As Sara left the house you figure there is no point in you staying in the bathroom as you are home alone. You figure it might be a good time to catch up on some tv-series. So you exit the bathroom and goes to sit in the couch and fires up your favourite series to watch.
The hours pass to your mindless fun; watching one episode after another. After a few hours you hear keys in the front door and the handle turning.
"Hi Jeff, im home and I brought Greg, I hope that is ok" You hear Sara yell from downstairs.
"Yea thats fine" You yell from the couch. Hmm, Sara brought her BF you had only seen pictures before so it would be nice to meet him and get to know him a bit better, it's allways intressing when men come and visit after all.
Soon you see Sara followed by Greg enter though the hallway. "So, this is my brother Jeff. Apart from that he is one of the ones who like being a toilet. You get spoiled by having one in your family I tell you." Sara says
Greg is a fairly slim but muscular guy. Around 180cm and blonde. You shake hands and exchange pleasantries, he has a firm handshake, that one of a buissnesman.
"Well Greg, what I really wanted to show you is my bedroom..." Sara says trailing with her hand to Greg. He gets the hint and follows Sara into her bedroom and they close the door.
Oh god, you think. Is Sara really going to fuck that guy with you in the adjacent room? I mean come on, even if you gave up all your dignety by becoming a toilet you never thought your sister would invite over a guy to fuck her. But this is the life you choose. You have eaten cum before, all be it, not from your sister, and not this fresh. The more you think about it though, it would be a good bonding experience.
Not long after the pair disapeared into her room you start to hear moaning. Not wanting to creep you turn the volume up on your series hoping to drown it out, but to no avail. Saras moans just gets louder and not long after you her her bed creaking and Gregs grunts starts to be audible until it all dies down.
Your assumsion is, the deed is done and you wonder what both of them will require from you.
