She came closer and tried to rest her head on my shoulder. I told her I could hug or kiss her only when she studies nicely. In reply she said she woul... make extra effort to her studies. She was more interested for a kiss, a tongue kiss. She took out her tongue and wanted me to join mine, I did that pretending I was bit skeptical. I took out her pull over and tshirt.
