My wife Karen and I had tickets to attend a concert, and one of the planned attendees backed out on us at the last moment. Since there was such little notice, and since I didn't know if the concert was sold out, it seemed that there would be no chance for us to sell the tickets, so we decided to invite along my wife's niece Kathi.
Kathi is a tall, voluptuous girl. Just on the edge of being "fat," she has very nice boobs. She likes to dress in lacy, "girly" sorts of clothes, and sometimes she nearly seems to be falling out of them. This particular evening, she was wearing a pair of jeans and a vest-like blouse over a lacy black camisole. The top of her boobs looked like they were trying to escape, and I noticed that a few times before we left for the show, she had to turn away and sort of "adjust" herself to get them to behave.
Kathi, Karen and I had a good time watching the music, but Kathi had quite a bit to drink there. We had to help her to our car, and she was passed out by the time we got back to our house. Karen and I helped Kathi into the house, but it was obvious that she wouldn't be driving home. We got her some spare blankets and pillows so she could sleep on the couch in the living room and made her as comfortable as possible. She was asleep in just a few minutes, snoring quietly in passed out slumber.
I had to go to work the next morning, so Karen and I went off to bed as soon as we knew that Kathi was okay.
The next morning, I walked out into the living room. During the night, Kathi had thrown off most of her covers. She was lying on her side facing into the room, and her boobs were revealed to well below the nipples. My dick got hard in my pajamas, and I was going to go jack off in the shower.
It was a little chilly in the living room, so I picked up one of the blankets from the floor and put it over Kathi. As I did, she moaned a little in her sleep and reached out at nothing. I said something like, "It's okay," and she responded incoherently. I spoke to her again, and again she slurred out some unintelligible response. I realized that she must have had way more to drink last night than I thought, and she must still be drunk.
