Only then did I realize I was getting an erection. I gave my cock a tentative rub through my pants, but it felt wrong to get off on what I had inadver...ently witnessed. Instead, I settled at my desk and tried to start on some homework. It was not easy with thoughts of the scene in the living room dancing in my head.A soft knock on my door startled me after several minutes.“Come in,” I called.Tonia entered, her clothing back in place. There was a slight flush to her face, perhaps post-orgasmic or. Her own fantasies, though she’d had them for as long as she could remember, continued to embarrass her. She knew that it wasn’t proper of her role, to fantasize about her mistress like this. Her life was one of service, not of pleasure. It was not her place to imagine Sansa naked, or to ever think that she was worthy of being touched by the young Stark girl.Worse, she normally contained these thoughts for when she was alone, touching herself. She’d imagine that it was Sansa’s hand between her. Then I massaged her foot and traced my fingers over the base of her foot. She got tickled by this and pulled her leg away. I then split her legs a bit and sat between her thighs and began running my hands over her back and then her butt.I reached her butt crack and glided my fingers down it over her arse hole and then went further down to her pussy lips. She reacted with a jerk when I touched her lips.She said ‘what are you doing…you should not be touching that.’ I did not stop and continued. On his way out, Dad asked quietly, “Would it be okay if Joshua and I joined you two?”“Of course, that way I can invite Greg, Bob and maybe Linda to join us too. Just let me know. Oh and FYI, Sherman is NOT invited.”The grin and wink he gave me confirmed that he knew the score, he too was growing weary of playing hide and seek. I didn’t care if Sherman had heard us or not.As it approached 10:30 PM, all of our friends decided to call it a night.It’s funny how that seems to be a nearly universal.
