Invisible Intrusion: Girlfriend Orgasms Uncontrollably Right in Front of Me

My girlfriend's body is unusually sensitive today. Using an invisible toy, I make her climax in front of me—her pussy twitches and squirts as she tries to hold back. Sliding into her bare under the short skirt, I pound her until she moans uncontrollably, her big breasts bouncing while she squeezes me tight. The mysterious pleasure turns her into a total slut; I fill her with a deep creampie, leaving her completely satisfied and overflowing.
