Medically Assisted Sex - My Wife Jerking Off The Neighbor

About two years ago we had some neighbors move in with a paralyzed son. The son was in his early 20's. Anyways, long story short the mom is complaining to my wife one day about not having any licensed therapist in the area for her sons "medically assisted sex".

Eventually this lead to her approaching my wife and asking if she would masturbate him. Basically begging her to do it, as her son was sexually frustrated and couldn't do it himself.

My wife and I talked about it and finally agreed. Viewing it more as helping someone in need rather than sexual favors. All in all she said it wasn't even that awkward. That his penis was now really sensitive and it didn't take long.

For about a year she'd get a text every 2 or 6 weeks and she'd go do the deed for him. It was all pretty straight forward. Then one time the mom told my wife he had "something to ask you" when you get here.

The kid asked if my wife would get naked for him. She jerked him off like normal and said she'd have to talk to me about it. Again, long story short I agreed so the next time she got fully naked for the kid.

This lead to him asking to smell and taste her pussy and she's let him do so a few times. Actually sitting on top of his face letting him lick her before she jerks him off.

Now's he's asking to have sex with her, but my wife has flat out refused. Even telling him not to bring it up again or she'd stop coming over.

My confession is that I'm actually okay with it. All in all it's a bit awkward seeing the neighbors knowing my wife has been naked in their house jerking off their son, but I feel like the kid should at least get to enjoy some sex every once in awhile.
