My exploration of the female body was strictly limited to content seen through a computer screen and occasional spying on my step-mom. My step-mom was...the classic professional. At forty-six, she was an attractive woman who stood five foot five with brown hair, small frame, and big tits. She dressed well, opting to wear skirts and heels to work. I had started spying on her when we moved into our new house several months ago. Discovering an opening in my closet wall, I could see into her private. She loved the entire experience of seduction and of going after what she wanted in the area of sexual conquest and getting what she wanted. This time, Monica wore a very sexy bra and thong and then she put on a rather short skirt and matching jacket with a sleeveless, low-necked top underneath it. On the surface, with the jacket on, it wouldn't appear that Monica was dressed that sexily but when that jacket came off, no man would be able to resist her. Monica also picked out a pair of thigh. Anus licking? Likewise. Activities involving poo? Definitely not. Bondage? Okay. And so on. ML will be about, if not actually in the room, to settle any grey areas. We will learn "on the job".Guests like to be thanked for using me. So I must be gracious and genuine when doing so. I am not allowed to initiate any activity. I wait to be asked and wait for ML to allow. Erections are not only acceptable but encouraged. The guest likes to know that I am enjoying their demands. A good flow of pre-cum. What a awkward fucking breakfast. And the whole fucking time she just laughed and stared at me. But that night was when she had her fun. Me and my sister had always shared sex stories with eachother just for shits and giggles. but that night she asked if she turns me on. almost immediatly i replied no your my fucking sister. she said dee its alright i looked at your dick before you started fondeling me. oh shit my sister is a nymph!Anyways, she begin to take her shirt off and told me to touch.
