I'd written a couple of other notes on this thread below but another aspect just occurred to me. My switch ex Dommes, wives or GFs, all knew intimately all about my kinks of rubber, sneakers, anal, enemas, bondage and D/s and we did them all together frequently sometimes all at once. But another aspect or secret of mine, rather than a kink, played into our kink playing time too. I really enjoyed and encouraged them/her to give me very intense and embarrassing enemas, as the added humiliation really added to my arousal. But equally so, that only worked because I knew she was completely honest and private and would never tell anyone else we knew about the embarrassing things she'd do to me during enemas and sex. In fact, we'd sometimes joke about it during enema scenes where she wanted to do something even more embarrassing or severe to me, like give me five quarts or more or tell me to hold it overnight or do demanding exercises. So she might tell me, "well, I really think you'd better take that five quarts of soap and let me watch you struggle holding it for an hour or I might have to to start videoing this and showing your friends." Which would make me about instantly compliant and let her do just about anything she wanted to me............... Truly exciting, submissive and erotic.
Actually, one of her best "humiliations" was dressing me in complete head to toe latex, gag or gas mask and heavy rubber sneakers, and filling me usually with two sequential enemas without letting me release the first one so I'd have about 3-4 quarts in me. After making me sweat under the rubber, which fortunately I loved, she'd order me to climb up on her in my sweaty rubber and full belly and give her PIV sex. Just crawling across the bed in hot rubber and a distended belly was enough, but feeling and listening to my belly contents slosh around while thrusting was really something unique. If I didn't orgasm soon enough, she tell me that she just loved pumping water into me and every 5 or 10 minutes with no orgasm would get me another dose of enema.
