Reminds me of the time
when me and the Mrs tried out one of those Durex vibrating rings. All went swimmingly and felt quite good (for me at least) until I finished, pulled out and it was nowhere to be seen. It was only when we noticed a slight buzzing sound coming from her lady bits that we realised I had somehow rammed it way up inside her.

Took her ages to get it out. Annoyingly, she refuses to use one anymore.
