I part them a little, and tease her clit with my index finger, up and over and around and around. After a minute, she shudders and quietly cries into ...y shoulder as her muscles quiver and tense. Waves of pleasure course through her, and then she goes still. Her eyes close for a minute, but then she resumes rubbing against me. Her underwear and my jeans are discarded, and she slides her bare vulva against my boxers. I’m so hard it hurts, and my precum is soaking through the cloth. I push down.

It was so tough not to grab my stiff dick and give it a good pulling before going to school. I walked the mile to school and with every movement parts of me.
