Nothing happened the rest of the night as Lisa was completely spent from her being fucked.
The next morning, Richard and I got up and hit the shower together. It was nice having our cocks touching each other and washing up. As we were finishing up, Lisa stuck her head in and said hi with a big smile.
Richard and I finished up and went into the kitchen where Lisa already had coffee waiting for us.
I asked Lisa how she was and if she remembered last night.
Lisa said she did not really remember anything except that she had a great time and hoped the rest of the weekend would be even better.
Richard asked Lisa, "Do you remember what you said when I asked you what you really wanted?"
Lisa looked at both of us and said to us that she did not remember.
We finished breakfast and headed back to the bedroom.
This time, Richard and I gave Lisa a show and got into 69 and sucked each other until Lisa got between us and split us apart.
She told us that she wanted to get fucked in both holes at the same time.
Richard got on his back and Lisa mounted him, sliding his cock in her cunt. She leaned forward giving me access to her ass hole. I slowly inserted my cock into her hole and I could feel Richard's cock through the thin skin. I finally got fully seated in Lisa's ass and Richard and I got into a rhythm.
It didn't take long for me to shoot my load in her ass. As I pulled out, my cum oozed out and onto Richard's cock.
Richard kept fucking Lisa and in no time shot his cum into her. She moaned as each cum stream hit her insides with a powerful force.
Lisa lifted off of Richard and fell to the side and passed out from exhaustion.
Richard. and I went into the kitchen to discuss Lisa.
Richard and I looked at each other in disbelief. We figured that there had to be a reason for all this.
Then, it hit me. I told Richard I bet I know what the problem is. I told him it had to be the wine he brought. She must somehow be allergic to the ingredients that made her act and talk like that.
I told him we would test my theory later on.
Lisa came out of the bedroom and told us she was showering. After her shower she looked radiant with water still on her. I told her that Richard wanted to fuck her now, before we went on the trail. Lisa's eyes lit up and went immediately to the bedroom, with Richard following.
I let them alone so they could fuck in private. When they were done, we grabbed our towels and were ready to go out, when I suggested we have a toast to a great weekend.
I poured some of Richard's wine and we all had a drink and then left.
On the trail, Lisa started acting and talking funny. She kept talking about fucking as many guys as possible and wanting everyone to know that she was a cock slut.
Richard and I looked at each other and I told him I was right, that it was the wine.
Without telling Lisa anything, we continued on our walk and hoped the wine would wear off soon.
