Peek-A-Boo

In my Engineering Drawing class a young 18 maybe 19 yo girl sat next to me. She's cute ... nothing special ... sorry sweetie, I've seen some good ones in my time. Anyway, after about an hour of drawing I got up to hand in my work. Out of habit, my eyes lingered to her bootie ... and bamm ... thong, thong, th-thong thong thong!!!! There it was ... red, bright and tuggin' dat ass. Immediately I felt dirty! And it was great!!
