My freshman year about 2 months in, I didn't know many people yet and was just starting to make connections to hookup. At a floor party, I ended up going back to my room with a girl, we were both a bit drunk but that didn't stop us from fucking like crazed wombats. Turns out she liked big dick, deep and hard and had orgasms like tsunamis. After a couple sweaty bed shaking sessions we succumbed to the bottle of vodka we brought back and passed out.
Saturday morning at like 11 am I had a painful awakening *and* a throbbing morning wood. I stirred the girl awake and started to get busy when I realized...she wasn't the one I went to bed with. Full luscious hair, perky tits with pencil eraser nipples, and based on how she went after my shaft once awakened, not unfamiliar with sex...or me. But hey, I was engorged and she was willing. After a good rip-roaring session of sex ending with my glazing her cervix with cum, she went on her way...and I never knew her name *or* the name of girl I went to bed with the night before.
I didn't know it then, but that pretty much set the tone for the next 4 years.
