First time Spanking – Any Advice Appreciated

I have just started to punish my wife and would like advice and guidance. I will regularly upload progress until she learns her lesson. Her first lesson was bent over, butt on show for 10 mins in a closed room, this didnt work so the next time I gave her a spank until her cheeks turned pink, again it didnt work, so I then gave her the same spanking, but took pictures and warned her I would put them on here for all to see if she didnt learn. Obviously she has not learnt, so here they are. Would someone please take a look and let me know if I have spanked her hard enough as she just doesnt seem to learn... please advise me, I will photograph the punishments and upload them for your approval and further guidance, Many Thanks in Advance... oh btw, she has been warned the next pictures will either be outdoor spanking or private pictures of spread legs, close up shots... both will be uploaded... It is now 4am and she still isnt home, what do you think?
