I'm always in the corner of class and my only good point is that I'm serious. One day, due to a seating arrangement, a naughty gal ends up sitting behind me... I end up helping her study and as a thank you she does all sorts of things for me but she also starts doing naughty things... Eventually she shows me her boobs and things escalate and we end up having sex... From then on, the two of us do all sorts of naughty things at school! *This is a lovey-dovey big-breasted gal story.
