By the time she came to bed she was in a good mood but exhausted from studying. She asked, sheepishly, if it could be a "quickie".

Of course, I said.

Quick hand action on both parts. A bit of sucking with some nice firm fingernails on my ass (I always want more from her in that regard). Some cowgirl followed.

Eventually, at my request, she mounted me and I jacked off with her wet pussy against my face.
