Los Angeles, California - Wow, what a sight! Kourtney Kardashian shows off on Instagram how sexy a micro-bikini can be, and her fans can't get enough.

Reality TV star Kim Kardashian's big sister Kourtney (41) loves to pose in hot outfits on her Instagram channel, but she's stepping it up a notch with her latest bikini pics.

In the photos, the mother of three is seen standing in a swimming pool in an itsy-bitsy, bright red, two-piece swimsuit.

Her top consists of so little fabric and is laced so tightly around her body that a good portion of her breasts are still visible.

She posted three photos of herself in the seductive outfit, but the third picture in the photo series doesn't show her face anymore, just her well-toned body in the red bikini. She's obviously perfectly aware how fantastic she looks.

Her fans also seem enthusiastic about the images: just 17 hours after their publication, the sexy shots of Kourtney Kardashian have already received three million likes!

The 41-year-old's Instagram channel has a whopping 109 million followers. By comparison, Kim Kardashian has 202 million subscribers.

Kourtney's red bikini definitely made a splash. Her Instagram posts typically receives between one and two million likes.
