Fucked like a doll

Walter, still in the form of the blonde blow-up doll, shifted slightly on the floor, his plastic body making a soft rustling sound. He looked up at the boys with a mischievous glint in his eyes—at least, as much as a blow-up doll could.

"You know, there's one thing I haven't tested yet," he said, his voice slightly muffled but still recognizable. "I need your help with that."

The boys exchanged glances, their curiosity piqued once again. AJ raised an eyebrow. "What do you need our help with, Walter?"

Walter gestured vaguely with one of his plastic arms. "Well, I've transformed into this blow-up doll, and I want to know if the sensations are accurate. I need you boys to... interact with me as you would a real blow-up doll."

Jack, Ty, and AJ looked at each other, trying to hide their grins. Mike, however, blushed deeply and looked down at the ground, his scrawny frame shifting uncomfortably.

"You want us to fuck you like a blow-up doll?" AJ asked, a wicked smile spreading across his face.

Walter nodded, his plastic head bobbing slightly. "Yes, that's correct. And from the looks of your erections, I think you're all more than ready. So, what do you say?"

AJ looked at his friends, a mischievous glint in his eye. "Well, I'm game if you guys are. It's not every day you get to fuck a blow-up doll that talks."

Jack grinned and flexed his muscles. "I'm in. Might as well see what this thing can do."

Ty nodded, a playful smile on his face. "Why not? Let's give it a shot."

Mike, however, looked increasingly uncomfortable. "Guys, come on. It's still my dad in there," he protested, his voice barely above a whisper.

Walter, still in the form of the blonde blow-up doll, turned to Mike. "It's alright, son. I want to experience this. Besides, it's not every day you get to help your old man with an experiment."

Mike hesitated, his face red with embarrassment. "I don't know, Dad. This is just... weird."

AJ clapped a hand on Mike's shoulder. "Come on, Mouse. Where's your sense of adventure? Besides, it's not like he's asking you to do it. We'll handle this."

Mike took a deep breath and nodded reluctantly. "Okay, fine. But I'm not participating. I'll just... watch."

The other three boys exchanged smirks and started to unbuckle their belts, their erections already straining against their pants. Walter, the blow-up doll, lay back and spread his plastic legs in invitation.

Jack was the first to step up, his 8-inch cock already hard and ready. He knelt between Walter's plastic legs and positioned himself at the entrance. "Here goes nothing," he said with a grin.

As Jack pushed into the doll, Walter let out a muffled moan. "Oh yes, that feels... different."

Ty and AJ followed suit, taking their turns with the blow-up doll. Ty's massive size had the plastic stretching to its limits, while AJ enjoyed the unique sensation.

Mike watched, his face a mix of curiosity and discomfort. He couldn't help but feel a twinge of pride that his dad was pushing the boundaries of technology, even if it was in such an unusual way.

After each boy had their turn, Walter shifted back to his original form, his body shimmering as he reverted to human shape. He looked at the boys with a satisfied smile.

"That was... enlightening," he said, his voice back to normal. "Thank you, boys. And for your assistance, I owe you a favor—one that you can call in immediately if you wish."
