About half way through the movie she said she was cold so I grabbed the blanket of the bed and put it over us she took the move by cuddling against me...my right hand went behind her back and rested firmly on her ass. Her hand was on the inside of my thigh which was all it took to get me hard as a rock I started to move my hand in circles on her. Ass putting just enough pressure to make sure she could feel it but not enough to make it seem like I was some horny school nerd that was just trying to. “Want to come over tonight, my mom’s hitting the bar with some friends?” I asked as our lips parted.“Sure,” she said as she gave me a little smile and walked away.As I reached the car Jessica asked me “So, I guess she is coming over tonight since moms going to the bar?”“Yeah she is, but it’s none of your business,” I said a tad irritated.“Fine just don’t be too loud, I want to sleep,” she said with smile.“We will do our best,” I said with a smirk, and that was the end of it.That night around. I love you. Do not be afraid of what I will think. I just want to help you feel better. As she talked she slowly snaked her hand down my stomach to the top of my panties. Slowly I let my legs relax enough for her to slide her hand between my legs. I looked her in the eyes as she began to rub my pussy though my panties. I moaned softly then bit my lip looking away to hide my embarrassment. Dont be ashamed. It is ok to feel good. I like hearing you enjoy this, she whispered as she reached down. My sister Sindy is a freshman.No matter how hard we tried, mom did not want to leave the house. She spent most of her time in the kitchen or out in the back yard by the pool. Finally this past January, she joined a gym and got herself a part time job at her friend Mary's travel agency. She didn't need to work, since father had left us pretty well off.Our lives change after mom took a trip to Costa Rica with Mary. Unbeknownst to us, Mary had been invited as guest of the Agua Caliente nudist.
