Not a question of if he cums but when he cums

Jack is fully into it now and is sucking Mr Fowler's cock for all he is worth. His hand pumps it while he bobs up and down. It is clear that he wants to make the older man cum.

Emily practically drools at the sight of her boyfriend so enthusiastically exploring his bi-side. This fascinates you too having only just figured out your own bi-side it is marvellous to be on this adventure with the macho Jack.

Mr Fowler grunts in acknowledgement to something his wife says, reaches out and grabs his male lover's short hair and starts jut his erection into his mouth. It is clear he is about to cum. Liz whispers something else and Mr Fowler mutters:

"Yes, take my cum James"

You look at Emily wide eyed - James was the name of his oldest son.

Is Mr Fowler imagining-

You don't have time to finish that thought, Liz glances at you with a Devilish look as her husband pumps his cum into Jack's mouth. It confirms, this is Mr Fowler fantasising about facefucking his son.
