They totally do it.

Alex walked over to the girl duct taped to the coffee table, he loomed over his panting prisoner, and tore the sweat soaked piece of tape from her mouth.

Lina smiled coyly at Alex, her eyes slowly panning up to meet his.

"Are you going to keep a girl waiting?" She said rely.

"I just wanted you to know that I know how to show a girl a good time" he rebuked.

"Well, I usually save parasitic worms until the third date, but I guess that I'm a little traditional."

Alex giggled, but his demeanor changed instantly as took a heavy sigh. "I'm sorry I did this to you" he said as he averted his gaze.

"Untie me so that I can take your mind off of it"

Alex looked her over for a second and began to peel more tape. When she was finally free she stood up quickly and stretched. After a moment, she finished un-knotting her back and turned toward Alex with a devilish grin.

"What?" Alex asked.

Without saying a word she leaped at him, arms open wrapping him in a hug that knocked him back on the floor. Before he could react, Lina was kissing him deeply, he hands sweeping though his hair. Alex could feel the hardening prick tingle as the voice in the back of his head rose in volume once more. Lina could sense the maddening need in him, and she reached down with one hand to slowly stroke the worm. He thighs tightened around his abdomen to hold him down, while she straddled him.

She worked her pelvis back and forth, grinding against his belly, leaving a trail of hot slime. He pussy practically drooled, as the fire crept through her. Whatever the worm did to her, she was loving it. Finally she couldn't resist any more and she positioned Alex's dick, slowly angling it until she aligned the tip of the prong with her wet entrance.

His first thrust was excruciatingly slow, and the movement drew gasps from both of them. As he withdrew for another thrust Lina cooed in pleasure. She screamed in ecstasy, trying to maintain her vertical position. It took her a few minutes to overcome the initial bliss, and then she kept moving down, letting the long shaft move deeper inside of her lubricated pussy, little by little, until it was completely engulfed.

She knew her climax was close and she began to move faster. Up and down. Up and down. The head of the prong was slamming against her cervix and this was a new feeling for her. She had never felt so full in her life. She had never felt sex like this before. Lina knew that the orgasm building in her was going to be epic. It was close now. Closer...

Alex began working the creature in, and out of her, gradually increasing in speed, until Lina couldn't take it anymore. She screamed in pleasure and bent forward, to rest her head against his neck. Alex never slowed, but he grabbed her narrow waist and pumped violently.

Lina whispered in staccato from the pounding: "Fuck me, I need your cum inside me."

This pushed Alex over the edge, and the worm began to wildly spasm, erupting inside of the girl.
