Twin sticks her fingers inside her pregnant sister’s cervix because ‘our vaginas are basically the same’

When it comes to Extreme Sisters, we thought we’d seen it all. But a preview clip of twins Christina and Jessica has reached new heights of disturbing.

The TLC programme follows the lives of sisters who are so close that some even poop together, whilst others share toothbrushes – but these 39-year-old sisters get to know know each other’s bodies really, really well.

Christina, who is pregnant with her third child, asks her sister to do what they did when she was pregnant, and check her cervix… with her fingers… at home.

‘When Jessica was pregnant, I checked her cervix, so I feel confident having her do the same thing for me,’ Christina tells the camera, although Jessica adds that she’s ‘never’ checked a cervix before but has ‘looked online’.

‘You stick your fingers in there, you start opening them up and then the wider they go, your cervix is open,’ she explains.

Christina is adamant she wants her sister to ‘stick her fingers inside of [her]’ than a ‘random stranger’, a nurse.

‘You have the same DNA as me, my vagina is basically your vagina anyway,’ she says.

They then set up their ‘nursing station’ with pillows on the bed, while Jessica offers to shave Christina’s vagina.

‘It’s cool, because it’s like I get to see inside my vagina,’ Jessica says before the procedure starts.

As Christina lies on the bed, Jessica puts some gloves on while giggling before inserting her fingers.

‘It looks like my vagina… a vagina is a vagina,’ she says.

The pair are giggling throughout, with Jessica urging Christina to ‘relax your vagina’, before she concludes: ‘Oh my god you’re so soft in there’.

As you can imagine, viewers are pretty shocked by the scenes, and disgusted.

‘You know what I’m soooooo done,’ one wrote, with another adding: ‘This is disturbing’.

Another slammed: ‘Ummmm besides the obvious, this isn’t ok to just randomly be checking a cervix, at home, with a glove that you just pulled out from under the kitchen sink?!?’

Someone else echoed: ‘Ok so sure you’d rather have someone who googles how to check a cervix than a trained professional but ok’.

‘Oh, no, no, no, no, no, no! Wrong on so many levels and they televised this too,’ a fourth wrote.

Extreme Sisters airs Mondays on TLC in America.
