I can feel the nipple stiffening in my mouth as I continue sucking; now switching back and forth between breasts as I fumble to undo her jeans.Despite...her positive response, I am quite nervous that she'll stop me at any moment so I don't let up and don't waste any time. I finally unbutton her jeans and peel them down past her hips and ass to reveal a sweet little pair of yellow cotton panties. They look so innocent against her fair and lightly freckled skin, but I can feel an incredible warmth. In hindsight I should of said no but I didn't realize my weaknesses---what weakness do you mean young man? My mother is only 5 foot tall but has a 38DD chest and an ass that could of been a star on soul train. When I reach under both of her armpits with mine and lifted her from her wheel chair onto her feet she hugged me to hold on. The top of her head fit under my chin as momentum brought us together. I could feel her nipples pressing into my lower ribcage and i instinctively drew her in. Still, the jab of the knife had hurt. Until a few weeks ago, she had never felt intense pain.Or intense pleasure, for that matter.She opened the front door and looked around. A retired professor she had seen around campus was walking his dog. He nodded to SG. She waved vaguely and waited until he had passed.Where should she go? She knew she wanted to expose Toopermann and Regina for the sadists that they were, but that would almost surely involve blowing her cover. She also wanted to get even. Too late the realized just what was going on.From deep in the shadows, a silent pair of eyes watched.The encounter had just turned very dangerous and very deadly. They twisted and contorted, acted and reacted, each trying to get the other to make just the tiniest mistake, for their very existence depended upon it.His cock was buried deep in her body. He knew that he could not withdraw as that would be giving her the advantage, he knew that he could not cum as that would lessen him. She knew.
