I didn’t know what was going on but I saw the girls licking him and holding their mouths open. I slowly licked her slit from top to bottom. Now comes the strange ‘twilight zone’ part. I couldn’t see it happening but then his girlfriend got on her knees and put her pussy up to my sisters mouth and started rocking it on her. Next, feeling each others tits. For some reason I got a sex thrill by watching all this. My mind drifted back to that night I watched him lick my sister and his girlfriend. She was all for that. She came in and we did our usual feel ups. She walked in on me in my shower and we went wild feeling and licking our slick bodies in the warm water. I had always wanted to do that….. Now things changed between us. She kept it up as I began to build an orgasm.
