It was that song from before, back when she groped him. And just hearing that tone worm its way into his head... Gregory shuddered underneath her as he felt his blood rushing yet again. And as his body was made more susceptible to her lustful suggestion, he became more and more aware of the soft, rubbery form squishing on him. And he also became aware of how thin the suit Glamrock Chica put him in. At this rate, that animatronic might notice-!
"Hm?" Gregory froze up at the curious tone Chica let out. Curious, she rolled her hips, and Gregory could feel those sculpted cheeks rub around his bulge. The boy shivered underneath her. He wanted to defend himself, but he had no room to move. He couldn't lift his arms, so he couldn't push her. And she was far too heavy for a guy like him to lift purely with her hips. And even then, his hips were... doing something else... Color came to his cheeks as that voicebox manipulated him like a snake charmer, and his hips wiggled against her. And as if that wasn't bad enough, the rockstar looked over her shoulder down at him with a half-lidded expression before fluttering her eyelashes.
"Oh, did mama work you up a bit too much, my cute little Chickadee~?" she cooed. She chuckled and rolled her hips again, now starting to get in tune with Gregory's wiggling hips. "Hmhm, it would be a bit hard to sleep with that distracting you, wouldn't it? Don't worry, mama can relieve you!"
"W-wait-!"
However, Glamrock Chica gave him no such mercy. She spread her legs to make sure to lean more of herself down on the boy's lap. Now he could feel more of her squishy butt. It seemed to mold around his bulge, eagerly accepting him as that voicebox forced him to shake his hips. The trespasser shuddered and tried to fight that feeling, but his mind was being pulled in too many directions. Chica continued to undulate her form upon him, as if she were doing some rapid squats.
"This can be a good exercise for mama too, my adorable Chickadee!" she cheered as she rubbed down on him. Up and down she rubbed, up and down she rubbed. And at the same time, Gregory's body was forced to pull away when she got up, before lifting into her when she went down. It didn't take long at all, but he was already close to finishing. Chica seemed to realize that too, because when she felt that shake coming, she squeezed her hips down to squish into the base of his dick, and grind left and right against it. And that simple motion would do Gregory in, forcing him to cum again!
"A-agh! Mmgh!" He extended his hips as he was forced to blast against her, with the exerciser continuing to grind side to side on him to really draw out as much of him as she could. He was left huffing and puffing and blushing deeply, only to find that the voicebox kept playing, and she kept on rubbing on him. "M-mgh...? What are you...?"
"I just need to work out every last bit of stress you have," she said as she rubbed around on his lap. "You don't have to worry about messing that new suit up, my pent up Chickadee. I've got plenty more where that came from!" She giggled and kept rubbing on him while Gregory was left at her mercy. Not even his body was completely in his control, his hips kept rubbing against her, and she played along to the tune she was creating. If this kept up, he'd be drained and tired out for sure...
