btw. i keep getting told my begging is rlly hot, so. this is the basic formula i learned as a teenager:
1. request--the thing you're begging for. let me cum, don't spank me, get me pregnant, etc. be descriptive--usually, the more explicit, the better. make it sound appealing to your partner. refer to them by title (if applicable) in this step or the third step. not both.
2. promise--why they should do it. this can include descriptions of how whatever you're asking for will feel for them, how you'll react, or a promise for good behavior or quid pro quos. (in noncon scenes, this is also where you'd put a promise not to tell anyone/get the aggressor in trouble). this should be your longest section, and you CAN give more than one reason.
3. request--rephrase what you asked for in step 1. if step 1 was short, make this longer. if step 1 was long, make it shorter. this is the step where eye contact is most important.
in general, use a deferential, beseeching tone--you can choose how composed to keep it, but keep an undercurrent of "i'll die if you say no." (alternatively, you can lean into the humiliation of verbalizing your desires and speak soft and stuttery. but be warned, you'll run the risk of your dom making you repeat yourself louder.)
THIS IS JUST BASIC ESSAY FORMAT FUCK
