Present from Mom

I'm Ken 24 single on my last birthday late last month and in isolation with only divorced mom Katherine 43 for company. Both now unemployed until the isolation ends, getting by with food parcels from charities. Katherine couldn't get me anything for a present and having already caught masturbating several times during our isolation. On the morning of my birthday she got naked and wrapped herself in a blue bedsheet with a card pinned to it say to Ken on his Birthday from mom. I came into the lounge room and saw a wrapped lump on the lounge. Mom had curdled up as small as she could and I hadn't thought it was her until I started to unwrap it. I shocked at finding mom total naked and even more when she told me she was my sex toy for the day. At first I thought she was having me on, but she told me she was serious. I asked so I can fuck you if I want and do what ever I want with you today. Yes as long as it isn't painful I'm yours, my cock went hard and I asked her for a blowjob and she gave me one and after I fucked her for the first time. She also gave some pointers as well. By lunchtime I had fucked her tree times and we spent the whole afternoon in her bed. We had more sex after dinner and when I got up to go to the toilet for a pee I noticed it was after midnight and on returning to her bed decided to try for another fuck before realized it was after midnight. Katherine let fuck her again and when we both awoke in the morning I gave her kiss and a feel up. I already had a hard-on and expected her to refuse. But let me fuck her again and I've been sleeping her every night since. Best Birthday present ever.
