i fear if you told pierrot and harlequin they can do whatever they want to you, you would end up more intact with harlequin instead of pierrot. now when i say "whatever they want" it means they can go all out and don't need to worry a thing about our precious visitor (you!)
imagine how ecstatic they would be. harlequin's definitely gonna be more smug about it, though.
think about it. poor guy pierrot been holding himself back since day 1, of course he's gonna get too excited the moment you let him do as he wish without restraint. not only the bed is broken, YOU might be broken too.
it doesn't mean you're coming outta harlequin's tent unscathed tho. he's all for marking, be it with his mouth or the suckers on his tentacles - YOU WILL have his brand, and YOU WILL wear it with pride.
