Wife's younger sister
Long story short, 10 years ago when she was 16 my wife's younger sister Jenny gave me a b******* and I came in her mouth. Then I went ate her p**** until she came.
It was her first time for both and she really like it.
Since that day, we have have long 69 sessions at least 3 times a week on the nights my wife works at night so we have time.
I think my wife knows, as she told Jenny it great that she stay over night with me, so I don't go to bar with all those whores.
At least i know you to enjoy your time together.
