For quite a while the preferred time for having sex was a weekend morning. That was also the time when I would have my weekly enema. The decision we needed to make was which one came first.
While wifey wasn't the least bit interested in erotic enemas, she didn't mind that I indulged. About half the time she would opt for after my enema session since it allowed her about an hour of exrta sleep. I also liked that arrangement as the enema would get me sexed up and the resulting orgasm during sex would be wonderful.
I would get out of bed, prepare my enema, place towels on my side of the bed, hang the full bag from the hook by the window, lube up and insert the nozzle or rectal tube. Wifey would massage my abdomen while the warm solution flowed. She always ignored my penis during this time, even if I became rock hard. After expelling and cleaning the enema equipment I'd join her in bed for a most satisfying bout of lovemaking.
When we had sex first I'd be left to my own devices while she got up and prepared for the day. More often than not, that post sex enema resulted in another nice manually induced orgasm.
Occasionally our child, who normally was a sound sleeper would walk in on us. Usually that wasn't an issue as enema activity was commonplace in our home. Only once did I have to get creative in concealing my erection while in the middle of an enema. Family nudity was casual, but we were careful when we were engaged in sexual activity. The close call was amusing at the time.
