Giving JOI for son while modeling with tiny panties

Mommy is getting ready for a photo shoot with tiny panties. You walk in while picking out which sexy pairs to bring. You convince me to let you stay. I notice a huge bulge in your pants as I am disrobing and trying on panties. I ask you what you fantasize about and give you JOI. I encourage you to stay and even bring out my vibrator so we can cum together 🙂 ENJOY!
