My girlfriend has been wanting to have a threesome for a while with another guy. I'm pansexual and she has this fantasy of watching me get fucked by another guy. I didn't want to do that. I've never actually ever had sex with a guy. Just hand jobs and blow jobs. I just told he no and it was weird to me. I've been saying no about this for months. We celebrated my 21 birthday Saturday and there was a shit ton of drinking. I got completely shit faced. My girlfriend couldn't drink because she's on medication so she was pretty bored. I blacked out and in the morning I start throwing up. I was in pain and had a headache. My girlfriend told me she wanted to show me something. She said we made a sex tape but I don't remember making a sex tape. By sex tape she just recorded on her phone of me having sex with one of her guy friends. I was passed the fuck out on the bed and her friend was fucking me. They were both laughing in the video and I'm upset because wtf. I told her I didn't want to do that. She thought it was funny that she finally got to live out her fantasy on my birthday but I'm hurt we would set something like that up knowing I didn't want to do it....
