It's obvious that our resident jezebel put the moves on Baby Hands, and he was having none of it. In fact, there's a good chance he was never into it, and never anticipated that things would take a turn for the physical; as a few people have already noted, he sounded very young and was probably okay with having some weed and food purchased for him by the great big fat lady. She likely was just giggly and friendly and said they'd go back to her dump and stream on YT for a bit and have some food. What kid wouldn't enjoy that?
When she scooched up next to him on the shart sofa and tried making come-hither advances, he probably freaked the fuck out. And I mean in the classic sense: pushed her away, eyes bulging out of his head, stammering "NON NON NON MADAME, NON, MON DIEU, NON" and saying he wanted to go home right then and there. Absolute rejection, shock, disgust. She probably tried again--giggling--and assured him she just wanted to kiss, nothing more.
The sight and smell of those decaying cenobite chompers right up close, mere inches away, might have actually caused him to cry a little. He likely fended her off with one of the boxes behind them, waving it to and fro and batting her grabby fat paws out of the way, hid in the bathroom, texted a friend or two to inform them of his dilemma, and then went outside to wait on the front stoop for as long as it took for her to deposit him right the fuck back to the safety of his home. It's possible that he sat in the backseat for the whole ride, telling her "non, merci" to her offer of Starbucks and McD's on the way, probably texting on his phone the entire time, cackling out loud with pals about the greasy sphere of dirty lard who actually thought he might want to penetrate her yeast.
...that's my take. I'm sticking to it.
