Jack recognises the voice

It is in that moment that it all becomes clear that the three of you were thinking with your horniness and not with any rationality. Was it hot that Mr Fowler had just moaned his son's name while cumming in his daughter's BF's mouth? Yes. Was it likely that the whole ruse was going to be up? Also yes.

Jack extricates himself from the older man's grasp and reaches up for his blindfold before any of you can stop him.

He registers his girlfriend, it is when he sees Liz and Mr. Fowler that his face drops. Emily still has her chin resting on her father's thigh, inches away from his deflating cum covered cock.

The cock that just came out of his mouth.

He still hasn't said anything but there is something like terror building in his eyes.

Liz acts quickly and gets up from her position next to her satiated husband. Her hand snakes out and grabs Jack's still rock hard cock.

"Look," she whispers loud enough for you all to hear. "You are still hard."

She starts to jerk him.

"I think you need some lube for what you are going to do next." She says.
