Well, obviously if you can get in a position when you can touch his penis you can obviously work him to erection. If that isn't possible then talking to him dirty can get him there, but the quickest way is to let him touch you. If you could stand side by side with no one behind you then let him feel you up from behind, especially if you are wearing a skirt and he can reach your genitals from behind, let him play and he'll be hard in no time! But keep in mind, if you're in a group of people you'll have to take over the conversation because he won't be paying attention at all, and if you make him take part in the conversation he might loose his erection.
Through a group, you can give robux
no
By getting naked
There is really nothing to do. If he likes you, he likes you, and he will get an erection. Just grinding on him should be enough.
Get naked. Always works.
