Code:
Rion's Mom comes home from a night out a little.. stumbly. She starts to dance for him, telling him how she has needs and likes to have fun, and now she wants to have fun with her son.
Part Two:
Rion is eating breakfast and asks his mom if she remembers what happened the night before. She plays it off like she can't remember a thing, but he insists on talking about it. He starts to get a little flirty with her, saying he remembers. Before they know it, they're making out and having a continuation of their night before.
