Part 1.

"I don't see what makes this any better than taking a long, hot shower. I think you just got a thing in your head and now you won't stop bothering me until you try it out." "It'll be like a sauna! And you don't need to wait for the shower afterwards since you're right there! You wouldn't imagine what people would give to get this kind of 'luxury spa' experience. Probably. Haven't asked around but the concept is pretty exclusive."

...

Shlork. "I don't think a sauna is supposed to be this wet. I think a better analogy is 'steam room' but in those there's something separating you from the liquid." "Nngh. Is that a complaint?" "Kind of. I'll try it get further in and see if it gets better..."

Part 2.

Shlnk. Grwp. Sllk. Myles was taking his time, getting comfortable between efforts to fit more of himself inside Lyra's loins. She shuddered every step of the way.

 "Can you do it any faster? -Mmmmnh! Never mind! The pace you had was fine!" "See, there's another reason this isn't a common practice. It doesn't feel like you're really trying here either." "Don't patronize me. I-I'll show you 'trying.'"

By this point Myles was only as deep as his hips, holding Lyra around the waist to keep upright. She took a deep breath and, holding her jaw tightly closed, pulled the rabbit into her cock with her internal muscle. SCHLRNK. Myles lost his grip and was turned around, legs folding up inside her as he found himself sucked in already to his chest.

"Okay, I understand! I think I need a moment to adjust. Um. There's not much space in here." "I really don't know what you expected. Hold on." "Hold on?"

Glrrk.. Glrrk.. It sounded like Lyra was winding up some kind of biological spring inside herself.

GLRRLP.

Myles was pulled in entirely but for his head. His chimeric captor, as she now was, smiled down to him, then pressed the head of her cock against the foggy glass, pushing him in to leave only his ears flopping out. His frame of vision was reduced to a ring, and it was incredibly warm all around him.

"That's better. That's better..." Lyra was panting. It had been more than a minor effort.

Part 3.

Lyra found it hard to keep her footing in the shower as the floorspace became suddenly crowded and ever more slippery. Myles was pushing in all directions trying to find a comfortable position and his complaints could be heard through the taut skin and fur of her sack, albeit muffled.

"It's still just as wet, but a very different kind of wet..." Lyra heard and felt him slosh and shlp around inside her. The pleasure was making it impossible to maintain decorum. Myles was feeling similar about the situation - it was impossible not to be aroused by the experience, especially with how much his body was getting kneaded all over - but he was better at hiding it. The physical barrier between the two helped.

Lyra was finding it hard to keep her eyes open. The water didn't bother her so much as Myles constantly fidgeting and squirming. Glnk. Gwbbl. "This isn't going to go as we planned if you won't get comfortable in there... Ah!" Lyra was cut off as a sudden kick from the rabbit caused her to slip, thumping to the floor with her legs bent to fit the shower walls. Her balls sloshed and their occupant tumbled inside. Slgrpsh! Mrnph!? Myles' face was shoved into the tight skin near the base of her cock. His mouth was filled with the fluid sloshing around in her sack and it made it hard to form coherent sentences.

Part 4.

Lyra could feel that she hadn't come to a full stop - she was still sliding towards the locked door of the shower, and with Myles struggling to right himself inside her sack she wasn't sure how she would finally end up. The heat of the shower - which she was well adjusted to by now - was just cooler than the furnace inside of her that Myles was experiencing, and that furnace was only getting hotter and hotter. You should really calm down... She thought, but didn't say, as she was feeling rather foggy in the head right now, too much so to give instructions to the rabbit involuntarily getting her off. Gwwrrrp. Glrrgle. Blurp... Myles crossed the threshold between coming out of this as a solid and as a liquid, though he couldn't yet feel it. "What happened? Did you turn up the heat on the faucet? I can barely hear you... Mmngh, get this stuff out of my mouth..." Slshh. "Trying something... Hold on... Mgh." Lyra could make that part out. "Huh... Nnnnff... Don't make... Ahhn... Sudden movements... Right now..." Lyra's fluids were churning so vigorously that it drowned out her voice. Myles stretched, and the two tumbled over backwards - glworsh - leaving Lyra pressed ass-first against the glass with Myles suspended above, her tip hanging right above her face. Pre dripped onto her lolling tongue as she tried to make out what had just happened.  The rabbit was further disoriented, kicking and squirming to find which way was up to no avail. Mlphh! Hrph. Mrrph. "Hnhh... You're in the... Perfect spot... Mmmmhh! Just don't mooove so much and InnnNGH! I just need to..." Glosh. Glpshl. Blbbl. Sglrsh. Lyra was too overwhelmed, the panicked bunny squirming incessantly against his better judgment, and braced herself for what she would do next.

Part 5.

Myles was in an extremely tight hold that only resisted more as he struggled. Speaking was difficult and doing it made the taut sack seal even tighter. Slrshl... Gwoooorp... Grgle... Lyra was panting, and craned her neck to get close as she could to the imprint of the bunny's ears.

"Too much... Myles, love you... Stretch out as hard as you can for this one, alright?"

Myles obeyed the muffled request, streeeetching his limbs as far as his cum-soaked, semi-solid muscles would let him. Hrmnnnnnfh - The imprints strained and pressed into the glass walls... Then Lyra grit her teeth and clenched her muscles, compacting the struggling rabbit into two hot, tight orbs of chimera nut-sludge with an overwhelming SCHLRNCH. Lyra relaxed her jaw and breathed heavily, head still fogged with pleasure. Her balls relaxed, and they filled out to the walls of the shower, completely stopping the water from reaching Lyra's head. Myles' work may be done, but Lyra still needed to deal with the churning, bubbling, groaning cauldron of rabbit soup suspended above her head, and she had a good idea of how to do it.

Part 6.

Lyra craned her neck upwards. She had a moment of respite now that Myles’ struggles had calmed down for good, but there was still something else that needed immediate attention. Her cock was stiff, pressed into her gut, and though she couldn’t move her wings pressed against the walls she could still bend her back forward just slightly and - *mmmngh* - put herself an inch closer to orgasm… She had to be careful here, otherwise the *churning, bubbling* rabbit product would be wasted. Angling her jaw open towards the ceiling, Lyra *clenched* her gut muscles, squeezing a spurt of hot black-green sludge right down her throat. She swallowed the thick fluid greedily. It had a flavor reminiscent of fatty, marbled meat, but gamier - just what she expected from such a well-fed rabbit, though he didn’t look it at first glance. Lyra *clenched* again, and a thicker two-toned spurt of liquefied bunny shot into her gullet. Swallowing again, she could feel her stomach starting to work on the protein-rich goop, turning Myles into usable nutrition for the beast. *Rrrrumble… Glurrrrgle… Gwurp…* Kicking into gear caused Lyra’s gut to get unruly, and she was having trouble controlling how much liquid she was pumping at a time out of her suspended and still-churning sack. Finally, she reached the tipping point, and the hot fluid started filling up her maw faster than she could swallow, spilling out onto the tile and coating her hair and feathers. Her gut was expanding, and her stomach *churned* and *gurgled* incessantly as soft fat pushed out from either side of her throbbing member.
