so last night I saw a side of my wife I have never seen. she was playing with me then flipped me over smacked my ass told me to get on all fours and got the lube and her vibrator. now I have no problem with this since we use it for prostate stimulation while she is playing with me. but I now have a new found respect to how slowly you should enter a womans ass. she went in too fast and now my ass feels bruised. how long will this last?
