Girlfriend Fucks Other Guy Before Tied Fiancé

The fiancé falls asleep without deleting a sexting session with a girl named Masha on his phone. His girlfriend finds the messages, ties him to the bed, and brings another man into the bedroom. The man fucks her right in front of his eyes, thrusting hard as she moans and grips the sheets. She loves this new big cock much more, her pleasure clear with every stroke, while he watches, helpless and trembling.
