If I take the case of my wife (an assertive bisexual) was initiated by one of her friends while she was at home and both of them were relaxing after some torrid lovemaking.At one point, her friend got up and opened the bedroom door and her medium-sized dog jumped on the bed and came straight to put his muzzle between my wife's legs. At the time, she was a little scared, but her friend immediately reassured her and demonstrated everything she was doing with her dog. And that's how she convinced my wife to give it a try. And since then, my wife has been a follower. I like to see her having fun at home and I also like it when she comes back after spending the day or a weekend at this friend's house and she gives me some little videos of their adventures with their boy.
