A YouTube star took banter to the next level by duping his best friend into thinking he was in the middle of a steamy sex session with his sister.

Joel Morris, known by his online gaming name JMX, published a video of him pranking his pal.

The 18-year-old explains at the beginning of the clip that he is going to pretend to have sex with fellow Vlogger MaxPlays’s sister.

Another friend – Josh – then texts Max to tell him that Joel is in bed with his sister.

Joel then sets up cameras on the bed before the pair get under the sheets in position.

Predictably, his friend storms into the room screaming: “Get out of bed Joel, get out of bed.

“You’re actually a scumbag, you’re actually a f***ing scumbag.
