" Oh, you're smoking hot, step-sis. Fuck all those others in the squad; you could be the whole team, I swear." I know, but quit talking; you can have ...the time of your life without words, you know."I nodded and kissed her again. I felt my schlong take the deepest shelter in her snatch that I could possibly imagine as I kissed her. That kiss only lasted for a moment, but then I arched my back up again.I grabbed her thighs and had my dick thrust a little harder. That got her boobs to move a bit. As I hadn't intended to do any study with her, I hadn't brought it with me and answered, 'Oh . . . I forgot my book.'She knew why I hadn't brought it, due to the note she had handed to me yesterday. However, I was surprised when she said, 'Well, atleast I have a spare,' as she stood up and walked over to the small pile of books underneath the table in front of the sofa where we were sitting. She slowly bent over to find the book we were studying, and as she did, she revealed her black lace. Last night while all the family was in the living room and in the balcony she went to the back of the house to look for some reaggeton music she had copied in a USB key. She was wearing a low cut tank-top, and a short skirt. Samuel followed her and when they were out of the look of the others he jumped her, kissed her passionately, and caressed her breasts and her tights. She kissed him back and let him touch her. She was very horny and wanted Samuel to make love to her right there and then.. .." he trails off meaningfully, producing a pair of vibrating panties. "This is a pair your Mistress modified special. In addition to the usual tricks, these have an array of sensors to keep you stimulated just as you are right now; about to go off and aching for more all day. Or until we decide you've earned a little reward."She moans as he carefully unlocks her ankles one at a time, then pulls the diabolic panties tight up over her hips, the thin fabric of the thong almost undetectable.
