Ageplay girls like me love a nasty perv doctor. My grandbrat was a bit sick so I took her in. He had her strip down to just her panties. The doctor said how he couldn’t get a good read of her temperature so he would have to check her through her bum. Kids get nervous and cry when parents are around, so he asked me to wait behind the curtain. I snuck a peek from behind the curtain and he had pulled his cock out. He lubed his cock up and covered her mouth, telling her to hold her breath for the thermometer. I watched as he shoved his hard grown man doctor cock inside her butthole. I watched as he fucked her slow and deep. He then sped up and finally tensed up and pulled out and I saw him cum on her bum. After cleaning her up he gave her a lollipop and opened the curtain. He let me know what I had to do to get her well and how he needed to see her again the following week. From what I saw, I knew I would be making money from the doctor making a house call.
