Since my wife cannot have intercourse anymore and meeting up with my "special friend" is Rare, at best, she obliges my needs by Pegging me. My prostate shrunk and I stopped peeing several time through the night. At first it was For My Own Good which was working for me. When I asked for it more often, she told me that I should just do it to myself. Just jerking off doesn't cut it, but pegging works out to be benifical for both of us. Has your wife watched you fuck yourself or will she help you out?
My present wife turned me on to the pleasures of my anus being penetrated. She would do so while giving me oral. Frist with her finger, then a thin vibrating dildo. Over time I purchased longer and thicker dildo's and would work my ass with them while she sucked on my cock and had fantastic orgasms that we shared in snowball kisses. Then I bought a strap-on with a 9" dildo and she fucked me like a man fucks a woman. God, it was so hot to have her fucking me and stroking me off to spew cum all over my chest. My wife has watched me fuck myself many times as well as just stroking myself while she fondles my balls. She loves watching my cock shooting its load of cum and willingly licks it up from my chest and tummy.
Been there, done that, and it's an incredible experience. I admire you for being able to take 9"; 5" is the most for me so far. We also share my cum after I'ver shot a load.
She lets me ride it and cum on her belly. Licking the cum off of her gets me hard again and I usually repeat and hop back on her dildo.
