Completely agree. Just watching him pleasure himself rubbing against the soft fabric until he succumbs to his inevitable orgasm. Good thing about undies pleasuring is. You can enjoy it absolutely anywhere.
Fascinating how You pamper your dick so "nice" in your underpants and donate your warm load of "seed" in it, nothing "tasty" than this and asking for "more and more?", mmm ... .. .
