Lesballoon
A lesbian who likes to be inflated like a balloon. The Lesballoon is the "inflatee" in the situation, and if they have someone else inflating them (the "inflator") they prefer it to be another female, bonus points if the female inflating them is a crush/girlfriend/wife.
I watched as my girlfriend inflated full of helium, like a balloon! I thought it was just her ass that was going to inflate, but her belly and breasts did too! Now she's not even recognizable as human! She's a big round perfect sphere! She's a lesballoon!
