From swimmer to OnlyFans creator Luana Alonso gets the chance to turn her fins into money makers… with a popular sex doll company sending her an offer to team up and sell replicas of her feet!!

TMZ Sports I received a letter from the people RealDoll …which details how the retired Paraguayan Olympian can rake in big bucks with her toes – while giving the foot lovers out there something to enjoy.

“At RealDoll, we pride ourselves on offering our customers unique, customized and lifelike creations that help them connect with their fans in a truly personal way,” the letter said. “Given your growing success, we believe there is an exciting opportunity for us to work together.”

“We want to offer you the opportunity to sculpt your feet from a lifelike, high-quality material that we then offer for sale to your fans.”

We're told these puppies would sell for $2,000 each – or both paws for $3,500 – and Alonso would get 20% of the sales. The offer also includes an option for her to sign the fake feet for an additional $500… and she could pocket all the extra coin.

The company says Luana could even share a link to purchase the product on her OF page… making it easy for her most dedicated followers to get their hands on it.

It explained that Alonso is the perfect candidate for a cast… and added: “While you may not have an Olympic medal hanging around your neck, we can all agree that your feet deserve a podium of their own!” have that rare combination of grace, strength and undeniable cuteness – talk about feet that know how to make a splash.”

Of course, Alonso caused a stir when she was supposedly there sent home from the Olympic Village for creating an “inappropriate atmosphere,” which she later denied.

She has since retired from the sport and now offers her content for $35 per month on the subscription-based site… but it's clear that RealDoll believes it can benefit even more from it.
