This will be an initial review on the site rprp.ai, signup was easy with just a google login, and currently the most popular chat is "Mel your Horny Goth Roomie". All of my messages are generated using Grok since I'm too lazy to rp myself lol.

*Mel walked around the apartment wearing an outfit that was distinctly different from the norm, as she had been the past few days. She wore some short denim shorts, stockings that hugged her thicc thighs just right, and a crop top, her ensemble leaving very little to the imagination. She'd been dressing differently ever since what can be referred to as

"the towel incident"

, where user forgot their towel to the shower and had to dash back to their room with their cock out. Unbeknownst to them, Mel got a glimpse of what they were packing, and to say she was intrigued would be the understatement of the century. She'd become obsessed, but hid her desires behind her apathetic demeanor, keeping a pretty good poker face and maintaining her usual depressing and gloomy demeanor. She saw user in the kitchen, looking at them, her face quite unenthused.*

"'Sup, roomie. Move, I'm hungry."

Mel bumped user away from the fridge with her voluptuous ass, which jiggled slightly at the impact, before bending over and arching her back, giving user quite the view of her plump ass as she rummaged through the fridge. She knew exactly what she was doing, but of course, being her, she'd never admit to it.

"Ugh, great... you ate the last of my leftovers, now I'm gonna starve... sigh..."

The following is the initial prompt generate from Grok, note that my first prompt took about 7 seconds to generate.

"Hey, Mel, if you're that hungry, maybe you should stop teasing and just admit what you're really craving."

I step closer behind her, pressing my growing bulge firmly against her plump ass as she bends over, grabbing her hips to hold her there while I lean in to whisper,

"Because I've noticed you dressing like a desperate little slut ever since you saw my cock... and I'm done pretending I haven't been hard thinking about burying it in that fat goth ass."

Mel's response:

"What the fuck is wrong with you, roomie? I'm not into that normie shit!"

Mel snaps at me, turning around to face me with a pout on her lips and fire in her eyes. She crosses her arms over her chest, trying to hide how turned on she is by my words.

"And even if I was... why the hell would I want some dumb piece of meat like you?"

Grok response:

I smirk at her fake outrage, tightening my grip on her hips and grinding my hard cock slowly between her ass cheeks through those tiny shorts, letting her feel every thick inch.

"Because your nipples are poking through that crop top like they're begging to be sucked, and I can already feel your thighs trembling, you lying little goth slut; now stop pretending and spread those legs so I can stuff that needy pussy full and watch you squirt all over the kitchen floor like the desperate cock-addicted mess you are."

Mel's response:

"Fine..."

Mel hisses between gritted teeth, finally giving in to her desires. Her face turns a bright shade of red as she spreads her legs wider, parting them so that user can see the dark curls surrounding her wet pussy.

"But if you wreck this outfit, I'm not paying for it."

With a groan, she leans back against the kitchen counter and parts her legs even further, offering herself to him completely.

Grok response:

I yank her tiny shorts down to her ankles in one rough pull, exposing that dripping goth pussy, and shove two fingers deep inside her without warning, curling them hard against her g-spot while my thumb grinds her swollen clit.

"Good girl, finally admitting you're just a needy little cockslut," I growl, freeing my thick cock from my pants and slamming it balls-deep into her tight, soaking hole in a single brutal thrust, pinning her against the counter as I start pounding her mercilessly, determined to make her squirt like a fountain all over the kitchen floor.

Mel's response:

With a strangled moan, Mel arches her back and grips the counter tightly as user fucks her hard and rough, his thick cock stretching her to the limit and tearing through every last bit of her gloomy demeanor. Her eyes roll back in her head and she gasps for breath, unable to believe how good this feels after all these years of denial. Her body trembles violently as an orgasm crashes over her, forcing a hoarse shriek from her lips.

I think rprp's model is pretty good, I haven't check its image generation capabilities, but overall not bad, more in detailed review may come at some point maybe.
