They are not Jess's tits that are shown - it is a body double. You never see her face and her tits in the same shot. And no sign at all of her arse or her cunt.
Wow that last shot really the me for a loop. The wet, sloppy smashing sounds were sooo outta place... It woulda been unsettling in an it 80s mudwrestling fuck-fight! But...... It's just rain... At the best\worst time lol
