When she asked me to show her how to solve an equation or something, I’d lean down beside her and she would lean so close that our arms would touch.... could smell hair perfume; I could smell the shampoo in her hair. I started to get a hard-on the whole time she was with me! My mind developed fantasies of me bending her over my desk and fucking her for an hour. She’d moan and push her ass up to meet my thrusting. She would have orgasms that would leave her exhausted.And those fantasies did affect. I asked her "What's got you so fired up sweetheart?" She replied "You know damned well buster. Today is Saturday." I simply replied "Oh yeah. So it is."I told her "We need to go to the mall today to get you an acceptable outfit. We are going out to dinner tonight." Greg, that's not what I had in mind for tonight." Patience, little one; everything comes to she who waits." I've been waiting three days." And you're almost there."After lunch we went to the mall and entered an upscale dress store. A. Rebecca, the owner, decided that I needed a girl's name. So by the late afternoon, I was Annette Morris, Living Mannequin, at least that is what my nametag read. When I got back to the frat, and went to dinner in my new high-fashion jumper, I expected to get ridiculed. But the coeds defended me, saying I was really brave to walk a mile in my own panties. It didn't help that I looked better than most of them.Attending class in a skirt was a real eye opener. I got pinched, and fondled, and asked. . oh shit... David... David... fuck..."I pull my hand from around her leg and I gently thrust my index finer inside... it goes in so easy I'm not sure she notices. Two fingers... she notices that!... I plant my face on her clit and alternate between licking and kissing and sucking... all while thrusting two fingers back and forth... three... moving faster, much faster... fuck let's get them all in there! Four fingers and the tip of my thumb are ramming in and out of my sister's cunt!Vickie.
