Ideally,it's the woman who makes if not the first move her desires obvious.
As long as she doesn't do this no Tips will suffice and you will rock the marriage.
I know that the forbidden fruit is tempting, but I would pass If you have to try, I'd say be incredibly careful! If she wants you she will make it very clear! If you misread the situation and make an unwanted move; she will have no qualms telling her sister about you getting handsy.
I would look elsewhere.
I'd try to hit it in all holes rather than concentrate on just one.
If she been hinting to you but is scared all I have to say is alcohol
My wifes sister used to get me hard . She was only 13 . My wife was still my girlfriend . We used to visit my wifes parents on a Saturday . They would be out in the day . We went for a drink with them at night . The first time it happened . Her sister came down from her bedroom . I was sitting with my back against the arm of the couch . My wife liked to lean against my chest , watching the tv over my shoulder . Her sister climbed on the arm at the other end of the couch . She was wearing a dress . She sat with her legs apart . Making her dress ride up them . Giving me a good view of the nearly transparent panties that she was wearing . Obviously not her own panties . After flashing me like this . She kneeled on the couch . Lifting her dreess to show me her butt . When she saw my wife start to move . She sat down . My wife never saw anything . She started doing this , every time we sat on th couch like this . Not wearing any panties . At first it was just exposing her pussy . Then she would open her pussy lips . This changed to fingering her pussy , and showing me pussy juice on her fingers . Then licking them . She even kneeled with her back to me . Sticking her pussy near to my face . I always wanted to reach out to touch her . Luckily my wife never suspected anyhting . It was hard for me to cover my erection . Her sister looked at with a look that showed she was enjoying taunting me . This stopped when we got married . My wife visited on her own . As i was working on a Saturday .
