Blackmailing Bigfoot - Spice by Kelly Comans, #1

Life hasn't been kind to Kelsi lately. Her long-term boyfriend dumped her for someone younger, skinnier, and--according to him, anyway--prettier. She lost her promising career to the pandemic and estranged herself from her religious family. Dating has been... awful. Human men are just... AWFUL. Kelsi decides she needs a change of scenery; so, she uses her meager savings to buy a used RV and retreats to nature for an extended sabbatical.
Beginning to rediscover herself and learning to love her curvaceous body while sequestered in isolation--surrounded by only nature and not another human in sight--Kelsi is finally, for the first time in her life, experiencing peace and true happiness.  Eyann is a member of an alien species visiting Earth to study the elusive and endangered species known as 'humans'. He's under strict orders to remain hidden and not allow himself to be seen by the primitive creatures.
In the past, others had been less careful and the humans are already suspicious to the existence of Eyann's people, The Yetis. Known by many names to the humans--Sasquatch, Bigfoot, Ape Man, Swamp Ape, the Wood Booger--more and more the humans are catching on to the Yetis' existence. His discretion is more vital now than ever as the human species and all of Earth teeters on the brink of destruction.  But, there's something special about the human female he's just spotted, completely alone and quite far from the rest of her civilization.
He can't help himself as he watches her sunbathing from behind a tree. He cannot tear his eyes from her as he inches closer, captivated by her thickness, her vivaciousness. He's never seen a human with so little clothing covering her body... Kelsi is BEYOND fed up with human men... But, when she spots the hulking, enormous, hairy, muscular form peeking out at her, she can't help but be intrigued...
and a bit horny... It's been SO long since her needs were met, after all...  So, with the iPhone that never leaves her hands, she snaps a perfect picture of him. Of Bigfoot! Proof, at last! Eyann has been waiting his entire life for an encounter like this. Humans have fascinated him since cub-hood, on a level he's never quite understood... But, he knows if she shares that photograph with other humans, his career and life's work will go up in flames.  He'd do anything to get her to delete that photo... Eyann awakens something PRIMAL, BEASTIAL within Kelsi...
She promises to erase the photo--on the condition that he answer all her questions... and satisfy her every desire...
