*A lucario woke up, hands/paws were bound to a T rack and his legs were freely hanging. Something came and started to rub his butt, felt like hands casing his ass out trying to open his asshole, but there were pants in the way. The random hands went up to his waist and grabbed his pant line and slowly pulled it half off and out a bit. Once his hole was seen a huge tube with wet bumps on the edge that could spin and went into his hole slowly and deep, then the pants were put back on and was held front and back like it didn't want anything to escape or come out the pants*


*Then there was loud water like sounds coming from the tube and the Lucarios ass insides began to fill up with soapy water/milk/cum and then when his ass was full and his belly and insides getting a soapy cleaning, his pants were filling up and then hand were trying to keep it all in so his underside and front (Dick) were getting cleaned, but then more hands came and held the bottom ends so the fluids didn't come out there either*


*Finally the pants could not hold anymore fluids and started to break in places, he began to lactate the extra fluids. Finally as well the pants just plopped to the floor when the hands just let him go and now he was nude, dripping, and swinging back and forth. Another tube came to his maw and forced its way into it and started feeding him calming fluids and sample/harvest/suck up his stomach fluids and then showing in front of him a machine that shaped like a baby but the diaper area was being filled and pressed thin*


*The machine stopped and the diaper was taken out and the Lucario looked at it, it looked like it was dripping full time, on the inside there were all little wet brushes and a single stick brush that went into the asshole, (There was also a dick cleaner in the front that enters through the sheath). The Lucario's legs were pulled up by some unseen force, not a machine hand or the like, and the clean clear wet diaper was put under him, his body trembled like he was in a pond of water*


*The ass ate the stick brush and it extended inside him until it was totally full in his ass, (Dick sheath was the same as well). His insides began to fill up with force fed stuff and started to create "dark matter" which the brush started to clean right away, it started to spin and open his ass buns wide to the sides of the thick diaper and spout wet wipe and soap in the ass*


*Whenever the diaper colored up it inhaled like breath the colored areas then exhaled soap and stuff, that made the diaper grow a bit. New hands grabbed his rear end and massaged and spanked it making it drip or splash out liquids onto the floor. He now could sense he was not alone*


*A female Mewtwo with what looked like a wet diaper on her groin and bra areas leaking profusely. She came from in behind and stuffed her face into the ass of the Lucario's diaper, but then she began to lick it, her tongue was coated in some kinda cleaning fluid and was playing with his diaper. She got herself all wet with what was dripping out of the Lucario's diaper rubbing his ass cheeks through the diaper*


*Then she reached up and tore off the diapers letting the deluge cover her, she licked up some of it, spiting it back to the Lucario's ass. Then off to the side she put on a half mech suit that put brushes on her hands and a dual-tube sucker on her face, it sucks anything and then cleans and feeds it to whoever equips it. She grabs the buns and starts the brushes spinning and starts to wash the Lucario's ass*


*Her mask sucker was like a tube inside of sucker rim, she stuck the bendy rod into the ass and the sucker fitted her face onto his ass buns which continued to open three ways, his insides started to come out and Mewfii started sucking it. Her hands were waxing on and waxing off the bum*
