One Redditor unknowingly had sex with his wife's twin sister after a night of heavy drinking in Las Vegas.
The man goes by notthesis on the social network and said he and his wife go to Las Vegas every few years.
They brought his wife's twin sister, who he describes as a "party girl" with fake breasts, along with them to Sin City two years ago because she had just gone through a messy divorce.
The three shared a room with two double beds.
On their last night, they all got very drunk. Notthesis and his wife went up to the room while his wife's sister flirted with someone at the bar in their hotel.
We were pretty hammered as I had no idea where our room was. Luckily my wife found our room. Next thing you know, I'm face down on the bed out cold.
He soon woke up to find a women, who he assumed was his wife, next to him in a completely dark room.
She seemed "in the mood," so after some touching, they had sex.
But as they cuddled afterward, notthesis realized the breasts he was caressing didn't feel like his wife's.
I notice they were quite firm and almost balloon like. In my drunken state, I immediately froze. I realized I just f*cked my [wife's] sister.
The lights came on just seconds later.
Notthesis' wife found her husband and sister in bed with no clothes on.
She demanded an explanation, to which he responded,
Uh, umm, I didn't... uh umm…
Notthesis tried to talk to his wife, but she refused to listen to him or her sister.
We head back home and she still doesn't say a word to me until we get to our house. She finally talks to me the next day and tells me she needs time to think about things and she packed her stuff and left for her [parents'] house.
The couple is currently finalizing their divorce.
Notthesis hasn't spoken to his wife's sister since the mistake, but he says she forgave him.
