Frustrated at Forty

I came back from out of town and spent a long, heavy, day of yard work.  She was very happy with the work and was hinting towards some bedroom action.  I was tired and my back was hurting in a bad way.  Sadly, she had started with a beer with dinner and graduated to wine shortly thereafter.  I tried to keep interested but it soon progressed to sloppy drunk and was not going to be worth the effort.  She passeed out/went to bed hinting that I should come join her.  I peeked in and she was snoring.  When I went to bed, she looked great.  The morning would be better.
I woke up before her again and started kissing her.  I could tell she was a bit woosy from the night before and she tried using the excuse that she thought the kids were awake.  I assured her that they were not.  Then she tried saying that she didn’t want to be ‘dripping’ all day.  I countered that I would pull out if it made it any easier for her.  I was desperate.
She took her shorts off and I spooned up behind her.  She started rubbing me and was kissing the back of her neck.  She inserted my penis inside her from behind and we were screwing.  There’s a mirror on her side of the bed and her expression was a mix of semi-excitement and looking like she was going to hurl.  It kind of was killing the mood for me as well.  I moved a bit more so that I was on top – but still behind her so I didn’t have to look at the expression in the mirror.  She started getting more into what we were doing.  She said it was okay to cum inside her – she would deal with it.  For a brief moment, I thought there would be a chance for some mutual happiness.  I was wrong.
We have a very busy weekend planned, I asked her if she was up for some more fun.  She didn’t cockblock me like she would normally do.  Maybe there’s hope?
