Long-term relationships get stale after a while. We get it. When your sex life stalls and your romantic life is non-existent it’s only natural to start looking elsewhere for a place to get your kicks. So maybe her sister is a drop-dead hottie. Maybe she’s been flirting it up with you in the past. Maybe the time is right for you to get with that. The only thing is you don’t want to break up your current relationship. So how can youstart hooking up with her sister without everything else falling apart?
Keep it Far From Home
“Go outside with your girlfriend”
If her sister lives in the same city / neighbourhood / zip code as you, you need to meet up with her elsewhere. The chances that you’ll run into someone you both know are too high otherwise. It might be tempting to get together at your favorite places, but keep in mind that if you’re there often people will probably recognize you. So get creative. Arrange meet ups in different cities. If taking it out of town isn’t an option you can always rely on smaller motel chains. These won’t be frequented by people you know which means you screw around in peace.
Make Your Excuses Believable
“Have an answer ready for all her questions”
Telling your girlfriend that you’ve got business trips every other weekend isn’t going to fly, especially if you’ve never travelled for work before. Think of other good excuses. One weekend you might be headed out to meet up with some old friends from college or high school. If you want to get with her sister on a week night, tell her you have to stay late at work. If you want to spend an entire day nailing her sister, tell her that you’re taking a course related to your job. Don’t overuse your excuses. If you do she’ll get suspicious.
Too Much, Too Often Is Bad
What we mean is that if you’re coming up with excuses to meet up with her sister every week night and every weekend, your girlfriend will figure out what’s going on fast. So practice some moderation. Even if her sister is smoking hot and willing to put out all day every day, if you do it all the time you’re going to get caught. Besides, putting it off can build up the temptation, which means the next time you’re both naked together it’s going to be explosive.
You need to plan contingencies. If your girlfriend starts to suspect that you’re nailing her sister, coach her sister on what to say to throw her off the track. Always have a backup plan. If your girlfriend was supposed to be out of town but cancelled last minute and comes home to find the two of you in the same house, have a believable excuse ready beforehand. And you both need to sound sincere. If her sister can lie smoothly but you can’t, the game’s over. If you don’t have a story lined up that makes sense, she’s going to suspect something is up.
