Masturbation With My Wife

I may be 58, but it seems my sex drive is still running on high. Unfortunately my wife has arthritis and is going through menopause. Our sex life has dwindled, but she understands my horniness and genuinely tries to keep me happy. Masturbation has now become something that I not only privately enjoy but has become a way for her to help me get off. Sometimes she will stroke my cock and play with me, sometimes she will suck my balls while I pump and cum. Yesterday she woke up and could tell I was horny. I was on my stomach and she started giving me a back rub, slowly working down to my butt. After a while she was actually sliding her hand up and down my crack, gently sliding her hand over my ass hole. I could feel my cock getting harder and wanted to arch my back to give her more access, but she was sitting on my legs while rubbing and teasing. This continued until she moved off my legs and I slightly lifted my ass. Wow...now she could really tease my ass, stroke my cock and balls. I was really starting to feel good and wondered if my cock was leaking cum. She wet her finger a little bit and poked and prodded my ass hole, sliding it inside a little bit. She put her finger in a tiny bit and starting making fucking movements with it...I was now moaning my approval, wanting more. AS she turned me on more I lifted my ass higher until I was on my knees with my head down, asking her to stroke my cock while she teased my ass hole. The sensations were running all through me, I actually was starting to shake a little. She was on her knees behind me...I tried to reach back and play with her pussy but couldn't reach it; damn! Wow...the sensations! She was playing with my ass, stroking my balls and feeling that little area between my balls and ass~ while slowly stroking my cock with her other hand. I tried to hold off from cumming but could not...I shot all over the bed while she pumped the cum out of me...wow! What an orgasm~ next time it is her turn to lie back and let me please her!
