"Just for that," Hector slapped Cassie's bare bottom, causing her to twerk against him."You want this? You want to fuck me now, your own twin sister, ...n a public restroom while others might be waiting with full bladders and growing tempers? Let's do it, Bro. Let's fuck right here!" Cassie invited him to his surprise, bending over the sink with her ass showing now and her lacy silk panties down."Don't you mean 'make love, ' Sis?" Hector kept up the teasing as he prepared Cassie with his. "Holy fuck!," he said, as a book hit him in the head.? "Baby, I've gotto get your number."I soaked up the moisture as best I could with my panties, then tossedthem to him."A souvenir," I said."Can I see you again?" he asked."When I need you, I'll come see you," I replied as I tucked my top inand straightened my tits. Then I kissed him on the cheek and left adazed young man behind.As I approached the Kappa house, I saw Kristen returning from a classwith books in her hand.? She saw me, and broke. Perhaps there was a hidden switch? Not abook? He looked at the bookshelf again. On one bookend, a human skulllooked back.Alas, poor Stanley, it seemed to say. He smirked and picked it up -- ortried to, for after rising an inch it rose no further -- and at the topof that inch he felt something within the shelf click -- and the middlethird of the bookshelf seemed to become weightless as it receded a fewinches backwards into the wall. Stanley pushed the middle section of thebookshelf and it rolled. We arranged to have her come to my place one evening and go thru the albums on a day that he was working so that she would be assured they would not run into each other.I guess we picked a really bad night as it was raining horribly. I greeted her at the door and helped her out of her rain coat and gave her a towel to dry off her hair. She removed her wet shoes and dried off her feet. She was wearing a pair of cut-off jean shorts and a sleeveless shirt cutoff just below what obviously braless.
