I promised my son that he could get me to do anything he wanted for a whole day if he got all A’s on his mid term and which he did it, and so to make good on my promise I did whatever he liked today. The first thing my son did was to strip me completely naked. My son often loves to show up while I’m taking a shower, or yank my towel away from me when I’m coming out of the shower; he doesn’t get to see my naked body as much as he likes, but today is different. Today I’m my son’s free use toy and I did whatever he liked. And as soon as I was naked my son started to spank my ass really hard. His dad used to spank him when he was younger and he said “Today, I’m your daddy” and he spanked me so hard I was literally whimpering and begging for mercy. But it was no use and he spanked me so hard I couldn’t even sit down anymore and my son made me call him “Daddy” as he spanked me. He knew I enjoyed spankings because he often heard uncle Jim spanking me before sex after my divorce. 

After my ass he moved on to my tits. He loved to play with my nipples and even though he is already 18 years old, he still likes to play with my tits and I didn’t really like him doing that because I felt embarrassed, but today is different. Today is his day and so I let him have a go freely fondling my tits, biting my nipples, and suckling them as much as he liked. 

And after my tits my son started going at my pussy. He touched the mound of my pussy first, and then he moved onto my vaginal openings and he used his fingers to spread open my pussy and he stretched on my pussy lips like they were toys. When he took out his hard cock I hesitated and I told my son that I’m not on the pills and besides, it’s not right for a son to fuck his own mother, but my son told me that I better get on the pills because he was going to start cumming inside me and he even suggested that I should have my tubes tied in the future just so he can cum inside me whenever he wanted. I have always known my son to be a very dominant young man but I never imagined that he was still dominant and I asked him perhaps you can put on a condom but he told me that he would only put on a condom if he’s fucking a whore. “You are not a whore, are you, mom?” Of course I’m not and so I ended up fucking my son without a condom and he came inside me a total of 7 times in the last 12 hours.

My pussy feels so sore right now but my son is not done yet. He said there are 12 more hours left to go and he is now asking his friends to come over so they could all take turns gangbanging me. The last time they fucked me I squirted all over myself and I get horny just thinking about all those 18 to 19 year old boys and their big white cocks.
