As we kissed, her lubed up breasts were gliding over my chest and felt wonderful. Her nipples were rock hard and she seemed to love it when I had them...in my mouth.Elsa jumped off me and demanded that I get on top and fuck her. She lay back and spread her legs. I got on top of her and teased her by rubbing my shaft along the outside of her pussy before going in balls deep. I was fucking her nice and slow, feeling every centimetre of her hot pussy. She grabbed me close for what I thought was. She surprised me when we left his office by linking her arm in mine and whispering softly,"I'll give you enough money to start up your own courier business if you like Billy" Why would I want to do that mum?" I replied and held my arm tightly against myself so as to stop hers being withdrawn,"Well, you know, last night" Let's have a coffee mum" and I steered her into a little bistro,"I'm seventeen tomorrow mum, I'm not a boy any more although the law says I am"She nodded in agreement,"I know. He pressed the head of his cock against the entrance to her pussy then with one smooth thrust Andy slid his cock all the way in to the hilt. Shirley let out a small moan as he entered her and I let out a moan of my own as I watched him sink his hard cock deep into my wife's pussy.He stayed there for a second or two, buried deep inside her then grabbing her by the ankles he held her legs outstretched in a wide V.Sliding his cock out until only the head remained then back deep into her pussy Andy. Their professions allowed them to make more money with that kind of schedule. Anyway, that left me to do most of the house work, take care of my little sister and still manage to stay on top of my school work. What it didn't allow me to do was have much of a social life,especially in High School when my hormones were racing, and I needed interaction most.Don't get me wrong I love my sister very much and enjoyed spending time with her growing up, but I never had much time to be a teenager..
