Jake takes the initiative

Even without words, Jake was able to see Abbie's actions and trust what the next step was expected to be. As Abbie held the back of her panties, Jake took hold of his dick, and pushed the tip of it against Abbie's pussy. She was already very wet, and Jake slid inside her easily.

They began to fuck, rather slowly at first. They were aiming to remain as quiet as possible. Abbie put her hands behind her and touched Jake's hips. Jake had one hand on Abbie's back, near her shoulder, and the other wrapped around her front, fondling her breasts through her clothes.

Abbie pushed her ass back against Jake as he thrust into her. She loved the feeling of his body against her as he fucked her from behind like this. And moving slowly and cautiously meant lingering at that point on each thrust, holding still as his cock was at its deepest point of penetration.

As for Jake, each time he reached that peak, he could feel the tip of his dick along the inside of Abbie's vagina, feel the pressure, the friction, the warmth. He pulled her body back against him, and then relaxed his grip on her and withdrew. Then another thrust, and another.

The entire time, Jake was plenty excited simply to be having sex with Abbie -- but he knew that something else was going on around the corner of that shelf, something he couldn't see. He was so curious, but for the moment, had to let him imagination run wild. He hoped that Abbie would facilitate a shift in their position so he could get a view of whatever she was watching.
