A parody sex tape featuring actors playing Kylie Jenner and Tyga hit the market the day Kylie turned 18.

Now porn companies are offering up huge bucks for the real thing.

Vivid, which made Kylie's older half-sister Kim Kardashian famous, will pay ten million for the couple to copulate on film.

"Kim's sex tape helped launch her career and would be nothing but positive for you," Vivid boss Steve Hirsch wrote in his offer.

Given all of Tyga's recent financial problems, we're thinking at least he's considering the offers.
