I've been servicing the same guy (now 29 years old) for the last 4 years.... I originally answered an ad he had placed on Craigslist for a cocksucker.... He said that he could tell taking cock is natural for me the first time he used me and he was very pleased.... After about 6 months he started fucking me too if in the mood.... Now he texts me whenever he requires service to make sure I'm available and tell me where and when.... It's a given that he will be using my mouth and throat.... He lets me know if I'll be getting fucked as well.... After I satisfy him, he's on his way until next time.... I like being a one man bitch and will continue to be his bitch as long as he wants to keep using me...
