Sydney took a shower and came in, then she said 'Alex i have got something to tell you'. I pretended to be surprised, didnt show any feeling, so just ...old her to go ahead with out any suspicious on my voice. 'Well, remember those things you used to tell me about seeing me with a stranger man?' was exploding inside and acting like the most surprised and calm person on earth said to explain more. She said that she felt the right to try it, she confessed she wasnt that much turned on by that. I was glad the situation hadn’t turned sour and that we both were trying to avoid confrontation or at least be silly and laugh about it. We both knew that one of us is eventually going to win the battle and be left alone to watch whatever the person wanted. I was hard headed and so was Steph so the battle was on, I was too horny that night to give in and masturbate to imagination in my room. I presume Steph had it the same way.Looking back at the TV set I started to blush knowing that my sister. Distinctly arousing..."Is there no way round this?" She was trying hard to hold on to her dignity, and keep the desperate note out of her voice. But she wasn't quite succeeding. I looked her in the eye, then up at her hair for a moment, then back to eye-contact. It always works - an unmistakeable signal.She responded by looking me up and down - also an unmistakeable signal. She was no fool. She knew this was the moment when a girl's gotta do what a girl's gotta do - and pretty quickly. She holds her knees and adjust alignment. She wants this in and out style ride. She loves the feeling of the rim. As the thick rim hits her g spot and in and out of her lips, the nerves drive her over the limit. With in a few minutes she is mid orgasm. In and out I dare not stop nor change speed. Her juice splashes sound and she moans, "ooohhh" Softly and I know what's coming. I cover her head with a pillow. I take her legs. She wants me to stick her hard and pull out. The sound of her tight.
