Sam Johnson is drinking prosecco and having a lovely time splashing around in the hot tub, until her boyfriend comes in and tells her off. She cheekily asks "What are you going to do? Spank me?" So of course he does! He bends her over the side of the hot tub and uses his hand to spank her wet bottom until it's bright pink. He then picks up her hairbrush and uses it to spank her already sore bottom, making it very red indeed.
