Last Night CFNM

Now this is something that does not happen to often.  I'm sitting at my computer which is in the living room watching some porn and doing what guys usually do when watching porn.  It's about 11:30 pm and there is a knock at my door.  I figured it was my friend from across the hall so I said "come on in it's open".  To my surprise it was a young lady from across the street.  There I am with a woody in my hand and a couple of guys fucking on my computer screen.  She totally acted like nothing odd was going on so I just continue stroking.  She looked at my screen and commented that it was very hot.  She then said "well I just stopped by to say Hi, my boyfriend is waiting and I gotta go".  She left and I shot a load that hit my chin.  I really wish I had turned on my cam.
