I just read this thread today for the first time and have really enjoyed it. The first quick comment I'll make is to Sophia's post #20 from 4/18/2016. I'd love to be an invisible spectator when you are giving your husband your huge enemas and then making him hold the water while you sit on him to make him come. I loved the phrase about nature putting him to sleep post-orgasm (oh, yes, this is so true!) while he's struggling to get up to the commode without losing any water. Since I'm divorced and single, I can only hope to find a badass lady like you to love and play with! Glad you both enjoy your enema games - I'd love it too. Does he ever beg for you to get off of him before he orgasms, to go and empty? Are you playing these times as Domme and sub, or more like equals making each other do challenging erotic activities?
Expulsion Orgasms:
The other experiences I thought of when seeing this thread were those when I've played solo but mixing several of my kinks. I've lost count over the years of how many times I've done this. I'll dress in almost complete rubber enclosure, wearing either a 2-piece neoprene rubber wetsuit plus hood, thin rubber gloves and sneakers, or a thin black latex catsuit plus gloves, hood, and sneakers, all in the bathroom. Then I'll lie on the soft bathroom rug(s) and insert an enema nozzle after pulling my wetsuit pants down or unzipping the catsuit a little. Now doing it this way, I've orgasmed at various times during all parts of my enema, from filling to expulsion, which are all intense and wonderful. In particular, what I'm reminded of are the times I come during the emptying. Now I'm multi-kinking here, using rubber, sneakers (more rubber), and enemas, but I accidentally found that I get the most intense and spectacular orgasms when I'm sitting on the commode and the orgasm comes when I'm pushing out a lot of water. There's something about the combination of the simultaneous muscular orgasm contractions and rectal contractions while emptying that just seems to intensify the orgasm. It might be that I can just enjoy all the different contractions occuring without having to be careful to not leak anywhere.
Now most of those were in my relative youth, probably late 20's to late 30's (64+ now) but I'm thinking I might try to do the expulsion+orgasm intentionally again, as I have ED and enemas already help to get erect and orgasm. Saving the orgasm until expelling the enema might even be more helpful to me than at other times like filling or holding. Sounds like something I might be able to resurrect with great pleasure(s).
