I have done this too often to count. Sometimes with her full, sometimes with me holding. Have never used any form of plug. The best times are when we both are holding. I play frequently with a friend who is an RN, and also earns a little on the side as an enema nurse. We have been friends since college, when we were dating and she asked me if she could practice giving me enemas. She knew about my chilhood enemas, so I seemed her logical choice. She obviously enjoyed doing it, and one weekend, surprised me with, "I think it would be good to know how this feels. How about you give me some." We were intimate, and the remains of 2 qts of soapy water were still in me. Naturally, I agreed. She quickly stripped out of her scrubs, and we mixed up 2 qts of hot soapsuds. She giggled a lot, and practically flew onto her table and into the stirrups. I was suspicious when she took the SSE quickly, with obvious gusto. "You fibbed; this is NOT your first enema! You took it too easily!", I tried to sound harsh, but couldn't hide my feelings. She giggled, "Busted! We did some in lab, and I had to pretend not to like them; but my lab partner and I talked later, and she got aroused, too. BUT, you are the only guy who has ever given me one!" We were sex partners, but never lovers. I married; she became a nurse practitioner, and set up the enema room in her condo. We played frequently, on the sly, and to my knowledge, I am the only freebie she sees. She gets very much more aroused if we have sex while my enema is in me, and doing her when she is full does the same for us both. One day, instead of her enema room, she led me to her bedroom. I was already naked and holding a bisacodyl suppository. She stripped and peeled another supp, then climbed on her bed in knee/chest. "Give me this, and let's mess around til they work, then I have a surprise..." I did, and we played with each other, the arousal heightening as our suppositories worked, causing our bowels to churn. Finally, we agreed that we would shit if we didn't quit and go. I used the bathroom for her exam room, and she, her bedroom bath. We could talk, and hear each other's bowels as we farted and blew poop into the toilets. After several minutes, we were finished, wiped, and headed back to her bed. She said she thought we would get one more BM from the supps, so we got back to some hard foreplay. Her slit was dripping, and her arioles were turgid, like little cones on her breasts. Her nipples were hard as rock. My cock was definitely ready! True to her training, we had to go again in about 10 minutes. This time, when I got back to the bedroom, she had IV stands on either side of her bed, with 4 qt open top bags full to the brim, soapsuds spilling over the top. "Surprise! We're going to fuck with enemas in us! Meet me in the middle and let's install each other's nozzle!" I required no coaxing, and soon we each were sporting green barium nozzles and red hoses sprouting from our asses! The bags were hung low for a slow fill, and we immediately opened our clamps. She rolled onto her back, and I mounted her. The nozzle moving in my ass as I stroked her made holding back my sperm very hard, but I managed through her third orgasm. I was really having a hard time holding back, but we both noticed that our enemas...all 4 qts...seemed to "disappear" from our minds as we fucked. Finally, she said, "I cannot handle one more "O", go ahead!" I worried, "We'll lose the water as we finish!" "It's OK, there's a rubber sheet on the bed!" I redoubled my efforts, and she got one last, screaming, shaking orgasm as I douched her with my load. We both became very aware of the soap water in us, and she said, "Go ahead...do what you want to do, it's OK!" As if to add credibillity, she let go with a huge, gassy, messy release, and mine joined hers. The rubber sheet worked, and we grabbed towels to "diaper" us for the rush to the toilets. An hour later, we were showering and getting horny again as we scrubbed each other. We had sex one more time, but were too exhausted to really enjoy it to the fullest. I dressed and headed home. We still meet for enema sex, and sometimes do it with full tummies, though it is a pain getting ready and cleaning up. My wife has a long weekend with her sorority coming up next month...
