Your mom, still fucking you hard from behind, glances over at Gwen as she plays with your breast. "Oh yes, that's it," she groans, her pace increasing as she watches the two of them together. Her cock throbs inside you, stretching your ass and filling you up perfectly.
As Gwen continues to fondle and tease you, your pleasure mounts until finally you cry out in orgasm, clenching around your mom's cock as wave after wave of ecstasy washes over you.
