After staying in the bathroom for a while it seems like the movie ended. The girls start chatting about what they thought about it and what to rate it on imdb. Having no intreset in joining the conversation you stay put.
The chatting continues on for a while until you hear them staring to disperse. Cassie poked her head in the bathroom to say goodbye before leaving, the otherones just yelled through the walls. When everyone had left there was a eeire scilence, sometimes interupted by your sisters steps, who was still home.
looking at the clock on the wall you see it's 23:00, your sisters bedtime, guessing she will come through the door any minute your mind wanders until she opens the door and steps in and locks the door behind her. She just gives you a polite nod and goes to the sink and takes forth her toothbrush and starts brushing her teeth. Doing a little dance to pass the time she walks towards you. Knowing her routine by now you stand on your knees and open your mouth as she aproaches. She takes out her toothbrush and spits the white foam into your mouth with deadly precition. The minty flavour fills your mouth, you would not really say it's better than Saras piss you had before, just different. You can't really decide if you like toothpaste or not, it's not like you need it. You hardly consume sugar, and what do you need teeth for anyway. But then again, it seems like users like your sister enjoys your breath more when you had some.
Your sister then walks over to the sink and rinses her toothbrush and places it back in it's place. Swiveling around and facing you she reaches for her pjyama pants. You know very well what is to come.
No words needs no be exchanged here as this is the same routine as every day. You get on arse leaning back, using your elbows as support not to fall. Face straight up and mouth open. While entering this position you can feel your sister step on left thigh with her left foot, and then comes the twisting motion. She swivels on her left leg and in one motion you see her bare ass and pussy enter your view and a second later blocking your vision. She now sits comfortably on your face with her pussy already positioned on your mouth, her feet planted firmly on your thighs for support.
You can feel the heat and aroma coming from her sex, an intimate detail not many know, but you know it by heart. You can feel her every hearbeat, her every breath. She lets go of a small sigh followed by the familiar relaxation in her nethers. A dilluted stream of piss exits through her making it's way directly into your mouth ready for you to enjoy. It appears she must have drunk a lot of liquid tonight you figure. She knows the limit of you so she tries to drag out her urination for a bit. She goes on for 40 seconds in a leisury pase until she is finished. When she is finished peeing you have to clean her, you extend your tounge and starts going at it. The good part for users about using a human toilet is that there is no urine in unexpected areas. Unless you are Sara.
When you are content you can her bodyweight shift and more force being put on your thighs as she starts to stand up. Your eyes no longer are covered and you see her ass being lifted up. Without turing around she pulls up her pants and panties and walks forward.
"Thank you for your service as allways Jeff. Sleep tight." She says and exits the bathroom.
Time for bed then. you think to yourself as you lay down on the floor looking up and close your eyes.
Tomorrow will be intressting
