hey! i'm young and new here, but i'm not really new to getting dominated and humiliated

i've been wrestling with my friend for quite a while, but it usually ends up with me cumming helplessly in my briefs, sometimes twice in a row

i have really sensitive nipples, all it takes is one pinch and i'm moaning and melting with a boner. it doesn't help that my briefs are really thin and skimpy, either 🥹
