Mean time, sister took bath and was coming out of bathroom. She was wearing a towel over her body and holding her inner briefs washed. Unexpectedly, t...he towel slipped down and I became mad seeing her naked and cleanly shaven pussy. She in a shy dropped what ever in her hand and rushed to bedroom. I took out her bra and inner brief lying on the ground. By the time she came out of her bed room and collected her bra and inner brief. Her face has become red. I was nervous and went to hall taking. Thats why I was shocked but a little pleased when a new girl in my economics class sat right next to me and chatted me up almost immediately. Her name was Ashley, a really basic name for a really...authentic girl. Id say her last name to give her more identity but I honestly dont even know it. “Hey, Im Ashley, Im new here” Ashley announced to me, giggling in high-pitched but still laid back voice.”Yeah i know that, Mr. Roth literally just introduced you to the class” I responded, laughing. I. When she first explored a small area of the roof that the cafe had an access to, the water tub was a mess, a bit like a forgotten swimming pool or a fish tank of a careless teenager. She spent a month's worth of evenings to clean it up, seal and paint it afresh. She changed the water there monthly and kept it covered up for the most of the year. She even helped to kickstart a small company promising to develop a solar powered pool heating system. Right at that moment, being freshly energised. If she couldn't go somewhere with me, in which case we fooled around in classic style in my car, she'd wait until everyone was asleep and come see me for some one on one, personal instruction.The exception was if the boys and her mother were gone at the same time. Any time that happened, she called me and either had me come over, or came to my house. Technically, she could have come to my house after school any time she wanted to, but she never broke the rules like that.I took things very.
