Netflix show includes some serious pillow action.Viewers of the streamer’s steamy new series “Obsession” have been left mortified by an X-rated scene showing a character humping a pillow.The frisky four-part drama, released last week, revolves around William (Richard Armitage), a successful London surgeon who embarks on a sordid affair with his son’s fiancée, Anna (Charlie Murphy).In the second episode, William follows Anna to Paris and checks into a hotel room that she has just checked out of.Anna’s scent on the hotel bedsheets proves too much for William to bear, with the horny surgeon seen writhing up against one of the pillows before sniffing it as he furiously masturbates.“I’ll be bringing my own pillow and sheets next time I stay at a hotel,” one horrified viewer remarked on Twitter after watching William’s pillow pounding.“F–king hell was not expecting the pillow-sniffing w–k,” another viewer bluntly posted, seemingly stunned by the scene. Others took to Twitter to hit out at the scheming surgeon for sleeping with his soon-to-be daughter-in-law.
