Arthur knew what that was code for.
Arthur grinned and stood up on the bench, then lowered his testicles to Mindy's mouth. She licked each warm globe before sucking them into her mouth one at a time. She even licked that flap of skin between the balls and the anus, but she mostly just tongued his balls and lower shaft while a steady pressure built up inside her body.
Robbie's tongue and fingers were more than doing their jobs as Mindy neared climax, then the dam finally broke and she spilled onto his hand.
“Switch again?" Arthur asked politely.
“Why not?" Robbie replied. Arthur reluctantly moved away from Mindy's mouth and got between his favorite lover's thighs, sliding his now-hard prick into her slick pussy while Robbie offered her his semi-flaccid member, which she gratefully took into her mouth and started to nurse back to health. It was Robbie's turn to groan, as his meat was still sensitive from having climaxed. Luckily, the little hellcat that was sucking him was quite adept at the oral arts, and he found himself returning to full strength while completely engulfed in her maw. After he was completely stiff again, she let his cock slide out with a "plop" and started sucking on his heavy balls, her hand stroking his shaft.
Arthur was just relishing Mindy's tight cunt, feeling its velvety grip on his rod as he pumped her with a good, steady rhythm. Her legs wrapped around him, enjoying his leisurely fucking while she orally stimulated the living hell out of Robbie. She was done playing with his balls and was deep-throating his substantial rod again, her lips cupping his balls as they pressed against her chin.
“Wanna try something new?" Arthur asked innocently.
Mindy barely heard him over the sloppy blowjob she was giving, but she knew something was up when Robbie . . . slowly . . . pulled his entire length from her mouth. Arthur grabbed her hips and managed to get both their bodies to roll sideways so that Mindy was on top with Arthur's cock still inside her.
"What . . . what did you have in mind?" she asked as his cock continued to penetrate her.
Suddenly, Robbie was behind her and Mindy almost panicked. She had seen Anya in this position many times, and she wasn't sure she was ready to handle anything bigger than a finger up her behind. She had considered letting Arthur have THAT privilege but . . . Mindy felt something unexpected. Robbie wasn't pushing his cock into her asshole.
Instead, he was pushing it into her pussy, just above where Arthur was embedded.
"No way," she moaned, torn between nervousness and desire, "you can't possibly fit both those things . . ."
"I'm pretty sure we can," Arthur said, pulling her ass-cheeks apart so Robbie could see what he was doing.
"You took Tarloh in there, and neither of us are nearly that big."
“But . . . together you two are . . . oh God!"
The head of Robbie's prick had slowly found its way inside, pushing down on Arthur's cock as it tried to make room. Robbie was obviously not going to rush this. Arthur had stopped moving, and had to admit to getting a bit of a thrill when he felt something sliding against his member which was already under tremendous pressure.
Mindy felt like a ten-pound turkey being filled with eleven pounds of stuffing. It was so much headier of an experience than just having a big dick in her. Even with Arthur becoming more passive, he was moving a little and Mindy had man-meat going in two different directions in the same confined space, and her brain was completely unable to process the experience coherently. The only thing that was clear to her . . . she liked it. She had never felt that filled, and she wanted more.
“Fuck me!" she barked as her vaginal walls relaxed a little. Robbie started to fuck her as fast as he reasonably could, the head of his penis sliding over the mushroom head of Arthur's member as it went in and out.
But Robbie had one other trick to play, and he pushed his thumb into Mindy's butt-hole. That actually caused the girl to screech before she covered her mouth, her eyes wide with surprise. And when Robbie's other thumb worked its way into her sphincter as well, she sort of collapsed against Arthur's chest while the two handsome men used her body as they willed . . . she wouldn't argue with them even if she wanted to. But she started getting more lively again as she felt another big orgasm coming up. Someone's dick was banging against her g-spot which, combined with her sense of fullness in her pussy and having thumbs in her ass, was going to cause her to erupt.
"I'm. . . gonna . . . oh, please, make me cum!" she whispered.
"I'll do one better," Arthur said, placing one hand between their bodies and concentrating his magical energies towards her crotch.
Mindy's brain began to glow . . . that was the only way she could possible describe it. Arthur had done this before . . . using his magic to amplify the power of the pleasurable nerve-endings in her pussy and brain during climax. Stacked on top of what was already going to be the motherload of all orgasms.
"Oh . . . oh . . . OH!" Mindy's body froze almost solid except for her head and neck that were arched back, her mouth and eyes locked in the open position. Her pussy squeezed down on both cocks in her pussy as she unleashed what felt like gallons of girl-jizz onto both invading members.
"Holy shit!" Robbie said, feeling his own member ready to burst under the pressure. And he could feel the underside of Arthur's cock against his own and could feel the sperm swimming upstream, and both men blew their sticky loads into Mindy's vaginal cavity.
