London River seems like such an affectionate Mistress (or Daddy, as she prefers to be called). She greets her slave with a long kiss, and hardly ever raises her voice. Instead, she lets her actions convey the message, as she takes well known pain slut Marcelo to the edge of his limits. Daddy London gets Marcelo warmed up by having him such her enormous strap-on; when it`s nice and lubed up, it goes deep into her slave` gaping ass. Then it` time for his dick to get some attention-London squeezes his balls and bites in them hard. Then she attaches nipple clamps to Marcelo`s already sore balls. And she`s just getting warmed up!
