A guy is riding the bus when at a stop, the most beautiful woman he has ever seen gets on-and she's a nun. "Sister, you're the most beautiful woman I've ever seen and I must have sex with you," he says.
"I'm sorry but I've given my body to God," she replies and then leaves. The bus driver turns to the guy and says, "I know a way you can get her in the sack."
The bus driver tells the guy about the nun's daily 3PM confession. The bus driver tells the guy his plan and the guy leaves happy and excited. The next day at three the guy is in the booth dressed as a priest.
When the nun approaches in the darkness, he says, "Sister, God has told me I must have sex with you." She replies, "Well if God has said it, we must do it.
However, because of my strong commitment to God I will only take it up the ass." The guy figures this isn't a problem and proceeds to have the best sex ever.
After it is over he whips off his outfit and says, "Surprise, I'm the guy on the bus." With that the nun turns around and says, "Surprise, I'm the bus driver."
