My parents divorced when I was 16. My father married another woman. Soon the stepmother moved in with my dad, and she brought her daughter from the first marriage. So I got a stepmother and a stepsister. Stepsister’s name was Lina.

Lina was one year older than me, slim, blond, and very sexy. One time, Lina came into my room for an “Honest talk. ” Our “honest talk” ended up with Lina touching my cock and doing me a great blow job. After that, we became best friends. She had a boyfriend with whom she had an “on and off” relationship. But she did not mind having intimacy with me sometimes when her boyfriend was not around.

One day, when our parents were out of town, I invited home my new girlfriend Mila, from my class. Mila was a sweet petite girl, a brunette with brown eyes. She was adorable as a doll, but still a little shy with me because it was just our first private date at my house. I was a little nervous with her too, telling the truth.

We sat on a sofa in my room. First, we started doing our homework together. Then I started touching her hands gently and kissed Mila on the neck. She giggled uncomfortably and moved away from me a little. That was all we did the first time.

Later, after Mila left, I told my stepsister Lina about my disastrous first date with Mila. Lina laughed and told me confidently, “Just call me in, when your girlfriend Mila comes next time and let me handle the rest. ”

“But won’t you make her shy even more?” I asked with surprise.

“Don’t worry, brother, ” replied Lina, “I know how to handle that sort of thing. Just trust me. ” Then Lina smiled and left the room. I sat quietly for some time, puzzled about what Lina was about to do.

After a week, I invited Mila to my house again. We sat in my room uncomfortably, and Mila was shy about what we were about to do. “Maybe she was still a virgin?” I thought with bewilderment. I was unsure about the next step myself.

Suddenly the door into my room opened and my stepsister Lina appeared from the doorway and entered my room nonchalantly. Lina was dressed in her usual skimpy outfit, i. e. tight top that stretched around her tall breasts, skimpy thong panties, and barefoot, nothing else on her. Lina came inside and sat on my bed in front of us. Mila was perplexed at first, seeing another sexy girl walking almost undressed around my house.

I introduced them: “Mila, this is my stepsister Lina... Lina, this is Mila, my girlfriend. ”

“Hi, nice to meet you, ” they both said to each other and both giggled.

After some unimportant girls conversation, they seem to begin liking each other. Suddenly Lina spoke about the main topic.

“Have you done a BJ to my little brother already?” asked Lina, smiling innocently, as if saying something usual.

“No, ” Mila shook her head in surprise. She was too shy to discuss that topic so openly.

“Nothing to be ashamed of, this is what any good girlfriend should do to her boy, first thing in the morning. ” Lina laughed sincerely.

But Mila was red from the embarrassment. Perhaps, Mila never did BJ to anyone before, I thought.

“Come on, Mila, ” said Lina in a compassionate tone, “Nothing to be ashamed of. Let me show you how it is done. ” Then Lina with a smile unzipped my pants and pulled out my cock, which was already hard and throbbed with excitement.

Lina bent down on my lap, holding my cock in her hand, and kissed the end of my cock gently. “Mmm, ” said Lina, and took my cock into her mouth completely.

Mila looked at that with scared eyes and babbled in a thing voice, “But Tom is my boyfriend, what are you doing?”

“Relax, ” said Lina, smiling, “I am not taking Tom from you. Tom is my little brother. I am just showing you what you should do next time when you are along with him. Just observe and learn this. ”

Then Lina took my penis into her mouth again and started bobbing her head up and down. Lina opened her mouth and started leaking, moving her long tongue around my cock. My cock got very hard and I felt my heavy breathing.

Mila looked at that with wide transfixed eyes. Mila licked her lips and breathed rapidly, as she got excited from that too.

Lina glanced up at Mila and asked softly, “Do you want to try that now?”

Mila suddenly came close and practically pushed Lina aside. Then Mila bent down between my legs and took my hard cock deep into her mouth. My penis was very hard and the end of it became wet with her saliva and my sperm. After a few deep moves, Mila suddenly made a disgusted look and nearly gagged. Her face became pale.

“Take it easy, girl, ” said Lina with compassion. “Relax, just observe it again. Lick with your tongue around it. Don’t try to get it too deep into your throat. It takes practice too. ”

Then Lina took my cock into her big mouth again and continued bobbing until I could not hold it any longer and exploded with a wild orgasm. Lina opened her mouth wide and showed her mouth full of sperm to Mila. White sperm leaked over Lina’s lips and tongue. Mila’s face went pale and she appeared angry, probably because Lina got most of my sperm before her.

Then Mila pushed her aside and started licking my cock too, getting the rest of the sperm in her mouth. Then they continued licking my cock, taking turns and pushing one another aside. I could not believe my eyes, two sexiest girls pushed each other aside, practically fighting for my cock!

In the process, Lina pulled down her panties and showed her cute round butt and pussy.

After some time, both girls got tired and my cock fell and relaxed. We all got quite exhausted from that game.

We looked at each other happily. I kissed both girls on the lips and necks and cheeks and the girls also kissed one another, although they were not lesbians.

After some time my step – sister stood up, and said to Mila, “See, it is so easy if you want to do that. Do it good to my brother next time. ” and Lina smiled.

“But if you need help again, then don’t be shy, call me, we will play with my brother again. I am all for it. ” then Lina smiled, pulled up her panties, and left the room, moving her hips with every step, like dancing.

We looked at each other with Mila, slightly bewildered. Mila left but she promised to come again to me the next time after the school day. Soon after Mila dressed and left.

When Mila left, I told Lina, “You are the best stepsister I could imagine!”

She just giggled.

After that, Mila came to my house many times and she never hesitated to take my cock into her mouth. Mila was not shy at all after that. She became a real wild sex goddess.

Soon I learned to leak Mila’s cute little pussy every time after she did a BJ. That excited her beyond wild imagination. Mila was ready to jump on me and eat me. Sometimes, Lina joined our company and participated in doing BJ to me, taking turns with Mila; both girls laughed insanely. They even competed with each other about who managed to get more sperm into one’s mouth, after I cum. I had a picture with Mila and Lina together, both of them stood with open mouths, showing how much of my sperm they got. White sperm leaked over their open mouths, lips, and even chins. It was the funniest time of my teenage sex life.
