My sister in law

About a year ago my sister in law called my wife and told her about a lady she works with. Martin her friend had a rabbit vib like those in sex and the city. She said she loved it. I bought one for my wife. She loves hers too and told my sister in law. I text her a pic of it. She thought it was to big for her. I said it just looks bigger in the pic. She came for a visit, lives about three hrs away. I bought her one and gave it to her when she got here. Her eyes lit up and she said she couldn't wait to use it. I also gave her some I'd lube. She told me to come to her room at 2:00am. I did and she put on a show for me while I jacked off over her We came about the same time. I shot on her tits and rubbed it in for her. She has let me watch her many times since and gave me a blow job which she swallowed.
