The grandmother...

[Magineer]

... is, of course, the Helen Mirren type. Of course.

And Johnny has been coming to his grandparents' place for years as a special Friday night sleepover treat. His parents have probably been using it as free 'childminding' for the purpose of an evening off and their own sexual plans.

Yes, Friday nights have a kind of historical inertia behind them.

Things proceed as per normal until late evening but Granny and Granddad know they can't order him off to bed as they used to. The pair retire to bed around 11, leaving Johnny watching sport on TV.

In bed, Granddad reads ten minutes of his book and then switches off his bedside light, immediately turning away from his wife to sleep. Granny sighs and, putting down her own book, she allows her mind to drift back to the far off days when they had regular sex. This inevitably leads to thoughts of his one night stand, forgiven but not avenged as she had always intended to someday - yet somehow sidestepped. She begins to think of a male celebrity she admires and her hand strays between her thighs. She works herself up to quite a pitch, trying all the time to make as little movement and noise as possible next to her snoring husband... and this effort is probably what produces a catch in the throat. She needs water and has to go downstairs...

... where she finds Johnny watching a blue movie rather than the sports channel... his eyes glued to the action and his hand pumping his stiffly erect member.

From where...

The usual setup sees Sonny's mom Mavis and grandma Gilda both having been wild gals who gave birth at 15 (reported, not described). Now Sonny has reached 18; Mavis is a tennis-toned 33-yo MILF, and Gilda at 48 is a GILFy competitive athlete or whatever. Maybe Mavis and Gilda have shared young studs before. But buff swimmer Sonny is just too divinely gorgeous for them to ignore. Who entices him first?

"Child minding"? Little Johnny has to be 18 at the youngest, not a child.

You have correctly identified that the word was in speech marks and thereby signifying (to the brain dead, for example) that the word 'child' was not intended to be taken literally.

Thank you for your valiant efforts in calling the attention of all similarly challenged folk to this patently obvious fact. They probably do need it to be in their faces and in throbbing neon to actually take it in...
