After a long day of back and forth sexting, I told my girlfriend that I had a special scenario set up for her. I prepared a full gyno exam scenario... But with a twist. She would pick one syringe out of five "sperm samples (mixed lubricants that look accurate)" to be inseminated with. She read them, and picked the "23 year old male student" - which I inserted during her exam... Causing her to orgasm instantly. I continued the "exam" Then, I pulled out *my* selection, the syringe labeled "64 year old male, Gynecologist" I took it and showed it to her, with my fingers still inside, and asked, "Do you want the doctor's cum?" - She breathlessly moans, "Yes!" -So I inserted the syringe into her, and pressed the plunger, covering her cervix and filling her vagina. She moaned deeply as soon as she felt it inside her, which I couldn't resist...and we fucked until mutual orgasm.
