Event was a fail, but not for the lack of effort.

The other man had his chance with my GF and I was actually pretty OK with seeing it Try to happen. He did her orally and with his fingers and she seemed to like what was going on. The shortfall (Pun is Cumming...) was all his as he was unable to get it up for actual penetration. I was Waiting for him to get it inside of her, but that just never happened. After an Hour of him trying, they settled down on the bed together and I finally called it. I simply said, this just isn't going to work, is it? He told me that I would have to finish her off.

That's all of the details I am willing to write about at this time and I will have LilacLove read and suggest edits as she sees fit. So there we have it. It was a One Time thing and he didn't make it happen for himself.
