muscle too. Oh, and when it’s time for a partner, you’ll be in high demand, just a fair warning.”
“Hello class! Welcome back to the best ass workout you’ll ever have! Let’s begin our three hour grind…”
*****
Your ass is exhausted. Your belly is coated in sweat and your clothes are drenched. And you still have an hour left.
“Good job so far everyone! How’s your ass feel? Mine feels great! So great I think I need a cock in it! We also have another guy today too that said he’s into the girlcock. Sam here is ready to get his ass pounded and tenderized! Tell ‘em Sam!”
You are a little surprised, but roll with it. “Hi ladies, I’m happy to be here. Betty didn’t mention the…uh…” You see the lady right out front pulling her pants down for her growing erection and winking again, “…big juicy cocks I’d be playing with.” You peel off your pants. “I’m kind of excited though!” You kick off your pants and see a line behind you, and Blake already taking one in the butt.
“Great, Sam! My bottom thanks you! Maybe I’ll walk out of here normally today!”
“I’ll go last,” the lady with the very large and thick cock tells you. “I’ll give you a helluva cream pie. Probably two if you want a real workout.” She eyes the first girl that already blew her load in you street thirty seconds. “I’m pent up too, but I’ll treat you right after we get the quickie out of the way.”
*****
You spend the better part of the hour as basically a cum dump. Blake even excuses himself with a heartfelt thanks in his eyes, as you have most of the attention. Betty and Wanda last longer, but the rest are quick.
“I’ll text you my address,” Betty says with a wink. “Take your time, I’ll need a few hours to make dinner.”
“I’m Janelle,” the big dicked girl introduces herself. “You are probably all warmed up for me now, but fair warning, you are going to walk funny for a few days.”
“Funnier than I do now with this?”
“Yeah, you are going to look like you are pregnant *and* that didn’t quench your thirst for this big cock!” You blush. “I didn’t see your face turn red after getting naked and taking nearly every dick in the class, but now that I tell you that you look nine months pregnant with twins…you like that? Just not fat by accident, huh?”
“I don’t kiss and tell,” you blush deeper.
“Smart guy. Too many people on social media these days bragging about their lives. This fitness club is not exclusively for girls like us, but if you aren’t into it, you quickly figure it out and move on. There’s no advertising so we can be ourselves without drawing attention. Also, a great spot for finding a partner for the night or longer. We aren’t opposed to sharing, and we have a strict in-network policy for sex to prevent STDs. Your doctor must have cleared you for you to be in the class.”
“Must have,” you shrug. “I have a dinner date, can we get started?” You playfully swat her cock and laugh.
“Do you have breasts?” She asks.
“Does it look like I do?” You shake your sports bra clad chest, which you also keep hairless. Your overindulgence increased your bra size to C cups over the past few months. “It’s just fat,” you giggle as she seemed surprised. You raise up and catch her cock into the hem of your top and push the shaft between your shaped mounds. “You want me to fuck you with my titties?”
You open your mouth as she pushes deeper and catch her cock and suck. It’s so long you can suck her off and titfuck her at the same time.
“Just a quickie, remember. It’ll only take a minute…”
You catch her cum and swallow. You see her balls flexing and get a pace going and don’t miss a drop. When she stops, she pulls back, pulling your top over your breasts.
“Those actually look kind of like real breasts,” she mentions.
“You think? Yeah, they do now…”
“Wear those tight tops and they’ll shape your body over time. Can’t let them out too often or they’ll go back. I want to hear them clap together as I fuck your ass though.”
You didn’t need another hint and are on your hands and knees with ass up in the air. You look back at her. “Well?”
“Going to give me a second to breathe? I guess not…”
She guides the thick shaft between your cheeks and the cum-slickness from the earlier fucking helps her stretch you smoothly. You welcome her cock inside gradually; she knows the perfect pace for her size. She could go a little faster. You did just fuck like the whole class.
You push back a little and you open wider and she stops and lets you take control. “Go ahead,” she encourages you.
“Just need it deep inside,” you explain and push back further until she gets you wide enough to slip inside. You reach back and pull her hips and she slides fully inside. “Now fuck me.”
She didn’t need an invitation and she is quickly pounding your bottom. You can’t help but moan little encouragements like ‘yes’ and ‘harder’. She was right, your boobs clap together. The clap of her hitting your bottom, her balls hitting your thighs and your breasts clapping fills the room. It feels like time stops, but looking at the clock as she cums it’s only been thirty minutes.
“Cumming deep inside like you like,” she leans over and whispers in your ear.
“I feel it. You are giving me a lot. It feels warm in my belly…”
When she finishes she pulls out and sits back. You turn over. You pull her clothes into a ball and put it under your butt.
“That was fun,” she says, eyeing you rubbing your belly. “Did I get you pregnant?”
“Don’t think so. We should try again?”
“We are out of time, I gotta get home. There’s always next week.”
“Okay, well good luck getting your clothes out from under my fat ass without another round. Your cock is still rock hard and those balls look fuller than ever!”
“Fuck, really? That’s why your legs are still spread? I’m used to the one saying when I’m done! Looks like we are going round three! Might take over an hour this time.”
“All the best ones do,” you smile back at her, her face smiling despite her reluctance.
She crawls over you and for the next ninety minutes, you let her play with your belly and breasts as she builds her orgasm. There’s no rush and your ass is hella loose by the time she speeds up and cums, hands squeezing your boobs. You learned her tempo, and have your hands squeezing her balls.
“Oh it hurts a little…ugh, but you got me by the balls, ugh…ugh…ugh…” You squeeze in the perfect rhythm to keep her cumning. “Ugh…ugh…ugh…” One hand moves to your belly. “Ugh…ugh…ugh…ugh…ughhhhhhhh!” She’s coming down but you squeeze every last drop out. “I’m out! Stoooop…”
“Yeah you are,” you finally agree. She rolls off you and onto her side. You retrieve her clothes and drape them let her.
“Thanks, Sam…”
You both take a few minutes to dress and you see you aren’t the only one walking funny. “You’ll be walking funny for a few days,” you mention.
“Worth it?” Janelle asks.
“Yeah! Good amount of cum, too!”
When you leave the room, you see s line of girls for the next class waiting. “All yours, ladies!”
“Looks like someone had a great time!” Someone mentions.
“Got quite the ass workout!”
