Sammy wants to go to the gym to bulk up, however other plans come to mind.....


Things have been going smoothly for our horny group, with Adam finding a new job and also Grant and Sammy having a close relationship. However, Sammy has been feeling self-conscious about his body especially since his boyfriend is built like a tank. Sammy has always been a smaller person all his life. How will Sammy bulk up and get the body he desires? Let's find out!

“Why couldn't I have been one of the lucky ones?" sighed Sammy as he was looking at a video featuring muscular/big men. Grant walks into the room wearing his signature, ill-fitting lacy bra and panties and prepares breakfast for his favorite cat. “Hey Daddy! What would you like to eat this morning? Well besides my ass, hehe." Grant chuckled. The loyal dog notices Sammy feeling down and starts to worry about him. “Is everything okay, my love?" Grant asked.

Sammy snaps out of space after Grant asks his last question. “Huh? Oh yes sweetie I'm doing fine, nothing to worry about." Sammy replied. “Well alright, just remember that I'm always here you, daddy." consoled Grant. The burly dog kisses Sammy's cheek and decides to make the cat's favorite breakfast, bacon and waffles with milk on the side. Sammy smiles, but regrets not telling Grant what the real issue is.

After having a nice breakfast (and morning sex of course) Sammy drives over to Rigel's house and asks for advice about being more confident about his body. “Uh huh, I see" Rigel answered after hearing Sammy's insecurities. Sammy says “Yeah I've always been nobody's choice before I met Grant and I do appreciate him a lot, but I just wish I was satisfied with myself, especially my body." “Well you got a fat dick, that's something." Rigel laughed. “Besides that" Sammy grumbled.

“Relax, I'm just joking, my friend." Rigel stated. The small yet wise rabbit puts their hand on Sammy's shoulder. “Building self-confidence takes time and it's not healthy to compare ourselves to others, you can only be you." Rigel comforted. “You're right… But is there anything I can do to help build it faster?" Sammy asked. “Hmm… Why not try to exercise in the gym? You could even bring your boyfriend as well since he always works out too." Rigel replied.

“Hey… That's a good idea! I'll let him know right away!" Sammy beamed. The shy cat rushes out of the house and waves goodbye to Rigel, after a bit of a drive back home, Sammy explains the situation to Grant. “So… Do you mind taking me to your gym today? I really want to be bigger…." Sammy pleaded. “Hell yeah I'll bring you over! My other friends have been wanting to meet you!" Grant grinned while wrapping his burly arm around the cat. Sammy kisses Grant on the lips and thanks him for understanding, the couple grab their bags and head over to the local gym.

About 10 minutes later, they both arrive at the location, it is quite large and has nice air conditioning. Sammy decided to wear a white tank top with orange gym shorts, while Grant, being the exhibitionist he is, wears a similar outfit to Sammy except his tank top does not cover his rather large breasts/belly, being more akin to a loose crop top and his shorts do not fully cover his asscheeks, not to mention you can easily see him wearing a thong due to the shorts poorly covering his buttcrack. The two walk around for a bit while holding hands and they finally meet up with Grant's gym-bros. His friends are composed of a fat bear, a muscular lion and a musclegut dragon. The trio are a similar height to Grant being beyond 6 feet 4 inches.

The three large men give their greetings to Sammy and each one of them shakes his hand, much to Sammy's small stature not being able to handle the handshakes. “Ah, so this is the guy you're dating? You were right, he is quite cute" said the dragon. “Yeah Grant, when are you gonna let me have a piece of him? Heh." the lion chortled. “I bet you two break the bed quite often" joked the bear. Sammy blushes and is quite flattered at the compliments.

“Of course we do! He is my sexy daddy after all~" Grant gushed. “Not to be rude, but how come you wanted to join the gym? You don't seem like the type to be interested in this type of stuff" the dragon questioned. “Well. I want to be as big as you guys… Maybe not height wise of course, but I would love to be fit" Sammy confessed while twiddling his fingers. “Gotcha, gotcha. It's gonna take a lot of work to get nearly as huge as us, but don't get discouraged!" the dragon uttered. “He's right, my love. Though… I think we should do light exercises to get you started. Let's start on the treadmill first." Grant explained.

Sammy agrees with his large boyfriend and joins him on a (different) treadmill. The twink cat chose to walk at a brisk pace on his machine while the himbo dog decided to go at a faster pace, due to how fast Grant is jogging on the treadmill, his body (particularly his breasts and fat ass) starts to bounce and jiggle within each motion. Sammy tries his best to resist wandering his eyes towards Grant's jiggly body, but fails to do so. Grant notices Sammy eyeing him and grins. Despite Sammy pretending to not stare at Grant, he is ironically unaware that his large boyfriend sees him ogling the slutty dog.

Grant intentionally sways his hips and as a result, his cakes are jiggling like gelatin. Sammy stops the treadmill and can't help but to pop a boner. The gym crowd takes notice of the couple with a surprised but lustful reaction. The large big breasted dog stops the treadmill and can't resist his urges even in public. Sammy as well cannot stop these thoughts and slaps Grant's ass, with his backside having a very noticeable recoil.

“God, you're such a fucking slut. I love it." Sammy swooned. “Anything for my daddy~" Grant purred. The two make out in front of everyone at the gym and start doing immediate foreplay, with Grant stroking Sammy's fat cock in his shorts and Sammy groping Grant's soft yet large breasts. The audience in the gym stares in almost in a trance-like state since this type of “gym activity" never happens. With Grant and Sammy “tongue wrestling", Grant pulls out Sammy's dick out of his pants which can be seen as third leg, the crowd goes wild with some even stroking to the show including Grant's friends.

“Get on your knees, whore. Take off everything but your thong and put that mouth of yours to good use." Sammy demanded while sitting on a bench. “Absolutely, daddy," Grant replied. Grant strips in front of everyone and as he's taking off his tank top, his fat breasts bounce a bit and gets stuck for a moment under his boob. The massive dog proceeds to kneel in front of Sammy, because of how large his erection is, it casts a shadow on top of Grant's face with the dog licking his lips in anticipation. The himbo wrestler starts with slurping the cat's fat cock with rather large licks, Sammy moans in pleasure during the process.

Grant's back is perfectly arched while on his knees and because of his underwear leaving little to the imagination, it's possible to see his hole while he blows Sammy. The vast majority of the gym crowd masturbates to the view, with even some of the crowd mimicking Sammy and getting blown by their own partner. In less than 5 minutes, the gym turns into a massive orgy. As Sammy cannot think straight while getting his dick sucked, Grant starts to suck more intensely with very loud slurps. Sammy screams in pure bliss and starts leaking pre-cum which the dominant twink cat gestures to his big boyfriend to use his chest.

“That's right you cum slut, stroke my cock with your tits." Sammy directed. “With pleasure, daddy~" cooed Grant. The milky dog placed his breasts between Sammy's thick meat, they both can't resist to moan within each thrust. After a minute or so of Grant putting his tits to work, the small yet dominating cat pinches Grant's nipples much to the dog's surprise and starts thrusting to fuck the breasts himself. “Mmmph… Mmmgph!" Grant said as he's deepthroating Sammy while still getting titfucked.

“F-fuck I can't hold it anymore…" Sammy mumbled. The gym crowd starts chanting after hearing the horny cat about to blow his seed. “Cum… Cum.. Cum… Cum! Cum! CUM! CUM!" The chanting grows louder and louder, with even Grant's friends cheering amongst the orgy. Sammy's face turns completely red and starts to stroke furiously.

“Please daddy… I want to eat your cum… I'll swallow every drop… Cum for me…" Grant begged. The stroking becomes more and more aggressive with Sammy even using both hands. Between the crowd chanting and Grant opening his mouth while moving his tongue, Sammy growls and unleashes his nut all over Grant's face and chest. Loads upon loads of seed are spewing from the cat's dick and are creating puddles of cum. “Shit…! I… I can't stop cumming..!"

Everyone's eyes start to widen seeing the bench, Grant and the floor getting covered in seed, and likewise, several members of the gym start to cum as well, creating a big mess in the building. Sammy finally stops and passes out from pleasure on the bench he was sitting on. About two hours pass after the “workout" and Sammy finds himself waking up in Grant's car. Sammy takes off the blanket he was covered in and finally starts to get up.

“...Wow, I just had the weirdest dream, honey. We had sex at the gym and everyone had an orgy during it. Your friends joined in as well." Grant chuckles “Daddy, that was no dream haha, you fell asleep after you nutted. The gym owner wasn't happy about it though so we had to clean up everything and I've been waiting for you to wake up." Sammy covers his mouth and turns redder than a tomato “HUH?" Grant strokes Sammy's head while saying “I know right? Quite wild, but aside from the owner, everyone including me REALLY enjoyed it!" Sammy sighs, however Grant hugs the kitty to reassure him.

“Sammy… You don't need to change who you are. You're already attractive and I love you for you. Don't forget that, my love" Grant professed. “Grant… Thank you…" Sammy said. The two embrace for a moment, though Grant breaks the silence. “So uh… My pals would love to hang out with you again and it doesn't have to be at the gym as well, maybe we all could plan something" Grant addressed. “Absolutely, dear! But for now, we should really be heading home and making dinner."

Grant jiggles his belly and agrees, the large dog drives back to the apartment and helps Sammy decide what to cook while wearing only a small pink apron. The two later head to the bedroom while cuddling in their sleep.

How adorable. Until next time! Thank you for reading.
