Helen doesn't notice, whilst Clair doesn't stop

Clair's hand slid back and forth on Joe's cock, her delicate grip feeling the throbbing shaft lurch as her whispered words reached his ears.

"I think you want to go over there and bend Helen over that table. Stuff this big, hard cock into her hot little cunt whilst I watch. Fuck her from behind, pinned down on the table, until you feel her juices dripping between you and you empty that sticky load of cum deep inside her."

Joe's gaze remained locked on the oblivious Helen, her tits still tantalisingly outlined, whilst Clair jerked him. Within moments he couldn't stand it and his fingers grasped spasmodically onto the worktop edge as his balls emptied into his wife's hand. His teeth clenched, just a soft grunt to be heard as his meat spewed it's load into Clairs hand.

Turning away, Joe retied his dressing gown whilst Clair cleaned her hand off. He busied himself making breakfast whilst his breathing steadied. As Clair went to sit with Helen, Joe heard them discussing their plans for the day.
