We enjoyed ourselves immensely throughout the day andwhen it was time for my return, I decided to fuel-upand run the car through the carwash before re...urninghome. Jill, my sister, remarked that she needed somemilk from the convenience store and I invited her toaccompany me there.Jill is nice looking, nothing glamorous, with shoulderlength fair hair that is usually tied back in aponytail. Her build is that of a youthful size ten andI have always harbored some secret “what-if”. Margie gave Carol an approving look; she wore a simple black dress with spaghetti straps over her shoulders. The dress barely contained her jiggling breasts as she leaned forward to get out of the convertible.Both Vince and Margie were so distracted by Carol's cleavage that they didn't notice Milford approaching the car and opening her door for Margie. She glanced his way on hearing the sound of the door opening, saw him smiling, or better yet, leering at her."Hi Margie, I'm so pleased you. Lloyd – I, uh, don’t know what to say?” I completely got kerfuffled over this pronouncement, and sat down.Liz was still standing, having grabbed my hand as I started to cry.“There, there – David, don’t worry? I have absolutely no intention of telling anyone about this. I would like to sit down with each of you at some point and interview you for a study about Genetic Sexual Attraction. My thesis back in college was about GSA, and the chance to interview someone who followed though. Do you two. My breasts bounced upand down.I stood right in front of the mirror, real close. I tweaked my nipples,watching them harden and erect. They grew to almost an inch and a halflong. I rubbed them between my thumbs and forefingers. I felt waves ofpleasure course through my body. Boy, was I horny! I rubbed my hands allover my tits, paying particular attention to my stiff nipples. I bet Icould make myself cum just playing with them. I sat down on the bedfacing the full length mirror. I parted my legs.
