GF & I began this a year+ back.
She had a guy her age (she's a gorgeous 45yo blonde, I'm 20+ years older) she picked him up at a pub and she began seeing him for sex.
It seems not only is he good & long lasting, but he very well endowed. About 8.5 inches & very thick, she says.
He works in medicine and is required to have his blood checked monthly.
My GF would regularly go to his place for a good fucking or 2.
1 nite she came home with her panties positively dripping her bulls semen. She told me he had very large orgasms, as she slipped her panties off.
She told me to take a look at her pussy and it was covered with his semen. Then she told me if I wanted sloppy seconds, l had to lick her pussy clean. I really didn't want to do it but she was insisting and she pointed out that I had an erection. At last I gave in and licked her pussy clean. And I've been doing ever since.
But at least I get the very sloppy seconds.
