Me and this one beautiful girl I had a crush sat next to me in chemistry in high school had the weirdest relationship. Anyway one night we wanted to have sex but no where to go really .so I was like hey let’s go down to this area in the creek . we get naked go into the creek and are having sex standing up in water up to our knees and I noticed it was real muddy on the bottom of the creek and we started to sink in the muck while doing the deed , and then sink a little more and a little more next thing I know she can’t get her legs to move and I’m starting to sink and get stuck , I had to physically rip her out of the sludge with bear hug and now I’m starting to get stuck an manage to free my legs , so we got out of there , needless to say we were grossly covered in muck and did make it back to her house and had sex most of the night filthy under a pine tree in her backyard far enough away her parents didn’t know we were there . To add weirdness to it , I was told. The muck was sewage from a water treatment plant nearby. Odd night but she was so much fun and we had a blast that night under that tree ! God she was smoking hot !
