Stepmom joins in on my self-pleasure session and assists me

I've been harboring a secret from my girlfriend for quite some time now. Every time she steps out, I indulge in self-pleasure while using her vibrator. However, things took an unexpected turn when my stepmom decided to join in on the action. She's a fan of the kinkiest stuff and she wasted no time in getting involved. She swiftly stripped me down, exposing my throbbing member, and began to wank me with her ample bosom. It was a sight to behold as my stepmom's large breasts worked their magic on me. The scene took a turn for the dirty as she licked my balls, leaving me in a state of euphoria. Just as things were reaching a climax, my girlfriend walked in, catching us in the act. The sight of her man covered in cum was a sight to behold. It's a tantalizing display of cuckoldry and a testament to the steamy encounters that unfolded in the comfort of our home.
