There are occasions where the mind may be willing but the body just won't listen and does whatever the hell it wants. This is especially true during sex where the guy wants more than what his cock can handle. We had been fucking non stop for 5 days straight with my ass, pussy and mouth were used multiple times each day. When it came time for us to do this scene all three of my fuck holes were ready to throw in the towel. But I had one last job to do and this time it would just be my mouth that gets used. At this point I would like to point out that his cock was also feeling the same way as my holes were but the thought of getting a blowjob with a happy ending on my face seemed like the perfect motivation for him to perform once again. I sucked and slobbered over his cock in various positions but after he came on my face he got greedy and wanted me to keep going for another load. I naturally love a challenge so I doubled down on his request and was trying to drain his balls again, but unfortunately all the work his cock had been doing over the past few days finally caught up with him and he was not able to deliver. Ohh well ... we can always try again tomorrow ;)
