“Back, get back you foul beast.” Billy cried out as he stood in front of the playhouse and brandished his foam sword and shield keeping his brother Michael at bay. “I will not let you get the princess’s” Michael picked up a pile of leaves and threw them at his brother while giving a hissing roar to simulate a fire breath attack. “Foolish dog, those princess’s will be mine and there is nothing you can do to stop me.” Michael said in his best attempt at a deep voice. Inside the playhouse Kerry and Sally were sitting back giggling and giving over the top reactions to what was happening outside. The fight for the princess’s raged on, Michael got in a few attacks with his claws as well as his mock fire breath attacks. Billy was able to get in a couple of slashes with his sword. “For the kingdom” Billy shouted as he thrust his sword forward. Michael caught the foam sword under his left armpit and fell back into a pile of leaves. He overacted his death scene by twitching and giving several death rattles before finally going limp with his tongue sticking out. Once the mighty dragon was defeated the girls came out of the playhouse to meet their knight in shining armor. “Brave night, you have defeated the dragon. How can we ever repay you?” Kerry asked as she let her hand slip down to discreetly grope Billy’s padded crotch. Billy winced a little as he was not expecting the grope, also nervous that Sally was going to see, and didn’t want to get in trouble for doing things like that in front of her after their parents told them not to. He moved Kerry’s hand away and puffed out his chest a little. “It’s just what brave knights do princess Kerry.” “You’re the bravest big brother ever.” Sally said as she hugged Billy tight. Michael, after hearing what Sally said, picked his head up and looked over in their direction. “And what am I?” “You’re the scariest big brother ever.” Sally said as she jumped into the pile of leaves with Michael. “But scary to everyone else,” She said, as she got up and straddled Michael’s stomach and sat down on him. “You’re gonna scare all the bad people away like this,” Sally lifted her arms up, arched her fingers like claws and gave a cute little roar causing Michael to bust out laughing at how cute his sister was being. The group of children continued to laugh and play in the pile of leaves until Sally saw the back door of the house open and Jay walk into the backyard. “Hey everyone look, Jay’s awake.” Sally called out as got up and ran over to him. “Jay, Jay come on, you have to meet our friend Kerry.” She said as she ran up to him and took his hand tugging him along. As much as he wanted to fight it, to be left alone, he let Sally drag him to the others. “This is my best friend Kerry.” Jay was brought to a female snow leopard in a white shirt and powder blue skirt. “Hello I’m Kerry.” She said, offering her hand out to him. Jay was a little hesitant at first but figured it was going to be less awkward if he didn’t say a proper hello. “Hi I’m Jay.” He said, shaking her hand. Kerry, while still holding onto Jay’s hand, rushed off in the opposite direction and pulled him along with her. “Mike’s counting for hide and seek.” Kerry called out as she ran off with Jay. Both Billy and Sally ran off as Mike buried his head in the leaves and closed his eyes and started counting backwards from 20. Jay was a little surprised by the sudden running off, he was also finding it a little difficult to run in the diaper he was wearing, but he did like hide and seek. It was always something he was good at. Kerry rushed the two of them off to some bushes along the back fence of the yard and crouched down. The spot was barely big enough for the two of them, they had to squat down facing each other to fit in and not be seen. Kerry put her finger up to her snout muzzle and gave the ‘ssh’ signal. Jay nodded and kept quiet. He noticed that Kerry’s skirt was hiked up revealing her diaper to him causing Jay to blush and turn his head away. Kerry wasn’t looking at Jay, her eyes were fixed on Michael, watching him as he got up from the leaf pile and started looking for the others. It wasn’t long before Michael was able to find Sally as she wasn’t the best at hiding. “Should we move?” Did Sally see where we were hiding?” Jay asked. Kerry shook her head. “She doesn’t know about this spot, but Billy does. If he’s the seeker we do need to move.” Kerry whispered back. Jay nodded and stayed crouched in the bush with Kerry. Sally’s search for her siblings and friend had been going for almost ten minutes. “Wow, Mike and Billy are really good at this game.” Jay said as he looked out to the yard. “Do you know where they’re hidden?” “I think Billy’s under the log pile over there.” She said as she pointed to a pile of logs on the other side of the back yard. “I think the hole he dug is still there. As for Mike, I’m not sure. If this keeps up though one of them will let Sally find them so she doesn’t feel bad.” Jay gave a little bit of a smile hearing what Kerry said. As the pair hid in their bush Jay began to hear a sound, it sounded like a trickle but turned into a hissing sound. He looked around and eventually his eyes landed on Kerry’s diaper. As the hissing sound continued he watched the front of her diaper begin to swell up and the prints on the diaper begin to fade. Jay could immediately feel his cock coming out of his sheath. The awkward position he was in and the padding between his legs caused his erection to strain against his padding in a very uncomfortable way. Jay whined a little at how uncomfortable his erection was. Kerry heard him doing this but before she could ask what was wrong Jay stood up from where he was standing and popped open the snaps at his crotch and reached into his diaper to adjust himself. With all of the commotion Sally’s attention was brought to the bush where Jay was now standing and ran over to him “I found you Jay, you’re it now.” Sally called out. Not wanting to give Kerry’s position away, Jay just sighed “Yeah looks like I’m the seeker now.” he said, in a mock defeated tone. “Guess I better get over to the tree and count.” He said walking out from behind the bush. Sally pointed to the unbuttoned shortalls. “Why are your shorts not snapped? Kerry asked, pointing them out. Jay remembered what his foster parents said about no sex talk with sally till tomorrow. “Um, well the diaper is too thick and when I squatted down the buttons came undone.” he said trying to close the snaps on the shorts. “But wait, why did you stand up?” “Ummm,” nothing was coming to Jays’s head, “a bee landed on my nose?” he said in a slow thinking tone. Sally giggled “Silly Jay bees aren’t scary.” Jay gave a chuckle under his breath. “Yeah I guess you’re right.” He said struggling with the snaps under his crotch. “Here Jay let me help.” Sally said as she reached under and snapped the last few snaps closed on his shorts. The feeling of Sally's hands brushing up against Jay's diaper caused his erection to strain even more. “Thank you Sally,” Jay said with a slight grunt. Okay go and hide and I’ll seek.” he said making his way over to the tree. As he started counting, Sally took off running to her hiding spot. Just as Jay finished his counting and announced ‘ready or not here I come’ the back door opened up and Martha stuck her head up and called to the kids that lunch was ready. In an instant the kids ran from their hiding spots, Billy was exactly where Kerry said he would be and Jay jumped down from the tree he was hiding in. Kerry was the last to run out, not wanting to give her good hiding spot away. Jay was the last one in, the padding of his diaper was rubbing against his erection making it super awkward to walk. After lunch Martha gathered the kids into the living room for nap time, even the older boys. Sally, and Billy laid on the floor with Mike. They propped themselves up with pillows and cushions so they could watch the naptime movie, while Jay and Kerry sat on the couch. Half way through the movie Billy and Sally were fast asleep. “Hey, Jay, why did you stand up during the game? And why did you put your hand in your diaper?” Kerry asked. Mike heard this and turned around. “Yeah why did you do that?” He asked. Jay’s ears fell flat against his head as his face turned bright red and he turned his head away from Kerry and Mike. “I… I was just…” Jay responded in a quiet voice. “What were you fixing your boner?” Mike asked with a slight chuckle. Jay got off the couch and waddled his way back to the kitchen table where he took a seat and sat in silence. Martha was in the kitchen cleaning up from lunch and watched as Jay walked up to the table and sat down. “Hey buddy, what’s wrong are you still hungry?” She asked, putting some plates away. Jay shook his head and stayed quiet. Martha looked over to Jay and could see the mixed emotions he was having on his face. She stopped what she was doing and walked over to the table and sat next to Jay. “You know Jay, the longer you bottle things up, the harder it’s going to be opening up, tell me what’s wrong dear, you can tell me anything. Jay, already having been on the verge of tears again sniffled and wiped his nose. “Anything?” he asked without looking up. Martha put her hand on his shoulder. “Come one, let’s go talk in my room.” The pair made their way to the master bedroom. “Remember, you can tell me anything.” She said pulling a chair to the side of the bed for her to sit down on. “Have a seat and tell me what’s wrong.” She said patting the edge of the bed in front of her. Jay sat down, but did not look at Martha. “I never told anyone this, not even the therapist lady. When the older boys couldn’t have sex with the toddlers they used me, and even made me wear diapers while they did things to me. They even made me use them.” Jay said, still not lifting his head up to look at Martha. “We know that Jay, it’s all in the file they sent us.” Martha said in a soft voice. “I know, but the part I never told anyone is that after a while, I like the feeling of being in a diaper and using it. Sometimes I would put one on even if the older boys didn’t make me.” He said this time looking up to meet Martha’s eyes. “Now when I see others wearing diapers or I’m wearing diapers I get erections and horny, and I want to do the things the older kids did with me.” Jay stopped as he had already told Martha that part. “That last part was in the file dear. It was a psychological analysis, that’s why the therapist wanted to put you here, so those things feel normal for you.” She said, putting her hand on his knee. “What you have is a diaper fetish, that means you find it sexy when someone or yourself is in a diaper. Tony and I grew up here in dragon's heart. We wore diapers till we were 21. Sometimes when we are sexual with the kids we’ll put on diapers as well.” Jay’s mind immediately went to the thought of his foster parents in diapers making love to their kids instantly causing another erection. Martha recognized the little goofy expression on Jay’s face as him being turned on. “I think we’re going to change our plans about introducing sally to sex from tomorrow to tonight so that way the whole family can have some fun,” she said, while putting her hand on Jay’s chest and gently laying him back onto the bed. “Put right now it looks like you need some release.” She said, letting her hand trail down to his padded crotch. She popped open the snaps at his crotch and gave a good firm squeeze of his diaper, feeling the little erection it contained. “You can say no or stop at any time. Do you want me to stop.” Jay hesitated but finally nodded his head slowly. Martha took her hand away from his diaper “I’m sorry sweetie, I thought that’s what you wanted.” “It’s not that, it’s just.” He paused, not knowing if he should say what he wanted. “I just. I like it when it’s someone my age or an older male.” His face turned bright red when he finally confessed. His erection is clearly making a tent in his diaper now. Martha gave a slight chuckle. “Well, I think Kerry would not mind helping you with a release, She did have her eyes on you the whole time you kids were eating lunch.” She said standing up. “Let me go and see if she wants to have some special play time with you, is it okay if Mike comes along too?” Jay thought about it for a minute and nodded his head yes. He figured he might as well get used to having ‘special playtime’ with Mike since the two would be living together and sleeping in the same room. Martha left the room and came back with Kerry and Mike a minute later. “They both agreed to help you out Jay. Now remember, when someone says stop or no, you have to respect that okay? The three nod in agreement. “Alright I’ll be sitting right here, so you three can explore each other safely” Mike started with getting himself down to just his diaper and getting into the middle of the bed. Kerry followed suit, she pulled down her skirt and pulled off her shirt and got into the bed with Mike. Both had very wet diapers on. Jay stood up and stripped down to his diaper as well and joined Mike and Kerry on the bed. “So who do you want to play with first?” Mike asked. Both Mike and Kerry looked insanely sexy sitting there in nothing but wet diapers. His eyes fell on Kerry though. “K...Kerry, can I play with you?” Kerry blushed and nodded to the proposal. Jay scooted over to Kerry’s spot on the bed and sat in front of her not knowing where to start. Kerry could see the hesitation in Mike’s face as he sat there in front of her not knowing what to do. “I can rub your diaper, or you can rub mine.” she suggested, I can suck on your peen, or you can lick my kittie.” She giggled before saying the next part. “Or you can hump me, my big brother and daddy do all the time, I don’t mind.” Jay’s ears perked when he heard the last part and nodded his head. Before he could start removing his diaper Martha stood up and walked over to her closet. “Before you all do that let me put down some pads just in case.” Martha pulled some absorbent pads out of the closet and placed them on the bed for the kids to be on. Jay and Kerry moved onto the pads and Jay removed his diaper, letting his erection spring free. Kerry laid back, her legs spread open waiting for Jay to pull the front of her diaper open. He fumbled a little, but it was mostly due to his anxiousness. When he pulled the front of her diaper down and revealed her vagina he was in awe, almost like he was seeing a vagina for the first time. Jay picked her legs up, like he had seen done back in the group home and moved closer. He lined up his cock with her entrance and pressed the tip against her lips. Before thrusting forward he looked Kerry in the eye, she looked into his eyes as well and nodded. Jay thrust his hips forward getting his cock down to the base of his knot. Kerry gave a soft moan as she felt the base of the knot press against her. Jay gave a shaky deep inhale as he penetrated Kerry. His body lightly trembled as this was the first time he had been the one penetrating. He let his emotions calm a little before pulling his hips back and thrusting forward again. When his cock slid in again Jay let out a passionate moan as he had not had this feeling in a long time. He began to thrust in and out of Kerry at a slow pace. His pace was slow but it at least had some rhythm to it. Kerry was even able to match each thrust with one of her own, which drove Jay to moan even louder. Sitting off on the side Mike had his hand down his diaper stroking his own cock as he watched his new foster brother bang his friend. Sitting next to him on a chair, his mother had her hand down her pants as well while watching the display in front of her. The room was filled with a mixture of moans from Jay and Kerry as well as the crinkling from Mike’s diaper as he stroked himself and Martha’s soft moans as she teased her own clit. Both Jay and Kerry were lost in the passion of their love making, his little sack tapping her ass as his knot bumped into her lips. As he continued Jay could feel the oncoming approach of his orgasm, his pace quickened as he could feel his little balls tightening up. With one last thrust he was able to push his knot past Kerry’s lips and get his knot into her vagina. This sent Kerry over the edge of her orgasm causing the walls of her vagina to clamp down on his knot. Jay let out a cry of passion as he threw his head back. His cock, twitched and his balls pulled in shooting three little ropes of cum into Kerry’s vag as she rode out her orgasm. Taking deep breaths Jay was coming down from his orgasm. He gently pulled his cock back out of Kerry, his knot wasn’t that big yet, it took a few tugs but it was able to come out painlessly. Feeling a little exhausted Jay moved to lay next to Kerry. She rolled onto her side and smiled at Jay. “Thank you for letting me do that.” Jay said. “Anything for my new friend.” Kerry said. “I think Mike could use some help over there” She said pointing over to Mike who still had his hand down the front of his diaper. Jay rolled over and crawled over to his brother and opened the front of Mike’s diaper. Mike let go of his cock and laid back expecting Jay to continue stroking him. He wasn’t expecting Jay to take his length into his mouth. Jay took Mike's cock down to the base. He let his tongue rest on the underside of Mike’s cock as he slowly bobbed his head up and down. “Oh little brother don’t stop” Mike moaned as his toes curled. Mike was already close to the edge of his orgasm but having an unexpected blow job from his new little brother put Mike fast over the edge. “I’m going to squirt,” Mike said as he thrust his hips up. Mike kept his mouth around Mike’s cock as he shot four ropes into Jay’s mouth. Jay swallowed the cum and cleaned his brother's cock off before laying down next to him on the bed. “You didn’t have to do that, you know that right?'' Mike said, rolling onto his side, his cock becoming flaccid and retreating back into his slit. “Jay shrugged. “I thought, since we’re going to be living together, it was eventually going to happen.” Mike leaned in and kissed Jay on the cheek as their mother got onto the bed and started putting the kids back into their diapers “welcome to the family little brother.”
