Honey, there’s nothing to be embarrassed about. Checking your testicles is part of the exam. We are going to the doctor, end of story. Mom has an idea, pull your pants down and show me your testicles so you won’t feel so awkward. I’ll even make pretend to be the doctor by touching and cupping them. You’ll feel another set of hands on them besides your own. I’m very aware you touch your penis and testicles on a regular basis.
My hands are nice and warm, see? Your penis is getting hard which is normal. Wow sweetie, your testicles are so BIG and FULL of semen. You didn’t ejaculate today yet? My they are MASSIVE. Mmmm this is such a proud Mom moment. I love having a son with BIG BALLS. And a pretty nice dick too, of course. I’ve noticed huge cum stains on your bedsheets. You should cum at least once before your doctor’s appointment. I’ll help you out this time. Feel me stroke your naughty, horny cock while cupping your cum-filled testicles until you give me that ooey-gooey sticky surprise.
