Not On Monday

There's this guy who went to this camp for adults, so the owner is showing him around, and says, 'You're gonna love it here, especially the barrel behind the restrooms, when you feel the need, stick you're dick in the hole for a blowjob.'

'So the next day,the guy sees the owner, and says, 'This place is great, I'm going to use that barrel everyday.'

The owner says, 'Everyday except Mondays.'

'Why not on Mondays?'

The owner says, 'That's your day in the barrel.'
