Skimpy red Thong and Suspenders

As I sit watching her reclining on the sofa with her beautiful bottom facing me, she bends her knee just enough to exaggerate the shape of her bottom and her tiny red thong. She knows where my finger has been sliding for the past ten minutes, and that she will get to suck on it before I slide it in her. I can see the perspiration rising in anticipation, on her inner thigh as I crawl towards the sofa.
