At first my wife was very hesitant for doing sph. After she did it the first time, it was at a nude beach with her boyfriend present, and saw my reaction, she started doing it. At the beginning, we talked a lot to make sure everything was ok, but now she does it frequently.
I honestly enjoy it. At the nude beach another lady asked her why she was cuckolding me. She answered, “I love my husband, but look at his cock. It is only good for his hand.” Everyone looked at me and I my little cock got hard. The other lady responded, “I see what you mean.” After that sph started. The first time I heard her say, “your so much bigger than my husband” with his cock in her, I loved it.
