Just a bit of background info. Ashley and I are both university students studying physics. In the past, we admitted to each other, that we like each other, but we didn’t want to be in a committed relationship, so we turned to being FWB.
She has long black hair that extends till around the height of her breasts, cute face, a little less than 5.5 feet tall, has slightly perky breasts and decently sized ass, with a slim waist. She’s the kind of girl that looks shy and reserved but is really horny on the inside.
This story continues from my previous shower sex story. After we had shower sex, a few hours passed while we were studying analytical mechanics. I don’t know why, but I was very horny that day. I had already filled her up with loads of cum earlier during our shower sex. I remembered there was one time I fucked her while we were studying electromagnetism at this exact table (story’s in my posts if you’re interested), I needed more of that pussy. I got up from my chair and walked over to the space behind the chair she was sitting on. I whispered in her ear, interrupting her while she was scribbling some equations of motion on her paper.
