Biker's Virgin Claim - Billionaire BDSM Age Gap Romance

It was a day like any other when Evelyn, a freelance painter, received a generous donation. Surprised and curious, she couldn't help but set out to find out who was her anonymous benefactor. Little did she suspect that he was a very famous local billionaire. His reason for the donation? While he didn't want to admit it to her when they first met, it was pretty obvious. He'd always thought that Evelyn was a stunning beauty who deserved more.
But Evelyn wasn't sure there could ever be anything between them. Alexander was much richer than her, almost living in another world. He was also much older and more experienced. There was no way he could ever have eyes for her, except that. he'd already been smitten by her sunny personality.  But Alexander also harbored a secret. His biker life was dangerous and he didn't want Evelyn to ever find out about it.
Still, secrets can never remain hidden forever and, one day, Evelyn will find out.
