I knew what awaited me behind my Master's office door!I knocked and he called me in. 'Lock the door behind you Samantha.' 'Yes Sir' I responded. I wal...ed over to his desk and he took my hand and pulled me towards him and guided me down so that I sat on his knee. He pulled me close and I could feel him hard against me as his hands glided over my body. My breath became short and quick, his hands on me felt so arousing. 'Now......assume the position Samantha', he asked of me. I stood up and bent. But the imagination of going to her and burying myself into her arms made me think that I should do it and it’s no big deal. I slowly opened my house door and quietly went out.I didn’t have a car then. I pulled my two-wheeler out of the gate, few yards outside my house, started it, and started my journey. It took me 10 minutes to reach the lane behind her house. I was nervous as hell.I moved across the empty plot, apprehensive if I was being watched by anyone or what if someone sees and reports. She seldom has an orgasm with me inside her, and I’m sure that contributes to her interest in other males. What led to bringing other men into our bedroom, or her hotel room? I had no idea this could happen, as we hadn’t really discussed it although she’d hinted at having some very satisfying sex with some of her dates and I wondered if I’d be up to the task. She laid it all out one night, and secured total buy-in from me. A sexy woman is one thing, but an intelligent and sexy woman is the. ..fill my fuckin' mouth with your hot load ...give it to me baby, I wanna' drink from your cock ...give your little cum slut some cream ...I need it baby ...I wanna' swallow your load ...pump your hot cum into my slutty mouth ...let me taste it baby ...feed it to me baby ...shoot that hot fuckin' cum for me!"My knees were shaking and I couldn't resist any longer as the intensity of my orgasm seared through my body. I briefly saw Cathy open her mouth for me as my eyes closed and I grabbed her.
