I found it hard to sleep that night knowing that the next morning I would be with my son and keeping this news from him. I really wanted to tell him the good news that I was pregnant with his child but at the same time I thought once he knew there would be no reason for him to keep up our sexual relationship.
I had already deceived him once by not telling him that I never actually used the turkey baster method to try and get pregnant and in fact I had just eaten all his cum he had left in my coffee cups.
I was going to lie to him again and I felt bad about it, but it seemed at the time the less painful of my two choices. I just wasn't ready to give him up as my lover.
I was still in bed when Tom arrived the next morning. I had over slept due to having a bad night tossing and turning.
"Morning mum," Tom called out as he walked in my house, using his own key and locking it again behind him.
The sound of his voice woke me from my restless slumber and I sat up in bed, rubbing the sleep from my eyes.
"Oh you're not even up yet mum?" he said, mildly surprised as he walked into my bedroom.
"Oh is it that time already son?" I asked as I glanced over at the clock.
"Yes, come on sleepyhead. Rise and shine mum, you have a date with your son. Remember?" Tom said cheekily as he pulled back the bed covers, exposing my naked body.
I smiled at him and got out of bed, groggily walking towards my bathroom. I was still a bit dazed and didn't even bother to shut the door as I sat on the toilet to pee. I glanced up at the door while I was urinating and noticed that my son was standing in the doorway watching me. He was always watching me these days and he didn't even seem to have any intention of giving me any privacy.
I always stand up to wipe myself after I pee and I know I could have discreetly reached down between my legs and wiped myself but I thought if he likes to watch me, then let him watch. So I stood up and wiped my drips of pee from my pussy, discarded the toilet paper into the bowl and flushed.
Then I washed my hands and brushed my teeth, the things that I normally do before my son arrives for his daily fuck. I couldn't help but think this all could be coming to an end soon, and the thought both saddened and scared me.
I was hoping none of my thoughts were obvious to Tom as I walked over to him and kissed my son passionately. I loved to kiss him, the way he would hold me in his strong arms, firm yet lovingly and kiss me as if I was his first and only love, just made my heart melt. I knew that Jen was his first and that he still loved her as well as me, but the way he kissed me made me feel like his one and only lover.
"Good Morning son," I said when we pulled back from our embrace. I smiled at him lovingly, hoping my smile would cover my deceit.
I then began to undress him like I had every other day since we had been having sex. Tom really seemed to enjoy me taking his clothes off for him rather than do it himself, so it had become part of our regular sexual routine. The way he got excited by me 'mothering' him got me to wondering if he might enjoy a little bit of parental discipline and knowing that our time was limited now that I was pregnant made me think that perhaps I should try a few more things with my son before all of this wonderful sex came to an end.
"You're a naughty boy peeking at your mummy while I was in the bathroom, aren't you son?" I asked in a wickedly seductive tone as I discarded the last of his clothing onto the floor.
"Yes mummy," replied Tom, blushing a little.
"Naughty boys need the occasional spanking to keep them in line," I responded as I reached around behind him and gave his bare butt a playful smack.
"Oh yes mummy. You are right as always mummy," answered Tom and then he surprised me by bending over and resting his hands on my bed with his bare ass sticking up in the air. He even wriggled it a little, almost begging for it to be smacked.
This was even better than the response I was expecting from him. I grinned in delight as I rubbed my hands on his cute bare ass. He has such a nice ass, it looked very spank-able indeed. My dominant streak suddenly getting the urge to smack his cheeks hard until they glowed a bright pink. But my sense came back just in time to remind me that I wanted to turn him on, not freak him out.
So I smacked his right butt cheek with my right hand. Firmly but not really hard. It made a great 'smack!' sound and made Tom jump a little. But it also made him gasp and it was most definitely a gasp of pleasure and not shock. So I slapped his left cheek too, resulting in another small gasp following by a slight moan. My boy seemed to be enjoying this.
"Naughty boy!" I scolded as I smacked his right and left cheeks again a little harder this time. It made my hand sting a little so I know it must have done the same to my son's ass cheeks.
I could feel the beginning of a warm glow on his cheeks and I had to fight my urge to dominate him more as this was really exciting me. My pussy was already very wet and wanting my son's hard cock immersed in me. It seemed by the pleasurable moans coming from my son's mouth that perhaps he would also enjoy some Dom/sub play but now was not the time but it was food for thought. Ideas to be filed away for later, for now a few firm smacks would suffice.
I stopped smacking him and turned him around to check to see if the spanking had aroused him.
Not only was my son hard as a rock but his beautiful cock was seeping so much precum that I really didn't need to ask if he liked that or not. Tom also looked a little flushed; he was definitely very excited from being spanked by his mother. I have him a wicked grin.
"Oh poor baby. Mummy didn't mean to smack you so hard. Turn around again son, let mummy kiss it better for you," I said lustfully.
Tom turned back to his position of leaning on the bed. I bent down and kissed both cheeks where it looked all pink from my hand slapping him. Then I licked where it looked tender and continued to lick and kiss his cheeks, my lips and tongue going from one cheek to the other. Then I grabbed hold of those pink cheeks and pried them open with both my hands, exposing my son's puckered hole and I licked from the top of his crack down over his hole to his ball sack and back up again.
This resulted in a low groan of pleasure, which inspired me to continue. I licked up and down his crack from the top of his crack to the back of his balls a few times, causing my son to begin to pant. I then licked all around his hole giving my boy his first rim job. Tom loved it, he was moaning in pleasure and panting with desire and then he began to push back against me slightly. I took that as a 'yes please' and pushed the tip of my tongue right inside his tight little hole and darted it in and out.
I enjoyed tongue-fucking my son, mostly as I could tell by his reactions and sounds of pleasure he was making that he loved this so much.
"Oh God! Oh fuck that's so good mum. Oh yesss!" he moaned, "Oh fuck! Mum, you had better stop or you are gonna make me cum."
Not wanting to waste my sons cum by letting him cum onto my bed, I stopped tongue-fucking his hole and quickly moved from behind him to kneel in front of him. I grabbed his hard twitching cock and engulfed it into my warm mouth and sucked up all his delicious precum. There was so much of it, no mistaking that Tom loved the anal stimulation I had just given him. I knew he would want to cum inside me as he didn't know I was already pregnant but I also knew he was so close to cumming it wouldn't take much to push him over the edge.
I sucked on his cock deep and hard, making cooing sounds of delight as I enjoyed his flavor.
"Mum! Oh fuck! You have to stop mum, I can't hold back much longer," Tom exclaimed.
I looked up at him and I could see the strain on his face, he was using all his will power to prevent from cumming. But I wanted him to cum in my mouth. I loved the taste of his cum and I knew I didn't have to try to get pregnant anymore. I just wanted to fuck my son for the sheer taboo pleasure of it.
My devious mind clicked on my 'wicked' button and I stopped sucking for a moment, looking up at my son, who had sweat on his brow from concentrating so hard not to cum.
"Aww but I don't want to stop son," I said pleadingly, "Mummy is so hungry baby. Please Tommy, feed your mummy your cum."
I had looked him in the eyes when I begged him for his cum while still holding onto his cock. I knew my pleading would excite him too much, so I quickly went back to my oral assault and it only took a few more deep hard sucks when I was rewarded with a mouthful of my son's warm essence as he spurted a load of cum onto my waiting tongue.
"Ohhhh fuck!" Tom groaned as he climaxed.
"Mmmm so nice," I said in pleasure after swallowing my reward for my oral efforts.
Tom sat down on my bed, and then lay down. He looked like he needed to catch his breath. He was still panting a little when I got on top of him and leant down and kissed him.
"That was so intense mum. Damn that was good. But aren't I supposed to be cumming somewhere else?" Tom said with a touch of cheekiness in his voice. "Or have you got your period again mum?"
"No I haven't yet son. I'm sorry baby; I just needed to taste you again. I couldn't help myself," I replied a little guiltily.
Tom smiled at me. I knew he wouldn't really be mad at me. It's kind of hard to be upset with someone who has just made you cum so good.
"That's ok mum. I don't have to be at work until ten this morning mum. I have a meeting at ten o'clock, maybe we could go again," Tom suggested with a grin on his face, "I like it better when you get to cum too mum."
I was way past worrying about being late for work and I wasn't sure how long I was going to be able to keep my secret from my son. Also I still had something I had wanted to do with him, so perhaps today was the day.
"I would love to make love to you again son. Do you want me to suck on you now to get you hard again Tom?" I asked. Then before he could answer, I lent down and whispered in his ear, "Or would you like to lick your mummy today?" I said quietly and seductively in his right ear.
Tom gasped and then grinned at me.
"Oh God yes mum. I've wanted to taste you for so long now. I just didn't know if I should," Tom replied keenly, "You already give me so much mum. I didn't like to ask for more."
I smiled at my son and then leant down and kissed him passionately. He didn't mind anymore if my tongue tasted of his own cum and he didn't seem to care that the tongue he had in his mouth had recently been tongue-fucking his ass. Maybe the idea of it even turned him on because he kissed me like he was wild with passion. Or perhaps he was just excited at the thought of getting to go down on his mother, to lick the pussy that gave birth to him many years ago.
