This story happened several years ago and was the beginning of an even better relationship with my stepmother - and her daughter, my stepsister.
When I was 12, my mother died. It took some time for both my father and I to get over it, but a few years later, when I was 16, my father remarried. Incidentally, he married his private secretary for the past 10 years, Jytte.
Jytte was and is a beautiful darkhaired woman of about 40 when they got married, and she had an 18-year-old daughter named Hanne. Jytte was a very sweet stepmother, but Hanne, on the other hand, was quite annoying. She was always busy with new guys, but as Jytte said, she just needed to let off some energy before she calmed down.
Ever since Jytte and Hanne moved in with us, I've been looking at Jytte, and like all other boys at that age, I fantasize about women.
One summer, a little more than 3 years after Jytte and my father had married, she and I had developed a really, really good relationship with each other. We always had a good time together.
But then, this summer day, I had been to soccer and came home at 3 p.m. Apparently no one was at home, at least dad wasn't, because he was on a business trip. Then I heard that there was someone in the bathroom, it was Jytte who was in the shower. I crept to the bathroom door and peered in through the keyhole. She had just gotten out of the bath and was starting to dry herself.
She has nice breasts and a tuft of hair around her pussy which is completely black, just like the hair on her head. Looking at her made me horny and my dick started to harden. I was only wearing shorts after playing soccer, so it was quick to pull them down so I could masturbate to the sight of Jytte, who had now finished drying herself. She put one leg up on the stool and started looking at her pussy in a hand mirror. She found a pair of scissors in the drawer and began to trim the hair on her pussy. When she was done, she opened her pussy opening by holding out her pussy lips. I was now really horny and had a cock that was about to explode. The boys at soccer call me "the Stallion" because my dick is slightly bigger than theirs.
Jytte had now started playing with herself by tickling her clitoris and I could see that she was getting more and more horny. She put a few fingers up her cunt and drove back and forth. I had now become hornier, and therefore a bit careless and clumsy, so I came to touch the door, so it opened.
Jytte let out a startled gasp, and then came over and took a firm hold of me and asked.
"What are you doing?"
I stammered
"Nothing...!"
Then she spotted my stiff cock that had started to sag a little due to the situation, and then asked,
"Is it like that because of me? Have you never seen a naked woman before?"
I answered "no". Then she went and closed and locked the bathroom door, turned to me and said,
"Take off your shorts and lie on the mat in front of the tub!"
I obediently laid down on the mat. She looked at me for a bit and then said,
"That's quite a specimen you have there," as she looked at my cock.
"Could it perhaps be used for something?" She said.
Then she knelt down and gently took my cock.
"You have to promise me you won't say anything about this to your father," she said.
When she grabbed it, it started to grow again and in 0.5 it was as big as before the doors opened. Jytte gasped and said,
"That's the biggest dick I've ever seen, I just have to have it!"
She straddled me and lowered herself over me, took the cock in her hand and guided it into her pussy. She slowly lowered herself onto it as she moaned,
"God, it's so good, to think a young man your age has such a beautiful big cock, we have to use that many times in the future."
The cock was eventually all the way to the bottom and Jytte began to slide up and down on the cock. It was the most beautiful sensation I had ever experienced and after a short moment I moaned,
"I squirt now."
Jytte said,
"Yes, come on my boy, you can surely many more times."
I squirted and squirted right up her pussy. A little later, when my cock had gone limp, Jytte slid down from me and took my cock and said,
"Maybe we can bring you back to life."
Then she kissed it gently, opened her mouth and took it in her mouth and began to suck on the cock. It was almost as good as fucking her. My cock started to come back to life and soon it was as hard as ever.
"I thought so," said Jytte,
"Now we have to get serious, and this time I want to come too!"
Then she stood up with her hands on the stool and her back to me.
"Come, stand up and take me from behind."
I got up and went around behind Jytte. She grabbed the cock with her hand between her legs and guided it into her pussy.
"Now you have to drive the cock in and out, first slowly and calmly, and when I say to increase the pace, you do."
I did as Jytte said, and Jytte began to moan,
"Oh, how wonderful it is, it's a wonderful feeling to be fucked by a real cock, now come a little faster and harder, come now Jens, faster and harder."
The cock went in and out like a piston, and I couldn't hold back any longer. Jytte moaned loudly,
"I'm coming now, I'm coming now, come Jens squirt in me, you lovely boy."
I squirted my cum into her for the second time and she moaned and whimpered, then knelt down on the mat and said,
"It's one of the best fuck I've had in a long time, we'll have to do it again very soon, but remember now, don't say anything to your father when he gets home!"
Then Jytte stood up, turned around and kissed me hot on the mouth.
"My darling little boy, now get out, I have to finish here, I have to go shopping."
I put on my shorts and walked out of the bathroom and into my room, I laid down on the bed and thought about what had happened. I must have fallen asleep, because I woke up to find Hanne standing in my room with a cheeky grin.
"Well, well, you seem to have used your lower limb," she said.
"What do you mean," I asked.
"So, I came home early and heard you and mom in the bathroom!" She said and I blushed deeply and stammered,
"You must not say anything to father."
She laughed and cheekily said,
"It's going to cost you."
"What do you mean?" I asked.
Hanne went forward and grabbed my shorts and pulled them down around my ankles.
"I want to be fucked just like my mother, and you don't have to be afraid, I don't gossip and Jytte has gone to town,"
