She taught me many new and wonderful things. What surprised me the most was learning how hard it is to get a job as a woman. So Sheila introduced me t...o being a whore. I made enough to keep the part of my bills paid but not much left over. Then I found out about what a sugar daddy is. I met a trick who was much different than most of the men who wanted my ass and mouth. Most men just wanted me to suck them till they got hard enough to fuck me. Most wanted me doggie style or on my stomach, ass. I pulled off my jockey shorts and lay face down as instructed. Beth placed a bath towel over my back and buttocks. She leaned forward and put her upper body weight on my back. She explained that a warm fluffy towel is better than a cotton sheet as it holds more heat, absorbs oil if things get too slippery, and is softer. She proceeded to move the towel lower on my body and again press her upper body weight against my butt and then my thighs and calves. Even though the towel, I could feel. I took the whole of it in my mouth.My fingers were igniting her engine. Suddenly, she pushed me by her legs and pulled me over her and started smooching me wildly, her hand went down to my tool which was ready for action and guided it towards her wet pink love hole.I asked her to put a pillow under her ass to give me pure access. I kept my dick at her entrance and rubbed her clit with it. She asked not to tease her more and to fuck her right then. I obliged this time and pushed it inside her. Evolution has proven - Sex useful. Actually, we talked about this and so have guessed. Science has given to rational arguments.Sex has emerged from unicellular distant human ancestors more than a billion years ago. Almost all the a****ls (with very few exceptions) can reproduce sexually. Even jellyfish there male and female. Those a****ls that are deprived of the happiness (such as certain types of lizards), undoubtedly had ancestors that reproduce sexually.Why do we need sex?Sexual.
