'I trust Emily and thought this would be kind of fun,' Lena said. 'Girls share their sexual stories with each other, friends tell each other everything.
'Emily's seen pictures of Adam's d***, she knows all about our sex life I tell her everything. Now I don't have to tell her, she can just try his penis.'
The clip has now been viewed nearly seven million times and has sparked a huge debate online, with commenters branding their actions 'sad'.
Lena and Emily admit they've had a threesome together before and say they want to 'share' Adam's penis in the X-rated and expletive-laden clip.
