(There was a name mixup in the previous chapter, Alice is Jeffs sister)
After the couple has quieted down you continue watching TV for a while until you hear the door to Alice room open. As you turn your head you see Alice exiting.
"I gotta pee" Alice plainly says. Alice was completely nude, and you might guess why. Her hair was a bit messy and she had a small hint of sweat on her body.
"Sure I'll be with you in a second." You say and pauses the TV and get up from the couch. You follow behind your sister into the bathroom.
"Did you enjoy yourself" You casually and mockingly ask Alice.
"Stooop Jeff, thats private." she dissmisfully say. "But Greg is a very handsome man who... can handle heavy machinery..." Alice says wandering as you get into your regular stance.
As Alice turns aroundand starts to sit down, causing her cheeks to spread you are greeted by a white foamy pussy.
"And yes, I did enjoy myself ;)" Alice says with an implied smile on her face as she lowers her cum filled pussy towards your face. Her ass proceeds to engulf your entile face, and you mouth being filled with Gregs cum as it is being squeezed out from Alices vaginal canal.
"I know I haven't used you after sex before, this is the first time at home after all. But I figured that since Cassie and her boyfriend has been here, it would not be the first time. And besides you are part toilet part man, and toilets eat cum." Alice says and then moves her legs together and starts to silently hum to herself.
You agree to what your sisters says, There have been multiple incidents of rouge cum from different girls using you as a toilet. And no, you don't mind really. You signed up to be a toilet after all, a man of servitude. For example now, you are trying to help your sister get rid of cum by gently massaging her pussy lips with your tounge.
After a few seconds a few seconds of massaging the floodgates open up and she starts pissing into your mouth. A steady and determined stream. It mixes with Gregs cum giving it a unique taste. You gulp down every last bit of it as it comes. The flow of urine and relaxation of her bladder also released a blob of cum that falls down into your throat. As the stream dies down you feel her tilt to the side to grab some toiletpaper.
"I think this is a paper job Jeff, it's a bit messy". Alice says and then stands up a bit hovering over your face. But she does not wipe herself but instead gives you the paper, insinuating that you should do it. You obilge and takes the paper and starts cleaning her lower belly, thighs, asscrack and of course the outside of her pussy. Once you are satisfied you put the paper in the bin next to you. Alice stand up fully now, walks a few steps and faces you and looks down on her belly and crotch area to inspect it.
"Stellar job Jeff, you clean my body better than I do sometimes" She laughs.
"Anyway, I'll go tell Greg you are free. Be nice to him ok?" Alice with a smile and walks out
