Hot bed rodeo

As the married couple tied up their fuck buddy Claire to the bed they were already quite visibly aroused. It was obvious that this wasn't a one-time affair; both had been planning to spend the night with her and, judging by how much time they spent on foreplay, it seemed very likely that there would be more than one encounter.
Claire felt like she could almost hear the two of them having sex as they did so in the next room over. She couldn't see them from where she lay bound to the bed, but she could easily imagine what they looked like through the doorway. The wife was on top of her husband, riding him hard while he pounded away at her, his hands gripping her hips tightly as he pushed deep inside her again and again. He reached around to grab her breasts, pulling and squeezing them roughly before pinching her nipples between thumb and forefinger.
Claire could feel the freshly charged vibrator in her as she neared her first orgasm, it was going to be a long hard and wet night.
"Oh god! Oh my god!" Claire moaned loudly. "That feels so good... I'm gonna cum..."
The wife gasped loudly at the sound of her own voice when the sudden sound of Claire’s moans with the vibrator pushed her past her limits. Her body tensed up and then released a flood of juices down onto the sheets beneath her. The man grunted and groaned heavily as he thrust into his wife's pussy harder and faster than ever before, driving himself deep inside her as the orgasm hit him.
Claire was already past her first orgasm and was painfully moving onto her second. She could feel it building inside her, ready to explode in an instant.
Her eyes rolled back and she let out a high pitched shriek as she finally reached her peak, her entire body spasming uncontrollably for several seconds as waves of pleasure coursed through her.
