Just north of Louisville KY is a ABS with gloryholes I got best head one time I wanted to see what the girl looked like that could suck that good. I stepped out of the booth and hung out after another 5 or 6 guy's went in and came out the other door opened and my daughter and her boyfriend stepped out we locked eyes for a second then they left
That first knob job was something! The last guy couldn't get off - that happens at the gloryhole, though. Most likely he'd already cum before this girl. Some guys spend all day jacking there, and have nothing left when a good knob job opportunity "arises." She did a good job!
