An unexpected outcome

It’s 12:00 o’clock and I head home to eat lunch. When I enter the kitchen the three of them are already eating. When they saw me they were surprised about the changes of my body. “Don’t worry, this is completely normal” I said to them and they agreed. I sit on a chair and I start eating. “David, after lunch I have free time, you can give me a healthy fuck if you want” My sister said to me. “Excellent! When you finish eating go to your room and start masturbating until you cum and wait for me.” I told her. “Yes bro.” She replied. When she finished eating she went to her room and five minutes later I finish my meal and head to my sister bedroom.

I knock in her door and enter when she told me I can enter. She’s lying in her bed with her legs spread open. You notice she’s already wet. I start penetrating her slowly and some blood is pouring from her pussy. When my cock is fully inside her I start kissing her passionately. She’s a bit surprised but she respond the kiss. We keep kissing for two minutes. “I’m going to start thrusting slowly and the pleasure you feel is doubled” I said to her. “You’re right.” she replied.

I started thrusting and she moans very loud. Her pussy is pressing my cock very hard. I start playing with both of her breasts, they’re perky but small, I prefer bigger breasts. “You have E cups breasts.” I said to her. “You’re right.” she replied and her breasts got bigger. I start sucking her left breast. “You enjoy having sex with me, you want to do it often” I said to her. “Yes, this is amazing, please fuck me a lot.” She replied and she came. I start thrusting as fast as I can. “Where do you want me to cum?” I asked her. “In my tits.” She said. I pull out and cum in her tits.

“Please, keep fucking me.” She said to me. I put my cock inside and start thrusting at full speed. She starts kissing me again. The pressure on my cock is a bit lower now. “You love as a brother but also as a man.” I said to her and she agreed. “You can cum inside me bro, I don’t mind being impregnated by you, you’re the man I love after all.” She told me. After hearing those words I couldn’t hold back any longer and I came inside her and she came a few seconds after me.

I pull out my cock and we rest for five minutes. “David, help me move my stuff to your room, I’m your girlfriend now and we’re going to sleep together” she said. “Okay” I replied. I didn’t expect this outcome but I’m okay with it. “I have two other girlfriends, you don’t have a problem with it. In fact you want me to have as many girlfriends, lovers or wives as I want.” I said to her. “I’m so proud of you bro, you’re amazing, that’s why I love you.” She replied.

We start moving her things to my room. When we were about to finish moving our things mom and dad saw us and asked us what were we doing. “Sis is my girlfriend now and she wants to sleep with me, there’s nothing wrong with it.” I said to both of them and they both agreed with it and decided to help us.

I spend the rest of the day playing videogames and giving healthy fucks to mom when she asked me.

After having dinner my sister and I went to sleep.
