Derek knocked on his Nana's door for the fourth time. He couldn't understand why she wasn't answering. He was sure she was home, so he wrapped on the door a fifth time.
The door opened, and Martha, Derek's Nana, asked quite abruptly what he wanted.
"I had an argument with Mom."
Martha seemed reluctant, but she told Derek to come in.
"Get yourself a drink, and tell me all about it, but don't take too long. I have things to do," Martha said in an agitated tone.
Derek couldn't believe his Nana was snappy with him when he had problems. There had to be a good reason; Derek had never seen his Nana in such a mood.
Concerned, Derek asked Martha what was wrong and if he could help.
"Derek," Martha barked. "Tell me about your silly argument with your mother, and then you can go home."
"Nana, I have never seen you like this. Tell me what is wrong."
"You want to know what the matter is? I will tell you. Your Poppa is away until late this evening, so that means I will be alone. It doesn't happen very often, so I have to make the most of it. This afternoon was going to be a pleasurable time for me."
"I don't understand, Nana," Derek interrupted.
"It is simple, Derek. Sex. Your Poppa is fucking useless now. I get pleasure from my toys. I was lubricating myself up when you inconsiderately disturbed me. Right now, I should have my black eight-inch vibrator doing its magic inside my cunt. Instead, I am here listening to you whining about some petty fucking argument with your mother."
Derek was stunned. He had never heard anything like it from his Nana.
"Do you want me to go, Nana? Derek asked timidly.
"Please yourself. I am going back to my bedroom," Martha said in a more subdued voice.
After Martha disappeared upstairs, Derek stood motionless for a few minutes, still in shock, and then he nervously followed Martha up the stairs. He stood outside Martha's bedroom, took a deep breath, and strode in.
Martha's panties were on the floor next to her skirt. Martha was on the bed, legs open, finishing lubricating her pussy.
Derek watched as Martha's finger slipped back and forth inside her pussy.
Without looking up, Martha said, "Would you mind putting the lube on the drawers, please."
