Boyfriend's Father Is Very Good In The Bedroom

Dear NastyGist.Com , I know that this is not something that many ladies
want to talk about even though they are in the same situation but am
matured, I no my left from my right and I want your readers to see
things from my own point of view. My story is brief and straight to
the point:
I'm a 38yr old lady who is independent but I regret not getting
married in my mid and late 20s when men were in serious demand for
my hand in marriage. I kept saying I was not ready and now I blame
myself for all the shit I'm facing after I turned 33 five years ago. But I
met this young guy, he's 30yr old. I love him and I told him my real
age and he's ok with it, maybe because I spend my money on him.
Fast forward to last December, I met his father and one thing led to
another and the man passed a night in my apartment. It was very
hot! He performed far better than his son in bed...
My boyfriend's father is 57, divorced and he is madly in love with me.
He even give me money to increase my biz not like his son who
collects from me. The man is ready to marry me but my problem is
that I've slept with his son and I still do it with him once in a while
just to satisfy him so he doesn't suspect his father.
But I can't continue to sleep with father and son. I'm enjoying the
father's "juice" more. Pls what can I do?
