Hector Penate: Shawn Southwick & I Had Sex In Larry King's Bed

Larry King's wife has denied an affair with their son's baseball coach Hector Penate, but Hector has gone on the record about their relationship — and included steamy details to boot.

"We had sex in Larry's bed -- a lot. I felt like it was my house," Penate told In Touch about his relationship with King's wife Shawn Southwick.

Penate adds that he believes King — who he describes as a "[sex] freak" — knew about the affair, but that he didn't care because he was engrossed in his own affair with Southwick's sister, Shannon Engemann.

"I still think to this day that Larry is in love with Shawn's sister," he told In Touch.

Penate said he started sleeping with Southwick two-and-a-half weeks after they met, when he was working with the boys on their baseball game and Southwick "made a couple of hints to me that she was ready to go."

Penate says that Southwick paid for his rent, bought him a BMW 7 series, took him on vacation to Cabo with the kids, and even wanted to have a child with him.

"She wanted to have a little girl with me," he told In Touch. "She was trying to fertilize her eggs to do that."

Southwick also duped King into co-signing Penate's apartment lease.

"She controlled him," he told In Touch. "He just sat there and signed it."

King has also been accused of lavishing sister-in-law Shannon with expensive gifts and putting her up in an expensive Beverly Hills hotel.

King and Southwick filed for divorce last week but are now putting their divorce on hold while they reportedly consider counseling and figure out their relationship.

In Touch's full, exclusive interview with Penate appears in the magazine, which hits newsstands Friday.
