Slutty sister in law Callie decides that one brother isn't enough and she wants both. Calling her brother in law round under false pretences, she soon makes her move - although it doesn't work out quite how she expected, and she soon finds herself over his lap getting a spanking on her bare bottom. Her angry step brother spanks naughty Callie until her bottom is very sore and very red, then leaves her to think about what she's done. Surely she won't ever try that again - will she?...
