They leave you alone to recuperate

After they've collected their clothes and cleaned themselves up, Missy and Maria wish you a happy birthday and head back out to continue their survey. Just before she leaves, though, Missy steps close to whisper. "I'm going to be playing with my vibrator and thinking about you when I get home. Remember that the next time your cock is in another woman's mouth."

It's a pleasant image, and it lingers in your head when you stagger back into your bedroom and collapse. You've had a busy morning, and a brief nap is in order.

It feels like you've just barely closed your eyes when the doorbell rings again.
