The text message alert on my phone was beeping relentlessly. In my groggy and half asleep state I couldn't figure out what one of my friends could possibly want on a Sunday morning. I flipped open my phone and realized it was a message from my mother. "Babe, since its Sunday the doctor is only in the office until 12. Its 9 now so please get dressed and be ready. I'll be home from the grocery store in twenty minutes." It read.
I sat up in my bed for a minute and then went to take a shower. As the water slowly ran over my back and down my ass, memories of yesterday came flooding back; the nurse, my mother, both of them bringing me to a shaking orgasm. The little drop of cum on my mom's knuckle. I must have lost track of time because the next thing I knew there was a knock on the bathroom door and my mom yelling, "Finish up in there, we've got to go!"
"Okay, Ma! Relax, I'm coming." I replied.
"I'll be in the car. Make sure you get the cup from the fridge before you come out." She said as I turned the water off and grabbed my towel.
I jumped into the passenger seat of the car, with my cup of cum in a little plastic baggie. As Mom drove to the doctor's office, I glanced over at her. She had on tight white sweat pants, sneakers, and a tank top and for some reason it seemed like her cleavage was extra deep but maybe it was all in my head. I have to admit, ever since Mom made me shoot such a huge load, I've been much more aware of her body.
We parked in front of the doctor's office and made our way inside. Mom was ahead of me and as much as I tried, I could not take my eyes off her ass cheeks swaying back and forth as she climbed the steps and opened the door to the office. As I sat in the waiting room I let Mom do all the talking and paper work for me at the front desk. The office was packed full of people and I realized that I was not so lucky with my place in line today. But, I figured that if the doctor closes at noon today, then that's the latest we'd be getting out of there.
I noticed the nurse pull my mom aside and start talking quietly in her ear. I watched my mom's face get redder and redder as the nurse talked and I thought that this couldn't be good. After what she already had to do to me yesterday, what could possibly make my mother blush?
"I'm sorry for not explaining it better Ma'am, but we needed two samples today: one from yesterday and one from today. It's no big deal, just let your son go into the bathroom right next door and make us another sample." The nurse whispered.
"But nurse, you don't understand! I had to do what you did to him at home last night in order to get his sample. He couldn't find that special spot inside by himself!" Mom squealed.
"Well ma'am, I'm extremely busy as you can see, so my suggestion is that you take your boy to our secondary bathroom downstairs in the basement to get the sample. I wouldn't want all these patients to see you and your grown boy go into the bathroom together and come out with a cup of his semen." The nurse replied and walked off to go about her business.
