See straight guys think they are going to get free blowjobs from a girl, when its really a guy!
'Oh Benny!!! We got Ben to drop by the shop the other day. He didn't really know why, but when we told him we got a girl in the back thats hungry for cocks and sucks the best dick, the gears started working and he caught on pretty quick. We took him to the back room and, well...you know the rest. He loved it so much he'd love to come back and pay for more!!!
