He was coming over to help me when he tripped and landed on me, he just managed too brace his hands on both sides of me to stop from body slamming me.... He was in a half kneeling half-straddling position above me, his warm breath in my face, my heartbeat doing fifty miles per hour. It was an eternity before we made a move to free ourselves from the embarrassing position. Instead of letting me up straight away as I thought he would a number of looks passed over his face I wonder what he was. Susan put her hands round Colin's neck and pulled him to her and I glanced up, almost enviously, to see them kissing passionately.I carefully eased myself almost off the end of the bed and then I was able to lie between Susan’s legs, and I started to lap at her pussy. She gave a low moan and I continued to lick her, flicking my tongue across her clitoris. Of course with Colin on the bed at the same time his groin was close to me and out of the corner of my eye could see his erection lying. I stood before Ronnie, naked. She then tapped on the bedpost with the whip and pointed to the complete outfit I was to wear.I first put on the black panties and DAMN, they were exciting. My cock and balls felt tingly. Sensational. Ronnie liked it too and gave my cock a couple more taps with the whippy thingy. Next came the halter top. It Felt exciting to my nipples and then a long, blonde wig. Ronnie stood back and admired her handiwork. She was pleased and FINALLY the thigh high black. I imagined that she was wearing the cloths and I wanted to see. I went near to the window. It was closed, but I can push the window door slightly without any sound. Surprisingly I could see that there was my sister’s husband. I thought they have decided to have sex after all people went to sleep. My sister directly went him with open jacket and half wearied saree. They were having sex. The position is she is above her husband and giving movements to him. It was awesome to me being first time to.
