The rules of the bell game were simple.
Whoever could make their bells ring the loudest won. But simple rules didn't mean there was no strategy involved.
Since they couldn't use their hands, they had to rely on shaking their bodies to make the bells ring.
There were two ways to increase the volume of the bells.
The number of bells and the intensity of the shaking!
With the same level of movement, more bells meant a louder sound. With the same number of bells, a more intense movement meant a louder sound.
More bells also meant more weight!
A more intense movement meant greater momentum for the bells!
But more bells and more intense movements would also bring greater stimulation to their bodies, and their physical endurance had limits.
These bells weren't just held in their hands; they had to be hung on their sensitive spots!
It was manageable when they were still, but once they started swinging, the stimulation wouldn't just increase by a little bit. They had to find a balance between the two!
Besides the attachment points on their tokens of affection, they could also use clips to create more attachment points, thereby increasing the number of bells.
Two on the chest, one at the crotch, plus the rear. The clips and plugs Rin Ito had brought were exactly for giving them more attachment points!
The only place that could hold a lot of bells was the rear, but the range of motion for the rear would be restricted by the dildo—which was the same size as Rin Ito's—and it would also consume more stamina.
It all depended on their personal choices.
"P-pervert..."
After Rin Ito explained the rules, Itsuki looked at the pile of bells with flushed cheeks and muttered softly. Staring at the clips and bells, she felt quite troubled.
It didn't hurt when she put on her token of affection, but these clips had teeth on them; they looked like they would hurt a lot... When they played card games in the past, they had used clips as punishment tools. Clipping them on ears and lips hurt so much; wouldn't clipping them on such sensitive spots hurt even more?
And they had to swing the bells too... Maybe I should just forfeit and hang a single bell on my chest.
While Itsuki was still hesitating, Yotsuba had already taken action.
Without hesitation, she picked up two clips. She attached one to the side of her chest that didn't have a token, and the other to the 'little chestnut' between her legs, which was already fully aroused.
Although Yotsuba was also a bit afraid of the pain... I absolutely have to be first!
In reality, after clipping them on, Yotsuba felt it wasn't too bad. The tingling, numbing sensation wasn't as painful as she had imagined. After attaching scattered bells to each point, Yotsuba shook her body.
Instantly, the jingling sound of bells echoed in the room.
"Doesn't it hurt?" Itsuki reached out and gently pulled the bell at Yotsuba's crotch... It's being squeezed flat and stretched out; does it really not hurt?
"It's okay... once you get used to it, it actually feels kind of good." Yotsuba looked at the plug and considered it for a moment. Although the rear point could hold a lot of bells, having both front and back filled would restrict her movement.
I'll pass on the rear attachment point! But I can add a few more to my chest without affecting my movement!
Yotsuba decided on her strategy: most of the bells on her chest, a few at her crotch, and absolutely none on her rear, which would hinder her movement. She wouldn't even use the plug!
Itsuki simply gave up; she had no strong desire to win and just symbolically hung one bell on each spot.
Nino and Miku didn't care much about the overall order, but they both had a slight obsession with winning... At the very least, I must beat Miku (Nino)!
After cutting a hole in the crotch of their pantyhose, the two attached the clips.
Miku knew she lacked stamina. To beat Nino, she could only rely on numbers, so she hung as many bells as she could bear.
Itsuki felt like Miku's breasts were being dragged down slightly by the weight of the bells.
Nino adopted a balanced strategy, hanging a few bells on each attachment point.
To Rin Ito's slight disappointment, none of the four chose the rear attachment point.
"Since you're all ready, let's prepare to start."
"Ready? Let me see, let me see, let me see." Ichika's voice came from the phone. Rin Ito picked up the gimbal and aimed it at the four girls lined up in the room, each with a suction-cup dildo at their feet.
"No using your hands. You decide your own poses."
Actually, there were roughly two poses: one was a deep squat-like pose, and the other was getting on all fours, raising the rear in a duck-sit-like posture, and sitting down hard.
However, they all chose the first pose. Although the second pose consumed less stamina, this competition wasn't about the number of repetitions, but the volume of the bells.
The second pose wouldn't provide enough movement for the chest, so the bells wouldn't ring loud enough!
"Uwah... Miku, why did you hang so many bells? Doesn't it hurt?" On the screen, Ichika pinched the crystal on her own chest and pulled it down. The tingling pain made her body go slightly soft, but after getting used to it, it actually felt quite nice.
But the crotch attachment point... If she wasn't wearing a chastity belt, Ichika would have wanted to try pinching it tightly and lifting it up to see how it felt. It was the most sensitive spot on the outside of the body; pinching it hard would definitely hurt.
"You guys sit down first."
The bodies of the four girls had already been primed when Rin Ito had them underfoot earlier. The girls carefully spread their legs and aimed.
From his vantage point, Rin Ito could see the differences between the four. As their thigh muscles engaged, he could clearly see the taut muscle lines on Yotsuba's legs. As for Miku, the sports idiot... the edges of her cut pantyhose pressed slightly into her flesh, her legs soft and slightly plump as always.
"Miku needs to exercise," Ichika muttered absentmindedly from the other end of the screen, looking at Miku's thighs. They were delightfully plump now, but if she didn't manage her figure and kept eating, she would definitely get fat.
Exercise or diet—if you don't want to get fat, you have to do at least one.
Although Itsuki was the biggest glutton, she also paid great attention to exercise, especially her abs! Although the muscle definition wasn't prominent, it was clear that they were quite firm with no excess fat.
Nino regularly practiced yoga and managed her diet; her figure was the most balanced among the four.
"Uu..." Miku let out a soft whine. She had no time to listen to Ichika talk about figure management now. She had hung so many bells that even the slightest movement caused a pulling sensation that made her legs weak.
Trying desperately to maintain her pose and aim, Miku's thighs trembled like fluttering wings.
Yotsuba and Itsuki aimed first. After taking a deep breath, the two slowly squatted down... No! Itsuki slowly squatted down; Yotsuba, after aiming, dropped down without hesitation.
Having spent all her time studying lately, even her energy for masturbation had been drained. As the transparent toy stretched her open after a long absence, drops of clear liquid were squeezed out from the gap, and Yotsuba narrowed her eyes in pleasure.
"Uwaaah...~"
Following Yotsuba were Itsuki and Nino. Miku, unsurprisingly, was the last to slowly squat down, a layer of cold sweat beading on her forehead.
"Ready? Then I'll start the countdown. 3... 2... 1... Go!"
Yotsuba held her breath and focused on the countdown. The feeling of being pushed to her absolute deepest core made her legs slightly weak, but the moment the countdown ended, she raised her hands behind her head and took a deep breath.
"Jingle jingle jingle~~~"
As the bells rang, let alone Rin Ito, even Nino and the others were dumbfounded.
Afterimages!
They saw afterimages!
Yotsuba squeezed her eyes shut, steeled her heart, and performed half-squats at top speed, squatting back down the instant her body almost left the transparent shaft, then rising again at maximum velocity.
"Uuu...!!!!"
With no restraint, her massive breasts flew up and down with her movements, creating a faint afterimage in Rin Ito's eyes!
The supposed competition had turned into Yotsuba's solo performance!
The jingling of the bells merged with the squelching plop-plop of wet sounds. The floor beneath Yotsuba became soaked at a visible rate. Not just Rin Ito, but Nino and the others were also mesmerized.
Seeing this scene was worth dying for!
Yotsuba's speed increased, her alluring moans harmonizing with the bells and wet sounds into a symphony.
"Eeeek!!!!"
With a high-pitched cry, the suction-cup toy was actually lifted off the ground by Yotsuba!
Nearing the edge, Yotsuba couldn't care less about anything else. For the final thrust, she used all her strength, tensed her body, and squatted down deeply. The clips on her chest and crotch were flung right off, and the sudden, intense stimulation sent her straight over the edge!
"Hiss..."
Rin Ito sucked in a breath of cold air, hastily tossed the phone aside, and caught the exhausted Yotsuba. The crimson peaks on her pale, soft breasts and the delicate bud at her crotch were swollen dark red from the overly violent swinging. Only the side wearing the silver ring, protected perfectly by the system, remained tenderly pink.
"Hah... did... did I win?"
Gasping for air in Rin Ito's arms, Yotsuba's flushed face was hazy, her delicate eyebrows furrowing slightly as if only just now feeling the pain.
"You won, you won... holy shit."
Before Rin Ito could finish, Yotsuba, drawing strength from somewhere, grabbed his shoulders, pushed him down, and straddled him.
With her hands planted on his chest, her soaking wet crotch, and her drooling mouth parting eagerly, she couldn't wait any longer.
Slurp~
Her tongue swept over her cherry-pink upper lip, licking it clean. Her blue eyes locked onto Rin Ito's like a predator staring at its prey, both her upper and lower mouths frantically secreting fluids from sheer craving.
"Wait a minute!!!!" Ichika's voice rang out from the phone. On the other end of the screen, Ichika wanted to cry but had no tears... When Rin Ito went to catch Yotsuba, he had casually tossed the phone aside. Now, she could only hear the sounds but couldn't see the video.
Right now, Yotsuba only had eyes for Rin Ito.
The bell hanging from her token of affection jingled faintly with her every breath. As the ringing grew louder, Yotsuba's breathing quickened.
Swallowing her last mouthful of saliva, Yotsuba slowly lowered her hips and captured Rin Ito's lips in a kiss.
"Since I won, I'll be digging in~"
"If you're going to start, at least aim the camera first!"
No one paid attention to Ichika's voice. On the other end of the screen, the helpless 'wife' could only listen to her sister's alluring moans and the jingling bells.
