Below Robert and Jess, Amanda jumped as the bed collapsed. Roberts room was directly above her and she could hear them talking to each other in lowered voices. Amanda's blood was boiling. At first she had been scared, terrified in fact. For the first few minutes after Robert and Jess went upstairs to fuck, Amanda had just sat down and cried. But now she was enraged. That was HER gun; SHE should be the one who was big and powerful. She began creeping up the stairs towards Roberts room, her tiny body moving soundlessly over the same stairs that had creaked and groaned when Robert went over them.

Jess lay next to Robert, running her fingertips over his chest abesently, trying to figure out what it was Robert had done with that gun. Her boyfriend’s new body had her turned on but the thought of being as big and buff as he was turned her on even more. "So, what do we do now?" Robert asked again.

Jess grinned wickedly as inspiration struck. "I have some ideas," she whispered to him as her hand drifted down lower and brushed against Roberts cock. It stirred almost right away and her grin widened. "Why don't you just lay back and enjoy this honey?" she purred as she rubbed her body against his, getting both of her hands on his stiffening member. He leaned his head back and closed his eyes, clearly enjoying Jessica’s ministrations.

Jess glanced around again and still couldn't figure out what Robert had done with the gun, she had been so horny she hadn't been thinking enough to pay attention, but that was ok. That could work both ways; she was going to get what she wanted no matter what. She had one hand clenched around the base of his dick as the other stroked and pawed at the lengthening shaft. Robert groaned with pleasure as Jess began using her tongue in quick darting motions against the tip. His dick grew thicker and thicker as he became more aroused, she could feel it spreading her fingers apart regardless of the tight grip she had on it. Now she was using both hands to stroke up and down the length of his shaft while her tongue continued to tickle and prod the most sensitive spots at the tip. Roberts’s hips began to buck slightly as he prepared to blow another load, his penis throbbing in her hands. Jess couldn't even get both hands around it now. Robert moaned, a low and long sound that suddenly turned into a yelp. "What are you doing Jess? That hurt."

Jess held onto Roberts dick as hard as she could, her fingernails digging into it roughly and she glared at Robert with a grim expression. "Robert, this may be loads of fun for you but it's just not working for me ok?"

"What are you talking about?" Robert was clearly frustrated, his hips bucked slightly and he squirmed at the uncomfortable sensation. "Why did you stop sucking me off?"

"Because I want to FUCK Robert. I want to feel this enormous dick inside of me, and that won't happen unless you make me as big as you are. And if I'm not going to get what I want you're not going to get what you want either."

"But Jess..." Robert stopped talking as Jess stopped digging her nails into him and ran her tongue slowly up the entire length of his shaft. "JESSSS!!!!" he moaned when she stopped again. "C'MON!!"

"I can keep you right at the edge baby. I can keep you there all. day. long. What are you going to do about it?" Jess smirked at him before opening her mouth as wide as she could, wrapping her lips around the tip of his huge penis and taking as much as she could. Robert moaned and then yelped again as Jess roughly dug into him with her nails another time.

"Fine, fine. Damn is Jess, I need to cum... Fine!" Robert staggered to his feet and grabbed the gun off the top of some shelves. He glanced at the dials and tried to figure out what settings he should use on Jess to get the best fuck possible out of her.

Behind Robert, behind his partially closed bedroom door Amanda was crouched just outside, intently watching Robert as he messed with the dials on the gun. Finally Robert aimed the gun at Jess, “Get ready babe, here it comes.” He pulled the trigger and Jess squealed as the beam hit her.
