Late 50s and very conservative. Normal as can be.
We have a guy friend we get with pretty regularly.
My wife turns into a sex machine. We take turns with her and sometimes it's like she can't get enough.
Always 2 rounds with me and 3 with him, there's been nights it's more. She's horny as fuck for days after so we have a lot of sex.
You'd never think this about us if you met us.
