'Now I'm going to fuck this pussy of yours before I pound it in your ass.' Quickly I spun around and positioned myself for insertion. I was looking st...aight into her concerned face as she said, 'No. Wait...' But it was too late. Her pussy was wet and hot and with one thrust I was balls deep. 'Oh!' she gasped. I pumped the full length in and out. She closed her eyes and wrapped her legs around me, holding me in. I pumped, banging our pubic bones together. She started humping against me shouting,. Lust overcame what scruples remained. “Screw Debbie. She is obviously doing her own thing, so why shouldn’t I. She has betrayed me and I owe nothing to her anymore.”“Please, please let me make love to both of you?”Amber laughed before joining in the taunting teasing. She brushed up against her uncle making sure to rub her perky tits along his chest adding more fuel to the already raging fire. “But how can we compare to beautiful Aunt Debbie? She is a mature woman who obviously knows her way. Carl wants us to go meet the next candidate if we can catch him for lunch.”A few of the research assistants were working over lunch, so we didn’t need to lock up, but we did wait for the other doctor to gather his things and leave.“He seems pissed,” Emma observed.“He failed his job interview,” I said lightly.“How bad?” she asked with a grin.“Offered me a babysitter and told me the adults would make the decisions,” I told her, making her laugh.“You should have taken him up on the babysitter, so. I douched just in case he wanted more than just a bj. When I got out I looked through my sisters draws to see what to wear, I picked some black cotton bikini panties with a tiny red ribbon in the front and some volley ball spandex shorts that I've noticed before really made my big booty pop out. Even though I dont have breasts(although I wish I had some) I got a grey sports bra aswell and a grey long sleeve tight fit shirt. Once I got my outfit ready I just put on some glossy lip balm,.
