My Mum caught me

Last week I was fucking our old neighbor Yvonne 59 divorced in her back garden, its has high fences on all sides. I've been fucking her for some months and it's just for mutual satisfaction. I'm Bob 23 and work nights mostly 7pm to 4am, so I'm home most days. My mother Glenda 44 also divorced lives with me in a 3 bed 1 bath house. Glenda works days only and was at work when I went over to Yvonne's place. Unknown to me Glenda had come home earlier than usual as there was a power cut at her workplace and everybody were sent home. Being 2 hours earlier than usual, she came out into our backyard to see if I was home. Hearing my voice next door see looked thru a knot hole in the wooden fence and saw me up to my nuts in Yvonne. She didn't say anything until I back home and wanted to know how long had I been fucking Yvonne and why I was fucking such a mature woman. Caught by surprise I told her a couple of weeks and that Yvonne was willing and I don't get out much due working nights and a fucks a fuck. She shocked me by saying that you could've asked me and I would most likely let you fuck me. You'll let me fuck you, you don't date and I thought you didn't like sex I replied. She said I'm not wanting another relationship like with your father and I masturbate most nights. Well I'm not working till 7 how about a fuck then I asked expecting a telling off. You shower and we can fuck she said. Why not join me in the shower I asked and with that she took my hand and led me to the bathroom. After we fucked twice, then I had to go work and on getting back home just after 4am I got naked got into her bed and started to feel her up. She awoke and we had sex again. I awoke later and she was gone to work I showered and then went over to see Yvonne and got another fuck from her. Life's pretty good at the moment with regular sex from Glenda and Yvonne.
