Submissive shy jojo who doesn't talk much about what he needs, so you should force him (not in a harsh way) to talk about what he wants through his whines and whimpers while he's dry humping your thigh
aaa anon its similar to what i wrote for my first jo post!! he's so cute i swear i love him so much :(( i hope this is what you wanted anon, if not please let me know 🥹🙏🏻
anyway as much as jo is shy about verbalising what he wants, you have a few ways to get him to blurt them out.
one, edging. the more desperate jo becomes, the less shy he gets. he would almost immediately start begging for what he wants with those oh so sweet puppy eyes filled with unshed tears :( and of course who is to deny our sweet little boy like that right? edging him while dry humping your thigh would rile him up so much he'd start rutting against your thigh like a puppy in heat, rambling over and over again while hiding his face in your neck.
two, choking. something about jo screams freak (positive) and choking would be a guilty pleasure of his. he'd be dry humping your thigh and getting used to the friction he's receiving when you slowly drag your hand up his stomach, chest and then to his neck. you leave your grip loose on his neck, watching jo's expression closely, furrowed brows and eyes squeezed shut to widened eyes and a deep blush colouring his face. he'd test his luck by placing his hand over yours to tighten your grip on his neck. you slap his thigh and move his hand away, reminding him that he wouldn't get what he wants if he doesn't tell you. a loud whimper from him would signify that he's about to start begging, a proud smirk plastered on your face.
