A walking erection

Bro, I saw you in the grocery store. You were hard. Like, really hard. I almost asked if you wanted a second opinion.

My mom told me I was walking around the house like a horny goat. I said, 'You're just jealous.'

He was walking into the office with a smile. I said, 'You look like you just got a raise. Or a hard-on.' He said, 'It's both.'

I asked him why he didn’t finish his math homework. He said, 'I was too busy thinking about my cock.'

He walked into class and said, 'Today’s lesson is about hard-ons and math. Pick one.'

His teacher said, 'You’re not paying attention.' He said, 'I’m paying attention to my cock.'
