They build up slowly

After zipping up the tent, Zack took off his boots and crawled onto the airbed with Heather. The pair spent several minutes kissing and petting each other. They took turns rolling each other over. Before things advanced, they lay on their sides, smiling at each other. When Heather looked into Zack’s eyes, she saw a bit of hesitation.

“Are you nervous, Baby?” she asked.

“A little,” Zack confessed.

“Can I ask you a question?”

“Yes,” he responded.

“How many girls have you been with?” she inquired.

“Two,” Zack informed his new girlfriend.

“Who were they?” she wanted to know.

“Lisa, and the mystery girl at Ashley’s party,” he replied.

“You never found out who that was?” she puzzled.

“Nope, but just to be on the safe side, I went and got myself tested a few times. No issues,” he reassured her.

Heather looked at Zack and smiled. Zack could immediately tell that she knew something about that night that he didn’t. He was just about to say something when she spoke.

“Would you like to know who it was, Baby?” she asked.

Zack contemplated saying yes for a moment, but not wanting to risk spoiling things with the woman in front of him, he chose to shake his head no.

“Unless it was you, it doesn’t matter,” he told her.

“That’s what I hoped you’d say,” Heather smiled and rolled him over onto his back. “Now don’t worry. You’ve been outstanding so far, so you should be great at this next part!”

With that, Heather took Zack’s shirt off and tossed it aside. Shen then leaned in and kissed him passionately on the lips. She hummed as her tongue entered his mouth. After a few seconds, his hands took a firm grip on her well-shaped ass.

“Mmm! Fantastic, Baby!” she sighed.

Zack’s fingers crept up Heather’s torso and played with the hem of her shirt, pulling it loose from the denim shorts she was wearing. Heather took the hint and let him remove her shirt. Zack smiled in approval as her white lace bra filled his field of view. Heather quickly undid the snap and took the garment off her body.

“You are so beautiful, it hurts!” Zack told her for the umpteenth time since they became a couple.

“That’s what I hoped you’d say!” she giggled before leaning over and feeding him one of her breasts. Instead of attacking her nipple, Zack gave the bud a swift lick to moisten it, then pursed his lips and exhaled on it gently.

“UHN! Zaaaaack!” Heather moaned as Zack treated her other nipple the same way. This little trick caused Heather’s already stiffened nipples to extend to maximum height.

“Where did you pick that one up?” Heather asked.

“A magician can’t reveal all his secrets,” he laughed, but quieted quickly when he thought Heather didn’t look too amused. “Saw it in a porno once.”

“You watch porn?” she smirked.

“Helloooo? Teen-aged male. It’s kind of a requirement for both my gender and my age group,” Zack laughed.

"Good. We'll have to watch some together," Heather laughed.

Heather continued to roar as she kissed down Zack’s stomach and undid his belt. She barely had it unbuckled when she ripped his shorts and boxer briefs off his body. His member stood fully erect. Heather took it in her hand and pumped him gently, making Zack tremble. Before she went too far, she flipped over on her back and pointed to the buttons on her own shorts. After undoing them, Zack removed Heather’s shorts, gently kissing her legs as he pulled them off her body. Zack then proceeded to take off her panties.

“You can keep those, Baby!” she told him as she lifted her legs, allowing him to fully remove her intimate apparel.

For the first time in their relationship, Zack and Heather were completely naked in front of each other. The pair spent a few minutes exploring each other’s bodies. The soft moans inside the tent grew as they stimulated each other. After about ten minutes, Heather looked at Zack and smiled.

“Make love to me, Zack,” she moaned, opening her legs to him. Zack fished out a condom, but Heather shook her head.

“No! I want to feel the real you,” she sighed. Zack dropped the little square package and sat up.

Despite his nervousness, Zack eagerly crawled his way up Heather’s body, trailing kisses as he went. When he looked into her eyes, he kissed her briefly. When Heather broke the kiss and nodded to him, he took hold of his cock, lined it up and entered her slowly.
