Though she'd grown horny, she'd thought of Razor. "He's gesturing for us to pull over," Razor explained.Tina looked back at the truck. Sure enough, th...e trucker had turned on his interior lights, too, and was repeatedly pointing to the shoulder of the highway.Not knowing what else to say, Tina had taken a deep breath and said, "If you want me to."Just as she finished saying that Tina had been thrown forward as Razor slammed on the brakes. Okay, she had thought, no biggie, I'm going to fuck a. And it was highly unlikely that big, strong, virile Sam was shooting blanks.Returning from the bathroom, she was unsurprised to find that Sam and Nina were making love. What was surprising was how gentle it was; slow, leisurely and almost silent. Nina was sitting on the padded seat of one of the exercise machines, and Sam stood between her parted legs and moved inside her with slow soft srokes. Instead of their usual lusty gasps, grunts and moans, the two siblings were sighing and whispering. Moving his eyes higher until his gaze was on her panties, he could see the noticeable darkening of the lacey material. This was telling him volumes about how easily Meagan was going to be to break to his will. Moving his gaze further up until he was admiring her breasts hidden by the matching bra. He thought, not large, but very nice. He finally moved his gaze to her face, seeing her staring back at him. He’d seen all he wanted for now. She was trainable, but there was one final test to see how. She removed her mouth long enough to say "are you ready for this?" and "I want you to cum in my mouth." Her body spasms began to intensify as her orgasm came to a peak. She slammed her pulsing cunt down on my face as her orgasm reached its peak and she exploded. As the hot sticky fluid flowed out of her pussy I lapped it up as fast as I could. It was at that point that I noticed that she had begun to lose control of her bladder during this intense orgasm.Her mouth enveloped my cock as I came.
