I wake up at the frat house

I felt a tremendous pain in my body and a stabbing throbbing headache as I try to both open my eyes then shut them to keep the light out that’s streaming through the upstairs window... where am I? What happened to me? I’m completely naked except for my torn red panties that are dangling off my ankle... I am so super sore and I can feel dried cum around my pussy and ass and taste it on my lips... as I sit up in bed I notice that my hair is a wreck and the cum taste I notice in my mouth is Likely from the cum drying on my face... I turn around and notice my ass is red and has a distinctive handprint as well as several well placed raised red belt marks across it... what happened to me? I have no memories but was about to be refreshed when the senior from last night walked in threw me a towel and said man what a lot of fun you were last night but you should freshen your self up you reak of sex and stale cum... I was horrified as I gathered my skirt and top and went to take a shower...
