Out of a side room walked Mrs. K, wearing a very short robe that barely covered her shapely ass. Her sexy long legs were so beautifully tanned, in con...rast to the white robe. I could see her turning and talking to someone, and her husband appeared. She playfully pushed him against the wall and kissed him. I was enjoying their make-out session but definitely wanted to see more. As if she were reading my mind, Mrs. K turned down the hallway and stared straight into the mirror with a teasing smile. . Are feeling good....are you ok......?"‌‌I asked my sister if she was embarrassed about it.... apparently she was little embarrassed and she just turned around and started to leave the room i said nothing to and she left...... All day we just ingnor eye contact with each other. We started to stay dressed it was a little wired to see her dressed in house and also painful not seeing her naked..‌‌For 2 days this ignoring sessions were continued. Our mother saw this not talking to each other thing. That night, while we were eating dinner, mom asked me if I was going to Gail's party. Dad's head instantly popped up when I said yes. "I'm getting tired of staying at home, and if I have to dress as a girl, then I might as well enjoy it. I'm going to wear the blue dress again." I said it, but only mom and I knew it was a lie. I wanted to go, sure. But it wasn't because I had cabin fever. I wanted to go because I had decided that I needed to prove my newfound femininity to myself. If what I was. "No Princess, I just dont want to cum before you" I answered."Well, you wont because I have not cum yet" she said, "Ugggnnn" she groaned again, and began to squeeze her tits, lifting one she began to lick her own nipple - she likes having her nipples licked - and her groans increased slightly. After a few more minutes it was getting dangerous for me, at this pace I just knew it could happen at any moment, pre cum already had trickled out of my cock.Her groaning became louder, her breathing.
