Rachel was basking in the after glow of yet another orgasm that day and they only seemed to get better as Rachel found better and more inventive ways to pleasure her cock. Rachel started as she heard Jasmine call out from the doorway, "Hey what's taking so long?"
Rachel quickly stood up and noticed her cock stuck out from the bottom of her skirt and shrunk it back to 12 inches so that it would again be hidden. She did all this while saying, "Sorry its that time of the month you know."
"Oh, right OK."
After lunch was over the two friends found themselves at their least favorite class history. Taught by the worlds most boring teacher, Mr. Brown. He could drone on for hours about important people and events and such in his monotone voice oblivious to the comatose students he was talking to.
Rachel and Jasmine always sat in the back row Jasmine in the corner Rachel in the desk right next to it. Today they happened to be the only ones in the back, an oddity in itself, but nice all the same. As the class started Rachel almost immediately tuned out and her mind quickly turned to all her sexual escapades earlier that day. Unknown to her the ring started to slowly lengthen her cock.
Jasmine was trying to pay attention but was losing only a few minutes in and as such her gaze wandered. Something right below Rachel's seat caught her attention and she tried to determine what she was seeing but it was hard to see because most of it seemed to be blocked by Rachel.
Rachel's cock was slowly reaching 16 inches and Rachel was still in la la land. Jasmine was shocked when she finally saw what it was below Rachel's chair. She could clearly see the head of a cock and a few inches of the shaft, and it seemed to be getting even longer! Jasmine could only assume her long time best friend had a huge cock and was having an erection in class. She couldn't take her eyes off it, the cock was easily the largest she had ever seen was getting even larger. Jasmine longed to see just how big it would get.
Rachel finally came to near the end of class and realized her cock was so big that it was laying on the floor around 2 feet 6 inches long and she quickly shrunk it back to 12 inches. She hoped that Jasmine hadn't seen it but as she looked over Jasmine was taking notes and looked over just then and smiled at her like usual. After class Jasmine didn't act or say anything that seemed out of the ordinary so Rachel assumed she was in the clear. She was relieved because Jasmine was coming over that night to swap notes for this very class, Jasmine always fared better in that class than Rachel, and she didn't want any awkward conversations later. Jasmine on the other hand had her mind in over drive making plans for that night.
