Learning New Roles

I’m a married str8ish masculine man,no one would expect. but our sex life has been slow most of our marriage. and seems to be on the road to non existent.
I have become an on call cock sucker for one guy for over two years now.
It’s made me even more submissive.i actually love this role, I have another gay man that is very dominant and love tying me up and doing all kinds of things to my body.wow
And I have a third I suck off on a semi reg basis.
I meet yesterday with a very hung older dad.he’s married in a sexless marriage too.
He’s all top….
We meet out just to check things out after some steamy messages.
He is over 60 .and has a dominant side. 8” too.
He wants a sub bottom .and I want a dom top…
I hoping this works out. I feel the need to be a total bottom for a dad.
He told me I was his girl and my pussy would be his….
I am very turned on by serving a older hung dad type. He said I would be dressed in panties.but not for long. When I got into his truck he reach over and pinched my hard nipple….wow.hope we start soon
