For said characters, picture Happy Valley Park NPC's in China (ripped, gorgeous men, often dressed in traditional Historical attire) as well as super heavyweight wrestlers such as Ryota HamaHuman UnderwearTwo characters: Ryuue- pretty face, ripped hunk, About 5ft2in, meaty perky tits, thanks to plenty of chest days. Also plenty of glute/squat days, so you can imagine a nice round and full ass. He is handsome, amber eyes, dark black-burgandy hair. Face framing bangs and long hair (down to his waist).Niku- boyfriend, roughly 6ft5in and 450lbs. For this story, I'll need to go into detail about Niku's dimensions. He himself is also muscular with a soft layer of fat on top. Given that, he has pretty perky tits Which are also full and fat. His stomach is as wide as his ass. Given his weight, you might picture someone like Yokozuma (rest in peace). Niku has a handsome face as well, nicely rounded out with fat on top of his facial features. Green eyes, dyed blue hair (modern man bun).The height differences are important for this scenario.So, human underwear- basically Ryuue lies underneath Niku With his face in his crotch. His waist and abs are under his hips. This is the focal point of where Niku's weight rests.
Ryuue's body is slung underneath Niku, like a thong, with his face in Niku's crotch/ass cheeks and his waist/abs snug between thighs.The height differences and body types play a major Role here. Given how tall and wide Niku's body is, and how Ryuue is significantly shorter and slimmer, especially around the waist, Ryuue's body fits snugly between Niku's thighs. Then, what keeps him “worn like a thong” for Niku is bondage. For this scenario, they're using leather cuffs and chains. Regardless of which way Ryuue faces, his arms and legs are hog tied around Niku's waist/stomach/ass. This works because of his shorter height. His arms reach just enough to connect to his legs. His legs are open, and his knees wrap around Niku's side. His arms wrap around the other side so that his wrists are tied to his knees and his limbs form what would be the waist band of a thong. For good measure, the chain connecting his knees and wrists are also attached to suspenders. The suspenders ensure that Ryuue does not slip out of Niku's thighs/crotch/ass.While Ryuue is not so heavy, still the suspenders eventually dig uncomfortably on Niku's shoulders. So Niku, while wearing his Ryuue-thong, will take Sitting breaks. Yes, full weight sitting breaks.So, while walking Ryuue's waist is snug between the tight passage between Niku's thighs. Given how fat Niku is, his thighs squeeze Ryuue tightly without any exerted effort from him. At this level of squeeze, Ryuue can manage labored but consistent breathing. While walking, as his thighs slide back and forth, the fat and muscle have to squeeze Ryuue tighter. At this level, Ryuue's waist can barely Expand to breathe. There are brief moments of very minimal give between thighs and Ryuue desperately gasps for air during the steps Niku takes.This is all assuming Ryuue's head/face are free to move or hang. So, when going out, Niku necessarily needs to be fully dressed to both be decent and to hide Ryuue. Thus, Ryuue's face is snug smothered by Niku's fupa or inside his ass cheeks.All of this sounds like it might suffocate Ryuue into passing out but Ryuue also commits to ab days at the gym. Even though Ryuue's waist is tightly squeezed in Niku's thighs, Niku's fat is soft enough to give the slightest way so that he can utilize the strength of his abs to maintain breathing room. By contracting and flexing his abs, he creates a wall protecting his lungs and diaphragm enough for ,granted labored, consistent breathing.Knowing all this, Ryuue and Niku have practiced and prepared this bondage enough To feel confident in wearing Ryuue like a thong while Niku travels about.Ryuue- is your typical masochist who mostly enjoys his treatment in the form of breath play, full weight sitting, body slams, and crushing.Substory- Chasing SuperchubsHe found Niku at an event for masochists and sadists to meet up. This event was particularly advertised as welcoming chubs, superchubs, and chasers. Actually, the way they met really sparked their dynamic. The event required traveling via elevator from the first floor to floor 20. This was a very popular event so a tight squeeze was standard throughout the day. Ryuue got on at the first floor and the elevator wasn't fully packed.Reaching the 2nd floor, enough people entered to fill the space like a can of sardines. Ryuue is a very accommodating person and immediately moves back to give space for the new crowd. He briefly caught sight of Niku, being one of the first to enter through the door, and noticed how attractive he was. Then of course, shying away and averting his gaze to not be rude.Niku wasn't necessarily paying attention, walking in while looking at his phone. He Didn't want to make it hard for the remaining crowd to enter, so he also walks to the back of the elevator. As the crowd fills in, he's forced to back into Ryuue. Niku is startled feeling something behind him but wasn't sure what it was.The elevator doors closed. The space is packed tight. At Ryuue's height, Niku's full and expansive ass fits perfectly to compress his abdomen. Even if Niku wanted to, he couldn't move to give Ryuue relief. While riding the floors up to 20, Niku feels hot air hitting his back. He turns around as best he can and feels the thing behind him slide against the wall. Ryuue is trying his best not to be rude so he tries not to make a fuss. While sliding, Niku's girth does force a groan from Ryuue. Niku is even more confused and turns the other way and feels the thing slide with him again. He hears a new sound like a gasp. He figures he will need to wait till they reach their floor.Floor 10Trying to ignore it, he continues to feel the hot air brushing against his back in short and fast intervals. The thing starts moving! Niku is startled and instinctively backs up to turn around fully. This time he hears a coughing groan and feels warm sticks pushing against his ass cheeks and stomach.At this point Ryuue cannot afford to keep his silent composure. His vision is blurring as his waist is pushed So hard that he can almost feel his belly button touch his spine. He desperately Tries to push the girth away with very very little progress. His ears are pounding with his heartbeat in and out of his survival instinct he starts slapping the fat person crushing him into the wall.People are turning to look at the commotion and Niku feels a hot wave of embarrassment.Floor 12- door opens and some of the crowd leaves.Niku can finally move and find out what the thing is behind him. He sees Ryuue, pale in the face, near cyonatic, drop to the floor.
The doors close. It looks like the entire crowd left.Floors 13-15 Niku helps Ryuue stand up, but he keeps dropping. Ryuue is so out of breath he cannot make words. Niku keeps an eye on him and helps Ryuue stand and rest against the wall. Niku holds Ryuue up with his left arm hugging the body around the back and his hand at the other side. Niku waits concerned and by floor 15, Ryuue starts to regain composure.Ryuue is so embarrassed and profusely apologizes for touching Niku. “I'm so sorry sir. I really didn't mean to be rude. I hope you can understand-”
Niku interrupts and Says, “my guy, I was crushing the air out of you. You're good. I'm sorry.”Ryuue's face now flushes with blushing red and averts his gaze. “It's totally fine. I'm okay”Niku, “you sure? I had no idea, im so sorry. I didn't even consider a person was behind me. it was pretty tight for you huh?” Looking genuinely concerned.The thought genuinely causes a spark of arousal throughout Ryuue's body. “Um, well practically yes. But….don't apologize. I'm somewhat used to the experience.”Niku's interest is piqued and the gears in his head are turning. “Used to…being crushed?”Ryuue's face is now beet red and he's looking at the wall to his right avoiding any eye contact. Niku, “i see…you're going to the event too?”Ryuue, “is it that obvious?”Niku, “hey, let's take a look around together. Yeah?” (He subtly diffuses Ryuue's embarrassment by shifting the direction of the conversation.)Ryuue, “id like that :)”Niku offers a fist bump and Ryuue returns the gesture. This marks the first gesture of mutual affection. Throughout the event, they discuss the things they see. They discuss common interests. Slowly this becomes discussion about their personal passions and goals. Both men are truly enamored With each other.By the end of the event, they're holding hands.
