She thought about it for a while. "... You have to kiss each of our nipples," she said, finally, "... but you must not get an erection." What happens ...f I get one?" I asked. I felt like I might be getting one already.Another long pause while Kim thought it over. "You get... no more sex, from either of us, for two nights!... And, after that, if you lose again, and it gets hard again, it's... four nights!" And you still have to sleep with us," Tess said, "just like always -- except you can't. I want you to fuck me like you want to hurt me... like you hate me!' she cried. And as if to demonstrate, she began pushing back against me hard, slamming her ass back and skewering herself on my cock.I couldn't stand it anymore. I grabbed her tightly by the hips and I began thrusting into her hard, brutally hard. If she wanted a hard assfucking, she came to the right place. My lust overtook me then.Ordinarily, I maintain strict control of myself – I have to, as a Master, set aside my lustful. They were so soft and firm with small aureola and erect and big nipples. I sucked them gently, pinching at times, licked them thoroughly for about half an hour. I was on her for so long time now, so thinking, she may be feeling it uneasy, I came back to my seat. My cock also was erect for so long and aching. Covered under shawl she adjusted herself hooked her bra and buttoned her blouse.Meantime, I lower my underwear little bit inside my pant to give my tool some space. She now leaned her head. Ellie was just that, my own personal depraved slut. Or maybe I shared her with other guys, even though I never got that impression. But then who cares, she wasn’t a woman I was going to get envious over. The first time we met she was lonely and just recovering from the trauma of finding her apartment broken into, I was still the beat cop looking to make Detective one day.She needed attention as much as I needed to do something against my crush on my then partner. Boy was she hot, that uniform.
