BBC instead of boyfriend in Reality Show Swing, more?

Pornstars have real sex in their personal lifes. But when they are hired as stunt cocks on a "reality" show, I bet they know exactly what to do (it's no doubt outlined in their contract).

Why else would the company behind a show employ pornstars to mingle with the "ordinary" couples?
 
talking from personnal experience huh ? ;)
