The air conditioning doesn't work in my apartment, so I usually sleep with nothing on except a thin sheet over my body.  I run a fan in my room to circulate the air.  It feels great when it passes over my nearly naked body.  I leave the window open to help vent the room and get the temperature to drop when it gets cooler outside.  This lets in a lot of noise, so I've learned to be a deep sleeper.

I work as a reporter for the morning news, so I don't have the luxury of waiting for it to cool off outside before I slide into bed.  I went to bed just before nine so I could get up by 3:30.  I drifted off to sleep to the sound of the fan purring on the nightstand.

I thought I must be dreaming when I felt a rush of hot air against my crotch.  But then I awoke from my sleep when I felt pressure against my clit from the sheet that covered me.  I looked up and saw Harley, my neighbor's Rotweiller, leaning against my bed with his head between my legs.  He had climbed in through my window since the screen was missing.

Harley licked again before I could react and this sent a wave of pleasure through my spine.  His rough tongue felt good even through the sheet.  At first I thought I should push him away and send him home, but he licked again with enough force to push into my moist entrance.  I couldn't believe how wonderful it felt.

I pulled the sheet up from over my feet and allowed Harley more access.  He licked again tasting more of me.  I could tell he liked my taste because he started licking deeper and faster.  I felt bad for enjoying it, but it felt so good I didn't want to stop.

I could feel Harley's tongue entering my hole deeper and deeper.  Coming across my clit each time sent me over the edge in just a few minutes.  I was cumming like I hadn't cum before.  Harley knew something was happening because he started licking faster trying to get each drop of fluid from my hole.  I had had multiple orgasms before, but none had ever happened this fast and this close together.

Before long, I had to take a break.  Harley had been licking me so fast it started to tickle and I couldn't take it anymore.  I sat up and started to push him away.  He didn't want to go away so his hind legs stayed put while I pushed his front paws up.

That's when I saw his shaft hanging between his legs.  I had heard about dog's cocks being bigger than mens', but Harley's was huge.  I caught myself wondering how it would feel.

I felt bad, but convinced myself it was just an experiment to see what it would be like.  I let Harley's front paws go and motioned for him to jump up on the bed.  He obliged and was soon standing next to me. 

I reached under him and felt his engorged cock.  I was hot and smooth.  I bent over and took it in my mouth, curious what it would taste like.  Honestly, it didn't have much of a taste, but his precum did.  It was bitter salty.

By now I was so turned on that I didn't care that I didn't enjoy the taste, I wanted Harley inside of me.

I laid on my back and pulled Harley on top of me.  He started humping, but was hitting nothing but air.  I lifted my hips and supported myself with one hand and used the other to guide Harley into me.

Once in, he had no problem staying in.  Harley began pounding my tender pussy like there was no tomorrow.  I was in exstacy.  Orgasm after orgasm washed over my body.  In fact, I thought that Harley was growing with each push, but I told myself it was just that I was contracting from the orgasms.

To my surprise, Harley was growing until finally he pushed extra hard and I could feel his cum shooting into me.  I could feel it welling up inside and I realized Harley's cock, or knot as I later found out, was sealing the entrance and not allowing any to leak out. 

I started to get scared because Harley was finished, but he couldn't get off of me.  He was stuck inside me.  He turned away from me and tried to pull out, but to no avail.  What was I going to do?  I contemplated calling 911, but just as it seemed I might have to, Harley popped out releasing me and most of his cum.

Harley climbed out of my window, but that wasn't the last I've seen of him.
