I bought my wife a razor strap when we were in our 30s and she definitely put it to good use. She licked my ass cheeks with the strap between 200 and 400 times depending upon her mood. Sometimes she would have to tie my wrists to the headboard because I couldn’t hold still enough for the whipping. After the whipping, she would strap on her favorite, 9 inch dildo, and fuck my ass for another half hour, teaching me a real lesson.
