Cold plunge, then passionate sex

Three friends (Emily Pink, Francis X, and Renato) scurry into the house after having taken a cold plunge outside, warming themselves up with towels. As they chat, it's revealed that this is their first time taking a cold plunge. Although they really liked the plunge, now they're chilly! As they all individually towel off, Emily looks at the guys and gets a naughty idea. She suggests a DIFFERENT way of warming back up... using their body heat, of course!
