On that amazing day when Consuela fucked herself with my cock for the very first time while my mother watched and cheered us on, I had noticed in passing that the lines of age were not as pronounced as I had thought them before, and that the sag in her breasts was not so obvious as I remembered. At the time I had passed this off as the product of a faulty memory, but afterwards I wondered if perhaps there was more to it.
My mother took to popping in daily, on the way to work, ostensibly to check up on me but mostly out of fascination with my cock. "Would you like me to kiss it?" she would ask coyly, and when I pretended indifference she would kneel in front of me, looking up seductively into my eyes, and say, "Please let me suck it."
And I would get out my laptop computer and set it to video record as my mum stripped and knelt again and sucked my huge cock like a pro, using both hands about the shaft and looking up adoringly into my eyes. For me, it was a good way to start the day. For my mum, it was good practice. She was soon adept at swallowing my cum as it flooded her mouth, and she always left for work afterwards with a huge smile on her face.
And a plug in her pussy too, that she always made a point of showing me. She would pout when I refused her offer of sex, but as long as she got to make me come with her hands and her mouth, she was satisfied. It's not that I didn't want to fuck her - I certainly did - but I got more pleasure out of knowing her pussy was wet and willing.
Besides, the experiment I was doing with her was specific. I wanted to see what the effect on her was of swallowing my cum. That was the main purpose of filming her - although there was of course entertainment value for me in the porn clips I was editing for myself. "What do you think?" I asked her after a week, and she blushed as she watched her mouth stretched wide about my cock, her throat visibly working to swallow my cum.
"Please don't let anyone else see that," she said.
"Not even Dad?" I teased.
"Especially not him!" she hissed.
I laughed. "I won't," I said. "But look closer." I put two clips side by side. "This clip on the left is from seven days ago, and this clip on the right is from yesterday."
She watched the two clips intently, studying them carefully. "Maybe it's my imagination," she said, "but I look younger in that one." She pointed at the one on the right, where indeed her skin looked smoother. "Maybe that's why I've been feeling good about myself in the mornings."
I forwarded the clips to a part where her breasts were the main focus, swinging beautifully beneath her as she licked along the length of my shaft. In the clip on the right, they were definitely perkier. Perhaps even a cup size up. "No wonder my bra was so uncomfortable today," she murmured. "I thought it was just because of how constantly horny this damn plug makes me."
My horny mother stared at herself in the mirror across the room, and sighed. "I do look younger, don't I? It's not that I haven't noticed the changes, I just didn't dare believe."
"It's not just you," I said. "Consuela looks ten years younger than she did. She says she feels ten years younger too, and her husband has certainly noticed. She says he can hardly keep his hands off her."
"It's not fair!" my mum cried suddenly. "Why are you fucking Consuela when you could fuck me instead?"
"Why haven't you found me some posh pussy to seduce yet?" I countered.
"Because you wanted someone rich, pretty and young. Now, my boss is rich and, I suppose, quite attractive, and her daughter is certainly pretty. Blonde and bitchy too, always coming round the office to beg money off her mum. I'd love to see her tight ass stretched by your thick cock..."
The vengeful gleam in my mother's eyes stirred my slumbering cock. "What about the father?" I asked.
"Oh, they're divorced. He married some girl his daughter's age."
"Sounds perfect to me," I said, stroking my hard cock gently and enjoying the hot lust in my mother's gaze. "As a reward, you can ride my cock for one minute."
My mum practically tore her clothes off in eagerness. Quickly naked, she extracted the plug from her cunt and sucked on it briefly, tasting herself while looking into my eyes. Her body had been in good condition before she had started drinking my cum, but now there was something almost feline about her. Just staring at her was almost enough to make me come. The smell of her cunt made me dizzy with lust for her.
Straddling the chair that I was perched on, she lowered herself until her pussy was pressed against the tip of my cock. "One minute exactly," I said, "starting now."
Gritting her teeth, she lowered herself onto me, panting heavily as her pussy was stretched wide by my slowly penetrating cock. "Fifty seconds," I noted.
"Damn you," she muttered, and lifted herself until I almost slipped free of her again - and then she dropped down. She screamed as fully half my cock thrust up into her, a rush of sensation that brought me close to the edge.
Her breasts were perfectly positioned for me to kiss. I sucked on a swollen nipple and bit it gently, while encouraging her with my hands to take still more of my cock. "Forty seconds," I whispered.
She lifted again, and thrust down, and after a few such efforts was able to ride my cock. "It's so big," she said between ragged gasps. "So fucking big! I love it!"
"Twenty seconds," I said.
She picked up the pace, slamming down hard, wincing whenever I bumped against her cervix. "Come inside me," she urged. "It's okay. It's safe. You can come inside me."
I was so very close, but her minute was up. "Sorry," I said. "Time's up. Fetch me your bra." She whined with complaint as I lifted her up off my throbbing cock, but quickly fetched me her bra, a sexy red lace bra that I held to my cock just in time to catch the torrent of cum that issued forth. A sweet orgasm made sweeter by the hunger in her eyes as she worked herself to her own climax with her fingers.
The material was soaked through with slimy cum when I was done. "Don't wear bras from now on," I said. "Your tits are too beautiful to hide."
She looked down uncertainly at her bare breasts. "Okay, Andy," she said. "Do I still need to wear the plug?"
"Whenever you're not at home," I confirmed. "Now, take me with you to work. I'm eager to meet your rich and quite attractive boss."

For once, I didn't mind letting my mother push my wheelchair. Usually I preferred to use my own strength. I didn't like feeling dependent in any way on other people, especially in public. Perhaps it was the knowledge that the woman pushing me, my own mother, had just frantically fucked herself on my cock and was hungry for more. Perhaps it was the fact that she wore no bra beneath her cotton shirt, and her swollen nipples now made sharp points in the material. Perhaps it was because my reborn testicles were like a fountain of youth. Not only was my mother a slave to my whims, she looked ten years younger and ten years sexier than she had just a week before.
