Girlfriend’s Hot Sister

My girlfriend has a sister who looks very similar to her and they’re only a year or two apart. I would love to have sneaky sex with her and my girlfriend never know. She is just so hot and something other than my girl would be a fun change. I don’t know how I would make this happen without getting caught and I don’t think she would ever approach me about it. Any thoughts?

Alcohol could help, and if not, how about a ski mask? She can't tell on you if she doesn't remember or if she didn't even know it was you!

I’m in relationships with two of my wife’s sisters. Neither one sleeps with their husbands anymore and I stepped in to help. All three of them feel, taste, moan and fuck different. Makes me wonder what mom is like.

It's risky but one way to broach the subject is first trick your girlfriend into cheating on you with a random guy. Then she'll owe you one. Then when you, your girlfriend and her sister are together alone bring up the subject of how sisters are alike and how they are different and attempt to find out as many ways as they are alike and different and after a few dozen such questions steer the conversation to sexual attributes and see if you can arrange for some sort of sex contest to see which one is best at one thing or other. Sisters often compete with each other. They might see it as a challenge to see who can fuck better or suck better or kiss better.

My experience comes from being caught kissing my girlfriend by her sister who told her she was doing it all wrong and offered to show her how to kiss by demonstrating on me and to my shock my girlfriend agreed to let her. For the next several hours each went back and forth kissing me and both asked me to critique their techniques and for me to monitor my girlfriend's improvement in kissing skills and this eventually evolved into comparing blow job techniques and finally fucking techniques. Those two were highly competitive.
