Rather well...

Specimen 9's eyes fluttered open and she released a quite little yawn. She found herself in an oddly comforting place, a pen filled with a nice stack of hay next to a tub of water, though she was confused by suction cups attached to her nipples and a tube around her cock, both attached to clear storage bins of some sort. She wiggled a little and released a gasp from the sensations of her movements. It felt odd not being in a room with those nice little white coats petting her or petting one of them, Slowly, she felt a tugging on her nipples and the device around her penis began to slowly pulse, her cock feeling as though it were sinking into an extra slick pussy. She leaned on the fence, gently thrusting her hips and inching her hands to her breasts as the machines went to work. Specimen 9 wasn't sure of what was happening but she sure wasn't making any complaints. To stimulate her self further, one of her hands went back to take a deep dive into her anus, stimulating her prostate and making her cock cum some more.

Over the next few days, Specimen 9 would be visited by worker to deliver food, water, and occasional cuddles while the machines would start up at certain times of the day. It was nice but it would be even more nice if she had some company though...
