I'd love to see one where either a mom wraps her son in blankets puts him in a sleeping bag, maybe as a time out or something, or a girlfriend does the same to her BF. All in good fun, of course. No sexual activity. I'm not big on that, personally.
Sleeping bags just seem like a fun way to get put out of commission, and snuggled where the captive can't do anything about it! I wish I'd thought of it while I was younger...
I know this is the adult section, but this isn't getting any traction under the "stories for everyone" section.
