Mother in law at 5am

After our wedding we had to live with her family for 8wks till our house was ready. Her mom was only 42, had my mrs young and we flirted for the 3yrs I was with her. 4wks in we had a row and I grabbed a quilt and slept on the floor downstairs. She told her mom n dad n sister I was down there as they only had a downstairs loo. He came down about 4am to go to work and I feigned sleep. About 5am I heard the stairs creak, it was light and I saw Pat thro the glass door, checking her hair in the mirror as always. I got a semi just with her blurred shape so I lay on my back and flicked the quilt off. I squinted and she had a small bra on and a panty girdle, she slept in one. I heard the toilet flush, I was rock solid, 7 long but wrist thick., she came thro the swing doors quietly and stopped dead. I had a roll about opened my eyes and just said “Good morning”, she replied the same, but remained stood there. I looked at him then her and said, “Oh sorry about him”, No its ok she whispered nervously. I moved the quilt off me and said, “This might be our only chance, If you want?”. She took steps towards me, not the stairs door, unclipped her bra, really small but firm tits and rolled her girdle down, hairy but trimmed. I lay there as she straddled me. hand on my chest, she eased my head in then slowly rode up and down, Ok?, I asked, She’s a lucky girl, she replied. She rode so well, with her hips and gripping him tight. I had a play with her nipples and grabbed her small tight ass cheeks. We have to finish, Incase the girls wake, so every downstroke of hers i pushed him up hard to meet her. She lay flat on me and I took over, quickly she buried her face in my neck and said, “Omg, Omg I’m going to cum”, I shot everything inside her as she grabbed and shook, a lot of juice squeezing past my cock. She jumped up, dressed and said, put the quilt in the washer when you get up. The next day as we passed in the kitchen she whispered, “Thats the first time I have done that since I was 19, Thank you!”
