He Drops His Pants

Sam, encouraged, unbuttoned his shorts and pulled them down. His large, thick cock was well on its way to an erection in response to Marie's teasing. Marie tried to play it cool, but half a stifled gasp escaped her pursed lips.

"Well now," Marie said. "I thought I knew all the stallions in this rodeo. How have we not tangled before?"

"It's my second day here," Sam said matter-of-factly. "My dance card's been pretty full..."

Marie step close to him and began fondle Sam's cock and balls, coaxing him to full hardness.

"I see," she said. "Well I'll just have to make sure you hold space for me." Marie grabbed Sam's wrist and moved his hand to her ass. He grabbed and massaged her soft, jiggly cheeks as she lubed up his hard cock hard with her hands and mouth. He played with them, spreading her ass and making it shake. She leaned in and moaned a little in his ear.

"I can't wait for you to split me in two, Sam," she whispered into his ear. "I'll tell you a secret: I don't need **** to cum on a cock in my ass.”

With that, she turned around and gave her thunderous ass a shake, drawing Sam and his huge dong like matador’s red cape. He approached and slide his cock between her ass cheeks as she jiggled for him, dripping the spittle on his dick down onto her butthole.

“You ready?” Sam asked. He was being courteous, but you there was a cocky edge to the question.

“Honey I’ve bee… Ngggghhhhhhhhh,” Marie groaned as Sam pushed the head of his cock inside and pulled her body in. Despite all the big talk, Sam was going to need a minute to work her in. He sawed his cock in and out of her ass, pushing in a little deeper each time. Each thrust seemed to bring new and previously unknown pleasures to Marie.

“How are you feeling?” Sam asked after the first five minutes, as the test protocol requested.

“I can feel every inch of me wrapped nice and tight around every inch of you…” she moaned dreamily.

"So... Good?" Sam said, checking a box on the clipboard next to them.

"amaaaaazing," she confirmed. "It almost feels like your fat dick is making high... And I'm ready for a big hit."

Marie started to push back on Sam's cock, pushing him in harder and deeper than before. He took the hint and started thrusting hard, making her ass jiggle as he resized her asshole. Before too long, he was fucking her with full, ball-slapping ****, and making her scream incoherent erotic exclamations.

"God you make me feel like such a SLUT!" She screamed. "Fuck my ass til I'm pregnant! FUCK FUCK FUCK FUCK."

They just continued on like this for a long time--15-20 minutes, maybe. By the time Sam was ready to cum, most of the other test couples had already finished. Some of them were watching. Some were getting ready to go. Dr. Ironrod observed, pull his chair arguably too close, while taking copious notes. As he wrote, Marie, alternated between trying to tempt him and call him out.

"You know there's room for you in this pussy, doc..." she said breathily between cock-induced grunts. And when he didn't immediately respond, she'd spit at him and shout, "Fine! It's your loss." Then she'd lose herself in orgasmic bliss all over again. Sam, for his part, was too focused on fucking to notice anything else going on. He was entranced by Marie's jiggly, but tight behind, which is the only reasonable explanation for how he could keep going.

Eventually, after about an hour, Sam finally came with a groan. Slamming burst after burst of thick semen into Marie's ass. She was already packed so tight, he wondered if his cum had shot up into her stomach. When he was done, he slumped over, pulled out, and lay down on the floor. Marie did the same. It seemed like they would both need a minute before they could gather themselves and get dressed.
