.. "What do you want?" "How many days have I been here?" The doctor replied "Don't worry, you just have here around 3 days I think and now you might b...e wondering how you ended up here" said the doctor with a mysterious voice"Well, the government gives me a new specimen to experiment on every month and it turns out that you were chosen. Congratulations!" said the doctor with a humorous voiceDavid couldn't believe what he was hearing, what was this man going to do to him? he wondered. She was sucking my penis like the greatest piece of candy in the world, an innate reaction to just live through the orgasmic high she was having. Her tongue rolled around my shaft.I immediately began spasming and inseminating her mouth. My hot cum fountained into her; down her throat, over her tongue, into the roof. She began choking and coughing. I remained suckling her dripping girl organ.I squirted line after line of sperm into her mouth. She eventually stopped coughing and began. I'm in love with my brother, and I can't stop wanting to fuck him. Put his cock in between my legs." Cyndi panted rhythmically as she spoke.She slid her hand down on my cock, slowly caressing it with her soapy fingers. Her breathing quickened as she ran her thumb over the head and tightened her fingers around the shaft. I grunted in approval as my sister began to jerk up and down on my cock. She pressed her lips against mine and started french- kissing me deeply, nibbling at my lips and tongue. I was also attractively dressed and she couldn’t hide her excitement on seeing me. We both hugged each other on the airport and her boobs were touching my chest now. I could feel them for the very first time.Then we took a cab and I asked her where to go. She said that we can go over to her place instead of going to park. Then I said that your family members wont have a problem with me. Then she said that only her mother is at home and she doesn’t interfere much with her friends so we can go.
