Blackmailed by boyfriends roommate

Date: 5/18/2018

I dreamt my boyfriend moved to a new shared house with two other guys (don’t know em). Things were going well and after he left for one day I fell asleep on the couch. Not long after, my boyfriends roommate, who I think his name was Ethan, woke me up with a hand on my neck telling me to be a good girl and stay quiet, he had a lot of pictures and vid of me that he threatened to send to the teachers college I was trying to apply to. I was too scared to do anything, and that made him grin, I remember vividly how terrifying that grin was. He started playing with my tits, rolling the nipples between his fingers, then shoved two fingers in my mouth to keep me quiet, ordering me to suck on them. He pet me , telling me I was his whenever my boyfriend left the house. Another day, just after my bf left, he came into my room with a massive ball gag (like almost as big as a tennis ball). I immediately spooked and climbed off the bed on opposite side of him, but there was no getting away cause he was by the only exit. He shoved me onto the bed and tried putting the ball gag in, I stopped him and told him to at least use my own much smaller ball gag. I pointed him to my toy and bondage drawers and he laughed, knowing now he had a kinky slut as he put it. He continued to shove his big gag in. Once the gag was in he wrapped a shock collar round my neck and started feeling me up, while I shook like a leaf. I remember getting shocked several times for not opening my legs and for jerking away. After playing with my body he eventually just started petting me again whispering how much of a good girl I was for Master (as he started calling himself. ) He then pulled the gag out to my relief, but it was short lived as he unzipped his pants to pull out his sizable cock, reminding me if I bite, I will live to regret it. He forced my head down into his lap, choking me and pushing his cock down into my throat. The dream was so intense that I woke up. Feeling odd now cause I kinda enjoyed it and feel like a fantasy has been fulfilled, but also guilty cause i liked it despite betraying my bf in the dream. Like I woke up extremely wet, not sure what that says about me .
