Watching Porn for Teasing Purposes

Does anyone else have their KH make them watch porn just to play with them? Tonight was a perfect case. My wife went out with friends, and when she returned, she instructed me to keep watching until she had showered and changed into her pajamas. Afterward, she checked if I were semi-hard. Since I wasn’t, she told me to continue until I showed some sign of life. It took about another 20 minutes for a semi to appear; when she saw it, she commented that it was nice and wished me good night.
