Julie giggled,
“If you do I will too.”
Robbie sighed and smiled,
“You two are amazing, I’m so glad I have such a sexy Mum and Sister, I love you both so much.”
“Awww, likkle Wobbies so soft,” Julie teased as she stroked her brothers chest.
“Ok,” said Sally, I’ll clean this up and Julie can try it for size,”
“Wearing it or having it?” Julie asked with a smile.
“Either way, I’m as happy giving as recieving, you choose.”
“I want to do you, as I want Robbie in me before I try anal, is that ok Mum?”
“Sure, I’ve had cock before, but I’m very much looking forward to Robbie’s little monster inside me, so OK, do me first.”
Sally disappeared to clean the dildo leaving Julie and Robbie sitting on the floor. On a whim Julie hooked her arm over Robbie’s shoulder and pulled him to her. She kissed him passionately feeling him respond, they traded tongues and pulled themselves together enjoying the feel of their naked bodies squashed against each other. They didn’t notice Sally come back in and sit down next to them, she smiled and put her hands on each of their backs, gently rubbing. Eventually they broke apart and grinned at each other. Sally leaned in and they kissed her in turn, their tongues swirling around each others.
They hugged for a while before Robbie sat back and said he wanted to watch the two women use the strap-on. They smiled and Sally passed the strap-on to Julie, helping her to harness it up tightly. Sally massaged the plastic cock and slipped it into position. Julie asked Robbie to lubricate the cock, which he willingly did. His wrist action soon had the dildo gleaming. Sally moved onto her hands and knees and waited whilst Robbie gently prised her cheeks apart and carefully lubricated her anus. Using Julies technique he managed to put two fingers into Sally, up to his knuckles, gently pushing and pulling. Sally gasped and began to rock with his finger motion. Robbie pulled his fingers out and held Sally’s cheeks open as Julie slowly pushed the plastic cock into her mother’s puckered brown ring. Sally squeaked as the head went in and Julie stopped for a couple of seconds before starting a slow rocking motion. Robbie disappeared under his mother and she sighed as his tongue ran along her slit and his hands massaged her breasts.
Julie pushed a little harder and each time she pushed in a little more disappeared into Sally’s anus until at last the strap-on was fully in her Mums dirt box. Sally gasped and sighed as her bowels filled with her plastic friend, her pussy was wide open where Robbie had brought her to the edge of a climax. When his two fingers entered her vagina, she grunted and screamed, driving her cunt onto them, then reversing the move, pulling out but pushing the dildo deep into her. Robbie’s other hand gently rubbed and teased her nipples. Sally felt the first wave of her orgasm hit, then everything slowed down as her universe dissolved before her.
There was only intense pleasure and pain, multiple colour flashes and a roaring sound. Julie and Robbie were amazed at how Sally’s orgasm ripped through her causing her to twitch and spasm on his fingers and the dildo, they gently pushed or pulled to maximize her pleasure. After so many climaxes she’d lost count, lost her voice and her sense of time, Sally fell sideways jerking the plastic cock out of her, as well as Robbies fingers and tongue. She lay twitching on the floor, eyes closed, moaning. Robbie and Julie looked at each other in fear and surprise.
