Ass behind the glass

I've cast a spell in front of you. It's created a glass wall between you and I. You can SEE what I'm doing - but you can't touch, kiss or even smell. So. I use this to taunt you with my beautiful big ass. I push it right against this glass barrier and no matter how hard you try - you just can't get close enough. Lots of taunting and teasing, but you just can't get what you want. Hahaha.
