Heavy breasted and full hipped, she was a sight for sore eyes, and after our first nervous dance she loosened up and we began to grind into each other... She pressed her pussy into my crotch, raised her hands above her head, and closed her eyes, swaying to the music. I grabbed her hips and pounded right back. I could feel the heat of her cunt through her thin sundress, and my cock jumped. She smiled, and after opening her eyes and looking right at me, grabbed my hand and led it under her dress.. :-) My parents were always very open about sex as a rule. I guess it came from the early 70's ,free love time that they grew up in. My mom would walk around in just a bikini or her pantys & bra on on hotter days,which in Texas happens a lot. So it wasn't unusual for her to be seen outside doing some chore in a bikini bottom with her gorgeous tits free of any cloths. So I guess I noticed my sisters doing it too so to me it wasn't a big thing to just strip my shorts or little dress off down. At that point, she smiled and removed her right hand from my throat and then hauled back and slapped me across the face. I was surprised but I didn't try to move away. She still had a tight fist full of my hair and she shook my head, pulling my hair, and then slapped me hard again.I felt my face burning and feeling a little numb at the same time but I just accepted it and waited to see what she would do next.I was surprised when she released her hold on my hair and then pulled my lip down with. Her parents were asleep when we came and the light in her brother’s room indicated that he was awake. I almost forgot to mention that we made an awesome badminton mixed doubles team. It is hard to beat us. Anyway, I entered my room to discover that my cousin brother was attending a conference call with people in his office. There were probably people from different geographies and hence the odd timings. He gestured to me to keep quiet and told me that the call will go on for a while.I silently.
