It was the middle of the day and business as usual. At their dinner table Mattew looked on Amazon for a good female chastity belt to contain Mandy's horny exteriors, bra + handcuffs too, for extra weight. This will be important soon. Once the perfect model was displayed he thought briefly about it and then bought it. Less than 3 seconds later, the payment was confirmed and the order was placed. He couldn't wait to see his girlfriend intimately restrained and choking on water as she was sexually frustrated. Minutes later, the item was dispatched. The next day... Mattew and Mandy were having dinner at the same time. The conversation eventually led to her being dunked by her persuasion. As Mattew said, "It's so arousing for some reason." Mandy put a paw in between her trousers. Mattew saw this and said, "Er, no sweetie, not anymore." Mandy was confused. He was saying it was arousing, right? Mattew said to her, "I've got a great new idea of how you and I can have fun together. Mandy looked at him and said, "Okay then, how do you or I go about this?" Mattew said "Usually you get to touch yourself, but I decided if you were forced to go without, you would be most frustrated and more willing to do kinky things. Chastity belts and bras also have weight which would help to hold you down." Mandy looked at Mattew excitedly and bit her lips. It sounded so hot being held down by metal by your lady parts. She said, "So when's it coming." Mattew pulled out his smartphone, unlocked it and went to look at his e-mails. The estimated delivery day was 2 days from today." He looked up and nervously said, "Err... 2... days. Is that alright?" Mandy nodded, she can wait that long, she thought. Until then, she could paw off unrestricted. After dinner, in the bathroom. Mandy decided now was the time to get off before that privilege was taken away. She lay in the bathtub and turned on the water. As the water flowed and become hotter, she took the shower and directed it towards her fluffy clit. She pulled the shower pipe which directed the water out of the shower head and towards her private parts. The blast of water tickled her clit and relaxed the muscles around it. "Ahaha... ohh", she moaned as the water was shot out of the shower head towards her. Water began to pool in the tub and her wet hair dropped downwards. After many minutes, the water was close to her chest. The water from the shower continued to massage her private parts. Then she had an idea. She would lie down with her knees pointed up and hold herself down as water continued to fill the tub. When the water was close to her maw she took one last breath in and held it deep. The pleasure from her clit increased and was very intense. Every muscle in her body was relaxed except for her heart which beat faster in an attempt to make up for the lack of fresh air she was denying herself. As the pleasure built up her clit began to throb and let out fresh pussy juice into the water around her. She tried to breathe in deeply while the orgasm happened but instead breathed in a mouth full of water. It filled her stomach and lungs. Instead of coughing it out, she breathed in more. Mandy realised she was alone and couldn't keep doing this. She let herself up out of the tub. It took almost 1/10 of a second because the tub was full of water pouring down the overflow drain. She raised her head up out of the water and swung forwards. She coughed harshly and a mouth full of water fell out of her maw. Then she breathed in deeply and coughed. She was so satisfied she decided she didn't want to orgasm again and thought it better to serve Mattew. Unfortunately, her heavy sexual barriers were still days away. They spend the rest of the day relaxing and spending time with each other as she recovered from the mouth fulls of water she inhaled. 2 days later... After dinner, there was a knock at the door. It was the Royal Mail and a man holding an oddly heavy medium-sized box. Mattew heard it and said, "Oh, that must be for me." and winked at Mandy. Mandy giggled and sat in anticipation. Mattew walked to the front door and took the box. As he did, he said "Thank you." and nodded in approval. The postie smiled and turned to the next house to them with a letter from the DVLA. Mattew walked with the box into the kitchen and plopped it on the table. She looked at it happily. He said, "Aren't you going to try it on?" Mandy said, "Okay." and used the knife she was using to cut her bacon to tear open the paper tape. Inside the foam filling was an Eevee-sized chastity belt, bra and handcuffs, all metal and weighed a noticeable amount. Mandy squealed with excitement and stood up to point out her private parts. Mattew picked up the chastity belt and slipped it up her left leg, and right leg, then tightened it. She said, "Ohh" as it locked down. Just like that, her pussy was completely out of touch. Next, the chastity bra. This time, Mandy picked it up and put it over her teets then in a sexy pose. Mattew then tied up back so it wouldn't fall down. Now, she couldn't even see or touch her teets. To him, she looked too different. Mattew suggested, "Why not put on a swimsuit? We'll be going 'swimming' later." Mandy nodded and went to walk upstairs. It's not that she couldn't move, but the weight on her lower and middle body means she had to put in more effort to walk at the same speed and it was so sudden it surprised her. She put on a swimsuit to hide it. It looked and felt sexy. It was a hot day and so their backyard pool was hot. Mattew and Mandy held hands as they walked towards it. Mandy sat on the steps and waited for Mattew to do something. Then she tried swimming. It was more difficult and required stronger arm and leg movements to stay afloat because of the metal that encased her private parts. The set of chastity restraints also included handcuffs which Mattew pulled out from a bag in the garden. Mandy saw them and blushed as she said, "Are those for me?" Mattew looked at her and said, "All you babe." On dry land, Mandy put her front paws out and Mattew put each paw through each cuff, then locked it, and then hooked it to her chastity belt. There was enough movement for her to unhook the cuffs chains but she chose not to because it felt so right. Lastly, Mattew took out a novelty anchor with a chain coming from the top of it. As soon as Mandy saw it she knew what she was in for; she would be handcuffed and anchored to the bottom of their swimming pool by her pussy. How exciting! As Mattew held it he said, "Why don't you go into the water and I'll let you try this thing." Mandy nodded and stepped towards the centre of the pool. The problem was she could only move within a few feet of the centre because it was too deep to keep her head above the surface. Mattew stepped into the pool's water and strode towards her. Once up close he said, "Ready babe?" Mandy started breathing in and out deeply. Mattew dropped himself under the water while holding his breath and clipped it to Mandy's chastity belt by a hole in the middle. He then picked her up by her arms and walked her towards the centre of the pool which was too deep for Mandy to handle. Mandy looked at him worried. Mattew said, "On the count of 3 I'm going to drop you in and you're going to try and escape. You won't be able just to swim away because you're anchored down by your pussy." Then, "3... 2... 1...", Mandy breathed in one last time and went splash. The small heavy anchor and chain pulled Mandy down. She was free to move her arms but that was it. Mattew worked his way to the pool steps with his head above the water but nipples and below under the water to hide his enjoyment. Underwater, the vulnerable Eevee tried carefully to unclip the hooks that limited her paw movements to just her crotch area. Would she free herself or continue to struggle and die as Mattew watches? Underwater, Mandy moved her left paw towards the clip that held her left arm towards the belt that contained her pussy. By beginners luck, the unclipped it. The then rushed her free left paw and locked right paw towards the hook that resticted her right paw. It was successful. She then struggled downards and grabbed the chain of the anchor that pulled her private parts into the depths the could not survive. She found the clip then released it and let it go. Immediately, she floated slightly upwards as the weight let go of her. The then put her paws upards and spread them out to swim to the surface of the pool and breath in. As her head penetrated the surface of the pool, she breathed in deeply and moaned as she let her spent air out. She looked around and saw Mattew sat on the steps. During Mandy's dangerous challenge Mattew was doing what she could not; masuturbating to their partner from the pool steps. As Mattew pawed himself off, Mandy poked her head above the surface. He watched her breath in and breath out, then approach him. She struggled towards him, panting and huffing. He says, "Hey, you made it! That's my boo." She tried to respond but was too busy paddling towards the steps. She kept doing, Eevee getting closed to the other. At the pool side she sits down. He looks at her and says, "Did you like that? You were under the water for almost a minute." She replies, "Yeah but it felt longer. I could barely move and I felt my vagina being dragged into the depths of the Earth." Mattew laughs at the comparison, "Haha, that bad huh? Let's get you out of there, you deserve it." Both get out of the pool stepps and get down on all-fours to shake. Not wet but still cold, they shiver as they slowly walk inside, up the stairs, and get themselves a towel. Mandy and Mattew are shivering at they dry their fur and absorb the heat in the air around them. As both sit on the bed rubbing their coats, Mandy says, "Are you gonna take this thing off?" Mattew says, "Sure, the key is in the kitchen." "Of course there's a key.", she thinks to herself. Bad ending: Mandy is unable to grip the hoops that restrained either paw. Instead, she tries desperately to unhook the clip the chain that held her body down, floating dangerously under the water. That too was unsucessful. As she struggles, she let of air in frustration. Almost a minute passes and she runs out of air. The pressure of the water filled the vaccuum of air in her lungs. The lack of fresh air and weight around her pussy and teets slightly arouses her, but now was not the time to think about herself sexually. The pool water forced its way from above into her lungs and stomach. She tried to cough it out but only breathes more in. Her windpipe closes, causing her to neither breath in or out any water. The lack of movement causes her lungs to burn. The complete lack of oxygen in her blood caused her to become dizzy and light-headed. The blurry, bright blue water around her slowly fades out. She has failed the challenged and has drowned held down in her own pool by her own lover. During this challenge Mattew was doing what she could not; masturbating to their partner from the pool. Her bubbles left the water of the pool which was surprisingly still. Mattew notices the lack of bubbles and knew she was in trouble. He jumps off the pool steps then dives into the centre of the pool where Mandy floated. Underwater, he swam towards her still body and unhooks the anchor that threatened her life. He then lifts her still body out of the water, propelling himself with his back legs. He lifted her above the surface and walked towards the edge. At the edge of the pool he lay her down and rescued her from unconsciousness. After 2 recovery breaths and half a minute of pounding above her metallic breasts she coughed and spat out some water, then breathed in deeply and out with an obvious strain. She looked around and said, "Where am I?" in a panicked voice. Mattew said, "Calm down, you're in safe paws." She sighed and said, "Oh, was I swimming again?" Mattew rolls Mandy over and says, "No, not really." She tried to move her front paws but only slightly. The shackles are still hooked onto her intimate belt. He says, "Let's get these off you and you can relax."
