Put a dog collar and leash on her and dog walk her on all fours to the toilet and have all your friends come over and take turns to use her as a human toilet. Place her face sideways on the seat and everyone piss in her mouth and face.
She can stay there until everyone is done, then grab her by the hair and push her face into the piss toilet water and watch her drink like a dirty piss ***** should.
Then dog walk her back to a space in your living room, where all your friends are sitting around jerking their cocks to a hot porno, and as one is ready to blow, you lead her by the leash to her bull and present her mouth for his cock's pleasure to cum in her mouth. She doesn't swallow the load, but saves it in her mouth until she is full.
Each friend shoots his big load all over her mouth, most of it in her mouth and the rest a nice decoration around her cheek and drippings off her chin.
Once she has serviced everyone it's time to swallow her mouthful. She then crawls over to each cock she had the pleasure of swallowing, and cleans the cocks with her mouth and politely says thank you to the bulls.
She is then laid out on the floor to be used and a fuck pig as they feel whilst enjoying some beer and porn.
When someone feels like a fuck, then can fuck her in her ass or pussy. When they feel like a piss they just get up and piss all over her. Anything goes. Piss her mouth, ass or pussy or her entire body.
She loves the humiliation and degradation. It actually turns her on to be used like a fuck pig and piss *****.
