For how good it is, it was worth the investment.
Hismith Premium Sex Machine,Wire-Controlled Love Machine with Dildo https://www.amazon.com/dp/B01N6340A8/ref=cm_sw_r_cp_api_glt_fabc_3J3CQR0RJY2VGVSMSTP6 This is a newer version of the machine I got if you’re interested. If you want to see it in use first, I have some videos on my profile of me using it.
What you need is a basic enema bulb. They're available at some pharmacies, including CVS if you live in the United States - I'm sure they're also fairly easy to find in other parts of the world, but I don't know specifics. Anyway, it's basically a rubber bulb that you fill with water, and then a nozzle that attaches that you can use to squeeze the water in. It's good for a quick cleaning, and is easy to keep hidden since its small. Something like this. That being said, since you're not experienced with enemas, definitely make sure you push out *all* the water before you start playing! Sometimes water will get stuck up behind your colon which will make it feel like you're empty, only to get let out later once you're playing! It can be very messy. I usually just stick a few fingers up there as deep as I can go while I'm still on the toilet to double check. You'll get used to it after doing it a few times.
Anyway, I definitely recommend getting yourself nice and clean before play sessions - feces can cause friction and discomfort, plus then you won't have to worry as much about cleaning poop off your toys, hands, and other surfaces.
