Kim Kardashian: Very Responsive in Threesome, Porn Star Alleges

Kim Kardashian posing for bikini picture after bikini picture? Not surprising.

Kim Kardashian engaging in a threesome with a male porn star and a female porn star? Okay, not all that surprising either.

That's exactly what Julian St. Jox says happened in 2001, as the adult film actor - known for such movies as 5 on 1 and Afro-Centrix 17: Butts Up - tells Star Magazine he and fellow porn star Emily Ann got it on with Kim at a swingers party over a decade ago.

According to St. Jox, the ménage à trois took place at the Wyndham hotel in Culver City and followed the unexpected arrival of a then-scarcely known Kardashian, who turned heads in a miniskirt and tank top.

"As soon as Kim walked in, everyone was looking," St. Jox tells Star. "She wasn’t known at the time at all, not like today, but for everyone who frequented these parties, she was interesting because she was a new face."

So, what happened from there?

St. Jox says Kim and her date - she was married to Damon Thomas at the time, but his presence at the event remains unconfirmed - ended up in a private room with Emily Ann. The two women started in on some intercourse and St. Jox eventually joined in.

How did it go?

“She was a little submissive, but she was good,” says the actor. “She knew what she was doing. She was very responsive to me... [and] looked like she was enjoying herself very much."

We all know what that looks like, don't we, Kim Kardashian Superstar fans?
