The woman directly in front of me, whose face is almost completely hidden, is pretty hot. I'm 54 and she's one of two people in the choir younger than me. She's in her late 30's, and has the most amazing ass. Standing behind her, it's tempting to just stare at that ass the entire time, and since everyone else is looking down, I wouldn't even look out of place doing so. But I can't. Singing in the choir -- while technically not "performing" so much as "serving" -- is still musical performance to me. I'm gonna look up and out, make eye contact with people, etc.
The woman in the red blouse in front of me and to my left, is alright, too. Not a great picture there.
