I had this idea I came up with recently. You take an enlarged and adapted version of a prosthetic finger and fit it to a small motor. If you dont know what I mean there's a prosthetic finger design out there with cables inside that contract and pull the finger closed when the wrist is brought down. I'm thinking like a dildo with this inside so that you can get the feeling of the penis wiggling inside of you. Idk which ones but I know there are some animals that have a tentacle like control over their penis and I think that would feel wonderful.
