Caught While Stroking My Cock

This morning I woke up with a hard on that wasn't going to go down unless I took matters in my own hands. So I sat up in my bed and start stroking my cock, when all a sudden my front door opens and there stands my ex -sister-in-law with a blank look on her face. I say hi and keep on stroking.

She just stands there staring at my cock and licks her lips and asked where her sister is (we broke up Monday). She says ok I better leave. I ask her why as I was almost done so she sits down on the bed beside me and watches me as I cum. She gets up to leave and says she will be back another day. I said ok and that I would wait but that she was going to have to join me next time. She winks and then leaves. I can't wait!
