As I got ready to leave for work Mary Beth reminded me that we were going out with Mike and Alice that evening and they would be there at six-thirty t... pick us up. I told her I remembered and then left the house.Mary Beth was dressed and ready to go out when I got home. Even as pissed at her as I was I had to admit that she was one beautiful and sexy lady. I wanted her right then and there, but decided that it wouldn't be right to make love to her and then kick her out.Mike and Alice showed up. I thought About the looks we exchanged. I thought about yesterday. I thought about how he dominated me in his classroom. His hot hands touched every part of my body. His lips kissed my bare skin. His hips, oh how his hips connected with mine. His body kept perfect rhythm with mine. The thought of that luscious man having his way with me turned me on. The thought of his giant cock inside of me made me wet. I couldnt shake the though…I was driving myself crazy. I slide hand down my sweat pants. Leaning back on the toilet seat I spread my legs apart and started rubbing my clit. I closed my eyes and thought about my father and the dream. Rubbing myself franticly cum dripping down my fingers I was about to cum when I heard the stall door next to me bang shut. Afraid of getting caught I quickly stood up and flushed the toilet. Zipping my pants I washed my hands and ran out of the bathroom.I couldn't wait to get home and the bus ride seemed to take forever. I wanted to see him. I wanted. As expected, mother and Nicole - who was just beginning to take a sip from her cup - also decided to retire for the night into their respective rooms.I got undressed and then I waited for another half-hour before going to investigate in my sister's room.As soon as I opened her door I knew that the hot chocolate had taken effect. For one thing her bedside light was still on and although she had her nightgown on, she was lying in her bed and sleeping with a book - that she had probably intended.
