I was barely gotten inside my home when my cellphone rang. I looked at the display and saw it was my sister Charlie who called. Charlie is short for Charlotte by the way, but she disliked her name so much everyone now just called her Charlie.

Ever since we were kids we have been tight. We has always been honest with eachother, completely. We has shared everything, our first kiss, our first fuck  everything we talked over and discussed with eachother.

When i was around fifteen or sixteen i found out i liked women in charge and shecwas the first to find out and tell me it was totally natural. I was just made that way.

When i answered my phone my sister sounded strange, so i asked what why and her answer shocked me a little. She was on the toilet taking a big dump.

Listen bro, i need a favour and it's a long shot but i can't ask anyone else. It is so perverted and nasty and i really can't imagine i'm asking you of all but... I have known for a very long time that you are a submissive and now i have done something really stupid. Last weekend i was out with my friends and we were fooling around and i ended up talking myself into this stupid bet with them. The problem is, the bet is for 5000 i don't have and i need someone to help me here.

Ok i said, i can lend you the money. No my sister said, i don't want any money, i need you!! Or rather the submissive you.....

How far have you gone with your girlfriends bro? Please tell me, what is the most perverted you have done?

For some reason i told her that my previous girlfriend took a dump in my mouth once.

Charlie became quiet, very quiet and i became nervous before i heard her voice again. How was that bro, tell me please? It was smelly and foultasting i told her after catching my nerve again. But at the same time the most erotic and intimate feeling i'd ever had. I never felt more alive or as close to her ever...

Would you do it again she asked. Her voice had now become thicker kind of. Sure i replied, with the right person. Someone i love and trust, yes totally...

You love and trust me right? Charlie asked...  Whoooa, that is incest you're talking of i said.. Yeah, but is that worse than eating shit little bro? I could hear her grinning on the other end. I guess not i replied...   I told my friends that i could find a guy, shit in his mouth and have him eat it all within the next two weeks.  Besides you i don't really know any submissives, and i really need this favour bro. I know there are tons of guys out there that would say yes, but i know someone who will really go trough with it and not just talk for ever about it. If you do this, you'll have me any way you want for at least three months after.... Deal?

Any way i want? I asked. Yes bro, any way you want. You can fuck me untill your dick falls off.....
