Five photos with different poses were all it took to send Rachel Cook’s fans into a frenzy in her late September post. Cook wore a tiny multicolored bikini with knitted finishing along the edges of the micro triangle cups and the front of the stringy bottoms.
The details of the bikini weren’t revealed until the final slide, where she raised her brown, sheer knitted cover-up dress. One user wrote, “Wow, I thought I liked the brown pullover until you revealed the chewy goodness under.”

The 900+ comments on the post were mostly positive. One fan begged, “Have mercy.” A second user wrote, “This look can stop a man dead in his tracks, so majestic.”
Many comments focused on her cheeky poses, particularly in the opening frame where she posed sideways, pulling the cover-up just high enough to expose part of her bottom. “The sweetest bootie on the internet,” one fan declared. Another echoed the sentiment, “Best as- in the world.”

Someone responded in the comments, “I didn’t see you there when I visited the Blue Lagoon.” Another smitten fan replied, “I’ll meet you where you want. Sahara, North Pole, jungle.”
The slides featured close-ups of Cook’s red bikini top and her body half-submerged in the blue waters, putting her chest front and center. “Beautiful cleavage,” one admirer commented simply.

In the sultry video post, Cook turned around, tugging the short cover-up down to tease fans and show off her highly requested back view. The comments again were filled with compliments, describing the model as “perfect.”

Still in October, Rachel Cook switched things up with a retro-inspired schoolgirl aesthetic that was just as provocative as her beach looks.
She wore a cropped black knitted vest over a short-sleeved white crop top, paired with a pleated black micro-mini skirt. Cook completed the outfit with sheer white thigh-high stockings and chunky loafers.
She posed on a wooden piano bench in a dimly lit room, with her hair in pigtails for a sense of innocence that contrasted with her sultry gaze and outfit. She captioned the post, "Piano lessons for beginners. U in?” The comments section was filled with a chorus of eager yeses.
