I do have a badge from pregnancy with DS as I needed to commute into London. But no clue where that's gone... it's a local town bus service, I don't think it would be appreciated or understood by many who use the buses here.
As luck would have it though, I nabbed a seat easy enough!
Nausea is massive on here though, the smells!!! Urgh!
Okay, so we use it in foreplay and occasionally throughout sex too (DH would just line a bit up on his cock)
