I had a late dinner following a couple afternoon meetings, and I went back to the room to clean up. I showered, and slipped into a slinky black dress ...ith spaghetti straps, no bra, and a black thong. The neck was cut low, showing off some nice cleavage, and the heels I put on help to accentuate my calfs.The hotel was not in a major downtown area, and without any real night spots close by, I settled for the hotel bar. It was a typical hotel spot, not real hip, and, on a Monday night, not very. I asked her if she wanted me to be hard. She wasquite for a minute and then said “yes she liked it.” My dick was so hard withher laying right on it. We spent the next hour or so laying in the sameposition in total silence. After the movie she got up and went to her room. I got back to my bedroom as fast as I could. I dropped mypants as soon as the door shut. I sat down on the corner of the bed with mydick in my hand stroking it furiously. I thought about how my sister was socasually rubbing. After early retirement I spend most of my time in the study of my corner house. It offers a view of a few trees and one bedroom window of the first house in the side street, from which only my study window is visible, apart from those trees. Reflecting on the power of math instruction I developed the habit to stare at the tasty teen blonde beauty there, as soon as she came back from school. Ever since I started to stare at her, the good girl developed the habit to do first her homework, smiling. She took two aspirin as her phone buzzed.“Wake up your son with a kiss,” the message read.Fuck. She thought. She used to kiss him more when he was little but had stopped after catching him looking at her differently. She better just get it over with.When she entered the room she caught a whiff of something she vaguely recognized. It wasn’t until she saw the white cloth near the bed that she realized what it was. Jon had been masturbating.She shouldn’t be surprised after how last night went..
