Carla likes her anal with a little B&D. Her favorite position for about our first twenty years was lying face down, with my knees straddling her hips, supporting my upper body on my left forearm, and giving her a reach around with my right hand. After she climaxed, I'd pull my hand away, support my torso on both hands in a knees down push-up position, and after another minute or two, ejaculate in her rectum
Shortly after we went anal only, we discussed how submissive it made her feel to be sodomized almost every day. Our next time, after her orgasm, I supported myself on my knees and hands as usual for about a minute. Then I placed them around her wrists (my hands are very large and strong) and supported my weight on my knuckles. She blurted out, "It feels like you're raping me." I loosened my grip, and she said, "Don't stop. I like it." The she began to thrust her bottom upwards, as if trying to buck me off, but only making me go deeper.
For the next 20 or so years, our alternate rituals were the same. After Carla got off, I'd ask her politely, "Do you want me to rape you?" She'd either say "Yes," or "This time I want to kneel" or "This time, I want to be on my back." Over the years, her enthusiasm for pretend-rape grew The more pleasure she got out of it, the more I did.
Big turn-off to some of you, especially women. But as flower children of my generation used to say, "Different strokes for different folks."
