   That is totally not right! Yu should not be having sex with your younger sister and her husband! You have a family, jobs etc you should not be being led astray SEX! i mean surely there is more important things than sex! It's not right, i totally object to the idea. Of coyrse you may hav sex whenever you want.. but not with your younger sister and her husband. It's wrong. S

   My wife and I have been swapping with her sister and husband for five years now. We all enjoy it. I see nothing wrong with it as long as you trust your partner. sorry if this has nt been any help.

   HORRIBLE idea... my sister-in-law (younger) is really cute, funny and sexy, however, she's about the LAST person I would invite into our bed... that's TOO CLOSE for any comfort. If you're going to play, find someone you can play with and never see again if something happens. Someone whe doesn't know you, and you will not run into... if it works for a year, great! If not- no harm...

   Don't do this... not with family, or even freinds that you know outside of swinging. Swapping can be great fun, under the right senario, but this is the #1 DO NOT DO... don't swing with family, co-workers, freinds... make new freinds to swing with - and keep those freindships focused on sex.
