Getting It Back. I Hope.

My neighbours Angela and John are in their fifties.
Angela's very good looking and an extremely highly sexed woman who just so happens to enjoy lots of younger cock.
I'm twenty six and have over the last eight months been obliging her with my dick almost every day.
John is what you'd call a workaholic. Someone who cannot stay at home and twiddle his thumbs. He's also a man who's lost his libido.
However until recently he didn't know I was fucking his wife.

During an especially horny afternoon five weeks ago fucking Angela's cute arsehole, John walked in.
It could have, in my opinion, gone drastically wrong for me, as John is not someone you would want to fight.
However smiling at us both, he said "Well don't stop, keep fucking her".
A little nervously I did as he said with John walking into their kitchen. Angela kept telling me to fuck her deeper, so I kind of recognised this was probably not the first time John had seen his wife being fucked by another man.
And I was right.

I now know since John lost his mojo Angela has had over thirty younger men fuck her. John from what they've told me, used to join in, but he just isn't interested in sex anymore.
So these past five weeks I've fucked Angela several times with John present. And only a few days ago he actually got an erection watching us fuck.
Angela later told me it's the first real hard on he'd had in years and that sunny afternoon it was my turn to watch as John fucked his wife from behind.
I'm going round tonight to have sex with Angela and John will be there. They've both asked me if I would mind if John gets involved.
I've said of course I don't mind. Now I hope he gets horny enough again to fuck Angela as I think it's given them both a huge sexual and marital boost.
