Last night I was at a friends house for a party, and I couldn't help myself from cumming.  We were all drunk and I had to go to the washroom to take a piss.  The washroom had two doors, so I closed one when I went in and as I went to close the other one I decided to take a peek to see what room it was connected to.  It was to their guest room and on the bed was one of the guests passed out on the bed.  It was a swim party so she was wearing her bikini and had a towel wrapped around her waist.  I decided to look closer and noticed her bottom hanging over a chair so I knew she had nothing on under the towel.   I slowly pulled the towel and when it came free she her pussy was totally exposed.  She moved a little so I stopped moving and she put her hand between her legs and let out a very soft moan.  I was rock hard immediately! Her hand jest stayed they so I pulled out my cock and stated jerking it over her and then slowly moved it closer to her pussy, as I did that her hand moved and she grabbed my cock, pluming it closer to her now very wet pussy. I started humping her hand and watched as she grabbed my cock harder and but her pointy finger on her clot so as I pumped her finger ruled her clit.  She started moaning louder and I couldn't help it anymore I kept plucking closer to her clot and came a bucketful. She also let out of soft screen of orgasm, rubbed my cum over her pussy and opener her eyes to see who she came to.  When she saw it was me she sat up licked my cock clean and also her fingers.  What a great party!
