Clinger (2015)

(0:13) Jennifer LaPorte is lying on a pool mattess in her bikini. (0:35) Jennifer LaPorte is stripped down to her bra with a guy. We see brief panties too. Though we see her take them off to make love with her ghost boyfriend, when two people enter the bedroom we see her all alone with her bra AND her panties still on. (0:36) As they try again, Jennifer LaPorte takes her bra off but we only see her bare back. (0:37) After his head comes off, Jennifer LaPorte is sitting on the bed covered in blood and in her panties. (0:38) Jennifer LaPorte is in the shower washing the blood off but we only see down to just above her chest.
