'Stress reliever' had been a bad choice of role. The extra pay was offset by the fact that you were available at all times.
Alice hadn't slept properly in a week; whenever she managed to doze off, someone would yank her awake by thrusting a cock into her. And her ribs still hurt from a particularly frustrated janitor who laid into her with a baseball bat during 'Suspension Bondage Happy Hour'.
Oh, and the modifications? They'd included big fake tits, as well as replacing all the skin. And a big tattoo reading 'free use any time, no need to ask'. AND she didn't get let out of her original role, so she'd been spending the last few hours on her back unblocking a sink while men just thrust themselves into her holes and got themselves off. And they'd been wiping themselves off on the towel she was using to wipe her brow, as she discovered when she went to wipe it and smeared cum all over her face.

This job sucked. Even the splicecows had been better than this. Not, of course, that she could really go back there. For one thing, she'd never have been able to look her old friends in the eye after coming back, and for another the slurry would have been up to her chest without her damn legs.
And no, legs weren't 'cosmetic' modifications.
Alice dragged herself out from under the sink as the latest man finished, turning herself around and hauling herself up to lean over the rim of the sink; the last blockage was at the top, in the disposal unit. Which, according to policy, hadn't been turned off or even taken out of use, so the slop was half a meter deep. The blockage came out easily enough; someone had dropped a fork into the disposal and jammed it, causing the lumps to build up. Once she pulled it out, the disposal started up again, chewing through the layer of chunks in the bottom of the sink. Alice gave a sigh of relief, starting to push herself back up, but pausing as she felt hands on her waist. Another 'relief' job? NOW? Ugh!
Also, oh crap. He'd lifted her hips up, and she started to slip, thigh stumps flailing and kicking as her balance shifted and she started to slip. She put her hand down into the slop to steady herself, but it slipped in the layer of scum on the steeply sloped sides, dumping her head into the sink. She kicked harder, trying to push against both sides to push herself up, but was finally saved by her user grabbing her hair to pull her back onto his cock harder. She gasped, gulping air down, only to let it out in a piercing scream as her hand slipped into the disposal unit.
Just wonderful. Now she was going to have to learn to get herself off with the other hand.
