Your girlfriend left you alone in the bathroom, are you just going to sit here and await new visitors?
I guess so.
However you were alone and you felt that you needed to move around a bit. Luckily you were mobile. You inspect yourself in the mirror and see no real difference from your old self. You still have your face and your mouth and throat looks normal. Wonder were the waste goes?
While inspecting yourself in the mirror the door opens and your sister enters. She has a phone in one hand as she enters and headphones on. She locks the door behind her and puts her phone on the sink completely unfaced with you standing infront of the mirror staring at her.
Humming to some tune she gently shoves you to the side making her the center of attention infront of her mirror. She opens a cabinet and pulls out some lipstick and applies it. You never really felt any attraction to your sister, but seeing her standing infront of the mirror would have some people drooling.
She smacks her lips and puts away the lipstick and turns to you. Still humming to the music she takes you by your shoulders and guides you to your corner of the room. Pushing you down to the floor you are now in the same position as you started. She spins around and places her ass on your face, without removing her pans or opening your mouth. Removing her sock she placed her heel on your cheek and soon you hear nailclippers. She goes at it for a while, changes her footing and does her other foot.
She then stands up, towering above you, her toilet. Pulling down your cheek like your girlfriend did, but this time there isn't any toiletpaper coming it's a handfull of toenailclipping. She brushes them of her hand and they land on your tongue, sharp little buggars. looking down on you and facing you she proceeds to pull down her pants, turns around and slamming her ass onto your face. Wasting no time she shuffles to form a seal with her pussy and your face.
Then hell brakes loose, a torrent of piss flows form her pussy. If this was before the modification you would shurely be choking and gagging from the amount off piss. However you magically gulp down everything. After a solid twenty seconds off a piss jet striking the inside of your mouth it subsides.
Then...
