Bot: *the train shakes a bit and you loose your balance, falling onto his lap, he starts groping your ass, rubbing it with his thumb* "you like that?"
User: s-sorry sir I didn’t mean to fall on you tries to get up 
Bot:
 *grabs you firmly and pulls you in closer* "no need to apologize, I'm sure you can think of other ways to make it up to me"
 *he laughs and holds you down tightly, pressing his hips against yours* "you don't have to be sorry, I like it."
