When her family needed help. My wife sent me.
It will help you understand this story if you read Chapter 1 and 2 first.
Jack and I were in the men's shed having a beer. Jack looked at me,"I can hear the cogs slowly clunking together." he said with a laugh, "What are you thinking about?"
"I'm thinking I wouldn't mind taking mum back down to that nudist beach." I said, then went on,"You think if we take her down there without the girls she would let us spit roast her on the beach?"
"Only one way to find out," he said, "Lets go ask her."
Jack chucked his empty beer can in the trash can and headed for the house. I tossed my empty can and headed after him. We went inside, and found our mother in law, Beth at the kitchen sink. Her beautiful round butt twerking as she scrubbed a pot. "Hell mum, hold your butt still will you," Jack said, "You're giving Bill a hard on."
"You perving at me again?" I asked Jack.
"No man, but I couldn't admit she was giving me a hard on could I?"
"If I'm giving you both a hard on, I'm happy." Beth said. Twerking her butt some more.
"Mum, we were thinking," I said, "We would like to take you back to the nudist beach, and show you off again."
Beth reached for her shirt and pulled it away from her chest so she could look down at the hickeys she wore proudly on her left and right breasts. "I'd like that." she said, "The girls are out shopping, should we call them, or wait for them?"
"We were thinking of taking you on your own." Jack told her.
"OOOHH, I like that idea," she said, "Could we, maybe, get up to some mischief down there."
"Jack and I thought it might be fun to spit roast you down there."
"So, Why are we all still standing here?" she asked, heading for the door.
We were right behind her. The three of us jumped in the car and headed for the beach. "Are you on the pill yet, Mum?" I asked
"I've started." she said, "But you can't have me yet."
"But don't worry, you won't miss out." She licked her lips hungrily.
I almost came in my jeans. Once we got to the beach Jack and I stripped then we helped mum to undress, we stuck all our clothes into a bag together. Our mother in law linked her arms through mine and Jack's, and the three of us walked along the beach arm in arm. People looked, people stared, some made approving sounds, a couple of old biddies made tut, tutting sounds. We couldn't care less, we were totally happy with the way we were. Mum pushed her breasts forward proudly, so everybody that we passed could see that she wore our marks on her ample tits
A little way along the beach, mum guided us into a little valley between two dunes. "This looks like a nice spot." she said
Jack and I looked around, nice spot indeed. A little secluded so innocent people walking along the beach would not have to see us, but public enough that if somebody wanted to perv on us they could. I hadn't realized just how open minded my mother in law could be about sex. Jack slipped in behind her, and reached around to play with her tits, while rubbing his cock up and down the crack of her butt. I did what I like doing best. I sank to my knees and started to eat her hairy pussy, delighting in the taste of her sweet nectar as it poured out of her, and over my tongue. It didn't take us long, Jack and I brought Beth to her first climax in only a few minutes. She cried out her release as quietly as she could, but some people on the beach may still have heard her.
When she had regained some control of her body she reached down and helped me up into a standing position. Then she bent and took my cock into her mouth. Jack slid himself into his mother in law doggie style. I felt Beth groan on my cock as her filled her pussy with his cock. She was doing mine the way she had last time. The whole of my cock in her mouth, and then slowly hum, suck, and swallow, allowing my cock to grow to full hardness and grow straight down her throat. With my full cock down her throat, and Jack's cock fully embedded in her pussy, we all worked together to established a rhythm. I looked around, Jack looked around. Beth couldn't look around, so couldn't see what Jack and I could. On one side of us, a discrete distance away, a middle aged guy stood, stroking his cock. On the other side of us, stood a young couple. Him stroking his cock, and her furiously rubbing her pussy.
It was all too much for me. I wrapped my fingers in mum's hair and with a long guttural groan pumped my cum deep down her throat. After the first shot she pulled her head back so she could capture the rest in her mouth, and taste me on her tongue. I eased my now very tender cock from her mouth.
With my cock out of her mouth my mother in law could now look around. First she saw the older guy, then she saw the young couple. Seeing the young couple masturbating together sent mum over the edge. With Jack hammering his cock into her for all he was worth, she came again, in a screaming orgasm, which she did nothing to stifle. She screamed her pleasure proudly for all to hear. Sending her over the edge sent Jack over too. He drove his cock deep into Beth's pussy, and roared his release, pumping his full load of cum deep inside her.
The young woman squealed her climax, and gushed her juices down her legs. I don't think I've ever seen a girl squirt so much. Her man couldn't take any more. Seeing her cum set him off and he jerked his cum out onto the sand. I looked the other way, the older guy had cum and was gone.
Mum was shaky on her feet, Jack and I helped steady her so she could stay standing. Together, the young couple, my mother in law, Jack and I all walked into the water to get ourselves cleaned up. The young woman looked at mum's breasts, then looked up at her face, "You are owned by both of these guys?" she asked
"Only partly." Beth said. "I do have to share them with both my daughters."
"Holy Fuck." she said "are you serious?"
"Yes, dear, I am."
"That is just so fucking hot." the girl said, then turned to her husband "Baby, would you do that with my mum?"
"In a heartbeat, sweetie, In a heartbeat." he told her.
Jack and I linked arms with our mother in law and we all walked back along the beach, heading for the car park. When we got home Mel and Angie were back from shopping. Mel said to her mother. "Where did those two depraved animals take you?"
"In my mouth and in my pussy, why is that dear?" Then she couldn't contain herself any longer, she made the whole house ring with her peals of laughter.
"We took your mum back down to the nudist beach." I said
"And spit roasted her in the dunes." Jack added
Angie chimed in then, "You two really are animals," she grinned at both of us "Hope you saved some for Mel and me."
