Vacation Jerkoff

Recently took my wife (37) and her sister (39) on a work vacation with me. We stayed at a nice hotel with a heated pool. The last night there they had a bit too much to drink and wanted to go swimming, but we had hell finding bikinis during the winter. Luckily, we finally found some, but they weren't the best fitting. They are nearly identical size women, 5'3" 125-130 lbs, but my wife's was a bit too big and my sister in law's was too small. There were more than a few slips that night. My wife's bottoms kept slipping down her ass and her sisters nips popped out about a dozen times. After we got back to the room they kept drinking and acting a fool. The more of them I saw bouncing around in their bikinis like girls half their age the harder it was to contain myself. I knew that after they passed out I was going to have to go into the bathroom and jerk it furiously. They finally settled down and passed out around midnight. After making sure they were out cold, I grabbed the hotel lotion and started to head to the bathroom. I stopped and thought there was no need to go in bathroom, an earthquake wouldn't wake them. They were both laid out on one of the king beds so I gently repositioned both of them for a good view, exposed my wife's tits, and began flogging my cock. When I nutted I tried to contain it all but the first spirt ended up launching onto my sister in laws inner thigh. I watched as the small shot of cum I missed slowly ran down her inner thigh an inch from her pussy and then went and showered. By far the best jerk of my life!
