My phone was ringing as I stepped out of the shower, I could see it was my daughter Sam, calling me.
"Hey darling, howzit?" I asked.
"Hello dad, I'm all good thanks. What you doing?" she replied.
"Just got out of the shower young lady."
"Oh nice, you know I love to see you naked!"
My daughter was a widowed woman of 40, with an 19-year-old daughter, Maddie. They lived on the other side of town to me, but we got together as a family quite often. She had lost her husband in Desert Storm several years back.
I was almost 60, living on my own, keeping myself fit and trim in the gym or on my bike, and yes, my daughter and I had developed a more intimate relationship after the death of her husband and my messy divorce.
"Naughty girl," I told Sam. "I hope no one's around to hear you talk about your dad like that?"
"No dad, Maddie is out but I do need to ask you something, something about Maddie."
"What's up with Mads?"
"She's gotten into the wrong crowd at college and is rapidly going downhill regarding respect and her attitude towards me and her teachers. I was called into her college yesterday and given the details, it's not good."
"Did you not know?" I asked.
"I thought it was teenage rebellion, she was just acting out but according to the college it's far worse. Smoking, maybe drinking and drugs, and her grades are way down."
"What about boys and sex, is that the distraction?"
"I'm sure she interested, but I'm pretty sure she's still a virgin. We have spoken about contraception but for now it's all done on trust."
"So, what do you want me to do Sam?"
"I want her to watch you punish me, show her what happens to girls that don't behave. Can you do that?"
"Why don't you punish her yourself, ground her or something?"
"No, that won't work. I want her to understand that a good hiding awaits her if she doesn't improve and that you will be dishing it out!"
"Me, you would want me to spank my own granddaughter!"
"Yes daddy, if needed. You spanked me when I got out of line and I'm partly to blame for her attitude, so I need you to beat me again. In front of her!"
I had to get my head around this so my daughter, who I was having an incestuous relationship with wanted me to thrash her in front of her own daughter, my granddaughter. It was a lot to take in for a minute.
"If I agree what are your limits Sam?" I asked.
"None, you punish me as you see fit and Maddie will watch me take it and I hope, will change her attitude so she doesn't get the same. Please dad?"
The please dad was in her best, wrap you around my finger voice, we both knew I was in.
"This Saturday afternoon then, when you get back from shopping." I told her.
"Yes daddy."
So, this was how I came to be in my daughter's bedroom, with my granddaughter listening to Sam explain to her about her college report and what the consequences would be if she didn't improve.
"Have you gone mad mum?" Maddie shouted. "You're going to make me watch grandad punish you for my performance in the hope that I'll improve so I don't get the same thing. I'm nineteen for christ sakes, I can't be spanked!"
"If you want to remain under my roof and keep getting my money, you'll do as you're told my girl! I've been too easy on you but I'm prepared to accept my punishment and change, you will do the same!"
The two women glared at one another, but it was Sam's authority that won the day and I watched Maddie's shoulders drop as she accepted her mum's ruling. She knew she was beat.
"Ok mum, I'll do as I'm told and stay here and watch if that's what you want."
"It is Maddie, thank you."
Sam turned to me. "Well that's sorted out, over to you dad. How do you want me?"
I spun the dresser chair into the middle of the room and sat down.
"Come over here Sam," I told my daughter.
She obediently came and stood to the side of me.
"You know why you are going to be punished?" I asked.
"Yes, because I'm not being fair to my child by being too lax and because I asked you to."
I patted my lap and Sam lowered herself across my thighs. She shuffled a little getting her head down low and ensuring her ass was at a good height for me.
I took the hem of her skirt and threw it over her back revealing her bare ass with a small, red thong, nestled between her butt cheeks.
"I'm going to pull down your panties now Sam," I said.
Sam said nothing but I heard a small gasp from Maddie as she heard me speak to her mum.
I took hold of the waistband of Sam's panties and pulled them downwards bringing her perfect and tender ass cheeks out from the confines of her flimsy red thong. I slid them down her thighs and flicked them from her ankles, they pooled on the floor, now my daughter's entire bottom was completely exposed to me and my granddaughter.
I looked over at Maddie and said to her. "Come pick up your mum's panties please Maddie."
She looked at me for a second or two, deciding what to do then stepped forward and bent down and picked up the thong. She held the tiny garment in her hand clearly not sure what to do with them.
"Are they wet Maddie?" I asked her.
"What?" she replied.
"Are you mum's panties wet I said, on the crotch. Feel the fabric and tell me has your mum soaked her underwear because she is about to be spanked?"
My throat caught slightly as I watched Maddie unfold her mum's panties looking for any dampness. She held the crotch up for me to see and the darker stain there revealed my daughter had indeed soaked her thong.
"Yes grandad, mummies panties are very wet," Maddie said.
"Thank you darling, and what do they smell like?" I said, wondering how far I could push Maddie.
"Smell like?" she said, "I can't sniff my mum's panties, that's disgusting grandad!" she retorted.
"Maddie, do as grandad tells you, don't make it worse for me," Sam told her daughter in a firm and no-nonsense voice.
A brief eye contact between them clearly had the desired effect on Maddie and she drew the soaked thong to her face and sniffed the crotch.
