lewd, multi, unconventional penetration
Something occurred to me the other day. If you have multiple genitalia, but don't have the entire reproductive system duplicated, then at some point they must all connect internally. Therefore if something flexible enough were to penetrate one of your genitals it could then loop around and exit another one.
lewd, multi, unconventional penetration
@Felthry I think that could bring a whole new meaning to being knotted.
