Katelyn Runck Shows Off Toned Abs, Cheeky Assets & Considerable Cleavage In Sultry Spread

World Beauty Fitness & Fashion (WBFF) star and model Katelyn Runck continued to be active on her Instagram account on Sunday, October 18 with an inviting new share. In the two-picture update, the 29-year-old teased her 2.3 million followers by posing provocatively in a tiny all-black two-piece swim ensemble that allowed for a prominent display of her gym-honed abdominal muscles, as well as her considerable cleavage and cheeky assets.

Runck referred to her "body of work" in the accompanying caption, which seemingly served as a call-to-arms for her admirers, who subsequently flooded the comments sections with words of wonderment and declarations of love. Within an hour of going live, the model's update had racked up nearly 500 replies.

"OMG, your abs are amazing," wrote one fan. "Well every bit of you is amazing."

"So beautiful and so damn sexy," gushed a second devotee. "You have an amazing body."

"You definitely have built a masterpiece," added a third admirer of Runck's chiseled physique.

"Smokin hot in your sexy black bikini," opined another enamored follower.

The first photo in the slideshow found Runck posing under the roof of a beachfront cabana, with white sands and palm fronds visible in the background. However, her surroundings were largely out of focus as the camera locked in on the statuesque beauty. With one hand resting on a plank beside her and the other grasping at the straps of her skimpy bottom, Runck parted her pouty lips and fired a seductive gaze to her right.

The garment covered little beyond her most intimate areas, and her scanty top was similarly revealing, as it featured a series of thin, crisscrossing straps between her breasts. As a result, her cleavage was very much on show.

In the next snap, Runck surprised her followers with a rare, rearview shot in which her bottom piece was revealed to be a thong. Consequently, her taut posterior remained the picture's focal point. As the picture was taken, Runck cocked her hips slightly to one side, accentuating her sinuous figure.

She was snapped from a wider angle in the second shot, which allowed for an impressive view of her sculpted thighs and muscle-bound calves in addition to the aforementioned curves.

Runck's post has already made a significant impact as of this writing, racking up 15,000-plus likes.

Just one day before enthralling fans with her black bikini, she sizzled in an update while sporting a powder blue set.
