Kayla Simmons strips down to barely there bikini in bed as fans say “good grief.”

FANS showered Kayla Simmons with praise for a bikini photo on a bed that she called “rainy days.”

'Good grief,' said one fan' and 'insanely beautiful', claimed another as the ex-volleyball star sat dreamily on a duvet.

The social media sensation had plenty to think about as she stared thoughtfully around a bedroom.

She just completed a travel vlog after jet-setting to Geneva, Paris, Nice, Tokyo and Hawaii.

And she also paraded some revealing angles in swimsuit selfies.

Kayla has never looked back, nor been shy, since giving up any chance of a volleyball career in favor of online fame.

And many fans seemed out of breath – or in need of a nap – after seeing her latest photo in the middle of a bed.

One follower demanded that the prestigious magazine Sports Illustrated take an interest in her.

“SI cover model if I ever saw one,” he insisted.

“Wow, Kayla Simmmons looks amazing in this bikini,” gasped a second admirer.

“Perfection” and “Yum” were other sayings.

And congratulations if you got any of these in Compliment Bingo: “Beautiful”… “Hottie”… “Unreal”… and, a new twist on an old favorite, “Wowza!! Unreal.”
