Falling asleep with something in your anus

[virtualflowe]

I love masturbating with a dildo or a ben-wa ball in my anus but can't be bothered going to the toilet to take it out after cumming.

All I want to do after cumming is wiping up the cum and falling asleep.

So my question, dear reader, is whether there is any adverse effect of sleeping with something in your anus? Have you dont it before?
