Riding Bareback (Bareback Cowboy Erotica)
Gwendolyn Wilde

But the rugged, handsome farm hand Ben doesn't want to get caught naked with Cassie. He'd lose his job. However, Cassie is determined to seduce him, and Ben finds her so irresistible that he soon forgets about the consequences.
But Ben soon learns that there's something else Cassie finds exciting. She wants it rough, and bareback...and she finds the risk of getting pregnant thrilling.
