My Sister and I for the First Time part 4

[This is the fourth and final installment in this series, taking place on Monday. I am sorry that this story took so long to write, but it is finally here. This is the culmination of the series up to this point, and it is true to the best of my abilities. I hope you enjoy it.] I woke up sticky, sweaty, smelly, sore, and smiling. Each of those could be directly traced to the beautiful young woman whose bed I was currently sharing. As I came fully awake, I noticed my sister had her hand wrapped around my cock and was pumping away. She saw my eyes open, or maybe heard the breath catch in my throat and looked up from her handiwork. I opened my mouth to speak, but her lips fell lightly fell across mine, stopping my words. Her hands rose up to my chest and she rolled her slight weight on top of me. Her hips rose, her knees fell and her hand trailed back down to my cock.

The feeling tossed me over the edge, and I joined her in climaxing.
