An encounter with Dave

Rachel stood at the bottom of the stairs, waiting for Cassandra.

"Where are the guys?" Cassandra asked.

"I don't know," Rachel said, "they all left."

"Damn," said Cassandra, sharing a moment of disappointment with Rachel.

Suddenly, Rachel perked up, "hey, is that your brother over there?"

"What?" Cassandra turned around and sure enough, there was her brother Dave, walking in through the turnstiles at the front of the gym. "Shit," she said, but it was already too late. Rachel was waving and beckoning him over.

"Hi Dave!" Rachel grinned.

"Hi Rachel," Dave greeted, "hey Cas."

"Hey Dave, what are you doing here?" Cassandra asked, "Curious to see what the inside of a gym looks like?"

"Har har." Dave replied, deadpan. "As a matter of fact, I'm here for something important."

"Oh really." Cassandra folded her arms. "And what could that be?"

"Well, if you must know," Dave pulled a small laminated card out of his pocket. "It so happens I have a Breeding Pass, and I figured this would be the perfect place for me to find some hottie I could use it on."

Rachel blinked.

Cassandra's eyes went wide. "Oh my god! Give me that!" She launched forward and snatched the card out of her brother's hands.

"Hey!" Dave complained, "you have no idea what I had to do to get that!"

"Shut it, freak," Cassandra said. Why would anyone give Dave a Breeding Pass? He's the kind of person who would probably lose it after barely getting his dick wet, and then spend the rest of the day moping about as he watched everyone else have all the fun. Cassandra examined the card. It looked genuine. It even had the fancy hologram in the top right corner. Awesome! With this card, she and Rachel could...

"Oh. Fuck," Cassandra said, making eye contact with Dave. A familiar and urgent feeling of arousal flowed through her body. Her brother had given her this Breeding Pass. "Fuck. Shit. Fuck."

Dave gave Cassandra a blank look.

"Ugh." Cassandra grabbed her brother by the hand and pulled him up the stairs with her, back towards the employee break room.

"Cas?" Dave simply followed in bewilderment.

Cassandra couldn't believe this. She had been spending the entire day trying not to have that pudgy kid's ugly brat, fucking who knows how many men, and now, after all that, she was about to have her own brother's little mutant inbreed. All because of one stupid brash act on her part. She should never have taken her brother's Breeding Pass. She shouldn't have even looked at it. How did he even get one to begin with? And why on earth did that idiot think he could show it to his sister?

Cassandra barged into the break room with Dave in tow. Jasmine was sitting on the couch, playing with her phone. She got up at the intrusion. "Hey! I warned you I would call the cops," she said, brandishing her phone.

"Breeding Pass," Cassandra said, showing Jasmine the card.

"Oh." Jasmine sat down and went back to playing with her phone. "Carry on."

Cassandra shoved Dave onto the couch next to Jasmine. She peeled off all her clothes, for the upteenth time that day. She briefly wondered why she had even bothered to get dressed that morning. She hopped naked onto Dave's lap.

"Cassandra what..." Dave began, but Cassandra silenced him by shoving his face into her boobs. She might be fucked, figuratively, and in a moment literally, but she was at least going to savor this. Having sex under the influence of a Breeding Pass was an experience quite unlike anything else.

Cassandra got up and tugged Dave's pants down. His cock popped out, rock hard and ready. "Oh my god, Dave, how are you already hard?" Cassandra asked, stroking his cock slowly.

Dave shrugged.

"Does seeing your sister's naked body turn you on that much?" Cassandra gave the tip of Dave's cock a playful lick.

"Holy shit," Jasmine interjected, "you used a Breeding Pass on your sister? That's so nasty." She put her phone away and started watching Dave and Cassandra.

Dave gave Jasmine an embarassed grin, but it was quickly replaced by a moan as his sister's mouth engulfed the head of his cock.

Cassandra did not waste too much time giving her brother a blowjob. She mostly just wanted to get his dick slick with saliva, and maybe tease him a little bit. She got back on his lap, this time facing away from him. She placed his cock right at the entrance to her pussy, and paused.

Cassandra looked back at her brother. "You said you wanted to knock up a gym hottie, didn't you?"

Dave could feel Cassandra's wetness dripping around the head of his cock. He nodded.

Slowly, Cassandra lowered herself onto Dave's cock. When he was fully inside her to the hilt, they both moaned in pleasure and relief. 'Goddamnit Dave,' Cassandra thought as she slowly moved up and down, 'why does your dick have to feel so good?' Even though her body craved Dave's seed, she tried not to go too fast. She knew Dave didn't have all that much sexual experience, and she wanted him to last for at least a little while. Cassandra touched herself, and pleasure filled her body both from her own touch and from Dave's cock.

Cassandra wanted to keep things slow and steady, but apparently Dave had other ideas. He grabbed Cassandra by the boobs and pulled her into his chest. "Oh, fuck!" Cassandra exclaimed as Dave started thrusting into her, fast and hard. Cassandra's first orgasm on her brother's cock took her completely by surprise. Through her waves of pleasure, and Dave's thrusting, she felt his cock pulse and throb. It felt like Dave was going to cum any second.
