The unexpected incest <unk> the second part of an adventure

Hello everyone, this is the second part of the real story of how I became a very loving stepfather.
Well, after the bath and the white underwear put on, I went to Silvana's apartment for coffee, I rang the bell and soon she appeared at the door only in her underwear and nothing more, she greeted me with a cheeky smile and then hugged me and kissed me, Silvana is short, so when I hugged her, I pulled her from the floor holding her by the waist to kiss her better. After entering her apartment, she asked to sit on the sofa and went to the kitchen, I asked about her children and she said that they were still in bed, but that as soon as they left the room, I was already very excited with the kiss and with her wearing only and such sound underwear, something that I later found to be completely natural among the three in that apartment.
My heart was racing, the urge was to go into the room and grab Sophia and shove my big dick into her little mouth, but I usually waited as if I wasn't with my almost completely hard dick being forced into the tight panties I was wearing.
It was then that the young people left the (only) room of the apartment they share with Silvana. Sophia was in white panties and a pink silk top (emphasizing the flattened and curvilinear belly), just behind her brother Diego in samba underwear bail, (my "sharer" of the kiss of his beloved and crazy mother).
When they saw me, they opened a big smile, especially Sophia who in seconds was already looking at my white underwear seeing the raised volume, they said good morning to me, they went to Silvana who was clearing the table, they gave good morning kisses (seals again) and came to sit with me, the atmosphere was of pure excitement, but, perhaps because she was shy, she did not try anything, Sophia sat next to me, practically half naked, a nymph I had never imagined, sitting with those intimate costumes next to me asking in the most natural way in the world how the night of sex with her mother had been, so I answered, even embarrassed in the most natural way possible.
I: - Your mother is a delight, I've never been with a woman as hot as her. (I told Sophia who opened a beautiful smile)
Diego: - We heard you at the door, you seemed to be having a lot of fun.
It was the first sentence of my future stepson to me, after the night of sex, and, it seemed very natural that he confess that they were really listening to us fuck.
Diego: - Well, we heard the beginning, it aroused our will and we went home... (comment made looking at his
Naughty little twin sister who opened an even more naughty smile to her brother)
Finally the coffee was ready and Silvana called us, we all sat down at the table, we had breakfast like a normal "family", we talked about what good things to do on Sundays in the city and I invited them to go to a big very famous water park in the city, everyone was very happy with the invitation.
After coffee, Silvana asked the children what they thought of my size, Sophia realized that Silvana was referring to the volume marked on my underwear and said:
- He's a great mom, but he seems to be ashamed...
I realized that the conversation was about sex and my "tool" was the subject, so I took courage and after the atmosphere became more relaxed over coffee, I answered Sophia.
Me: - If you want to end my shame you know what you have to do Sophia... (I said this staring at Sophia and opening a wide smile).
Sophia looked at her mother, probably looking for a look of approval, and with a wink from my Silvana, she gets up and comes to my side that realizing what was going to happen, I stood up. She all tiny like her mother, raised her neck to be kissed, but I demonstrating to be more dominant I took her with my left hand under her butt and raised her to my height so that our kiss finally happened ...
After our first kiss, I put her back on the floor and put her delicate white hand on my dick, still above my panties. Sophia, realizing that it was too hard and turned to the side being crushed by the panties, then lowered my panties revealing my thick pussy. She looked scared at Silvana, "slamming my hard dick" and alternating between looks at her mother and my roll. Then I took a step back and by grabbing her hair the same way I had done 12 hours earlier with Silvana, I showed her the way from her mouth to my dick, tilting her chest.
Sophia sucked me very willingly, equally frightened by the thickness of my roll, she put as much as she could in her mouth, managing to pass her head and sucked me with pleasure, then I look at my Silvana who was glazed watching the show and Diego who looks hypnotically at his little hand sucking me without looking away or winking.
After a nice kiss from my new "bearded girl", I took her in my arms and took her to the sofa, laid her on her stomach, got down on my knees and started sucking on the pussy of my newest acquisition. I totally ignored the fact that her brother and her mother were watching us like in a porn movie, so after making me groan a lot with my tongue, still on my knees and her lying on the sofa on her stomach and legs wide open, I started the penetration which was difficult, but not as much as Silvana.
- Put your cute little mouth on, shove that giant torso of yours at me...
That's right, that's right, that's right, that's right, that's right, that's right, that's right, that's right.
It was a scene worthy of a high-quality pornographic film, me, a large, six-foot-tall man, shoving my big dick into a 17-year-old, skinny, blond, skinny, milk-white ninny.
I was putting it in slowly, waiting for her to get used to my dick, then I look back and see my first incestuous scene of my life. <unk>My<unk> Silvana was on her knees in front of the table with her son Diego who was standing with his dick out giving his mother make a delicious oral. Diego was fixing his gaze on his sister taking roll, did not look at Silvana.
It was then that I noticed that my stepson had a normal dick in length, about 15 cm, but there was a clear difference in caliber, my dick is much thicker and a little bit bigger. I was really doing damage to my stepdaughter who until now was enjoying my dick without me putting it whole and hard as I did with Silvana in our second time.
After about five minutes watching my new nymphet rolling on my dick with a face still suffering carrying my roll, I decided to take her from the front and stand holding her against my body, I put my roll again on her nipple and standing I began to fuck her holding her beautiful little body, this time with me controlling the strokes that got stronger and stronger, beating her body against mine, until I fucked hard screaming from Sophia who did not pronounce anything else with anything, just screamed while I was forcing her. She screamed that she was mocking and like her mother, had a very strong orgasm, with the body being held by me. I looked to the side and my whole being was getting into her mother's ass, Diego put her on all fours and started forcing, with Silvana carrying the arselet well and looking at our own son.
Silvana stopped for a moment, got up and took her son by the hand, came to me and told us all to go to bed. Without removing my nymphet from my <unk>colo<unk>, I took her still stuck with my roll to the room, accompanying Silvana and Diego who soon continued in a beautiful <unk>daddy and mom<unk> or would be <unk>son and mom<unk> hahahaha
I put my four-year-old nymphet on the bed and I got down on my knees on the edge, I put my little nymphet back with pleasure who was very fond of my role, she had already had two orgasms while we were in the room and I had not yet mocked. After another five minutes of pressing hard on my stepdaughter who was four receiving my jeba in her little pocket that was getting redder and redder because she was Jewish, she says:
Sophia: - Go you pauzudo, enjoy, please, I'm not holding out any more... (Sophia seemed to have less resistance than her mother)
Realizing she couldn't take it anymore, I took my stick out of her busted little mouthpiece and put it in her little mouthpiece, which was panting, trying its best to suck me so that I could finally have fun.
My nymph was panting and very satisfied, Silvana, more naughty and crazy than I could ever imagine, took a little bit of the cock from the corner of her daughter's mouth and put it in her mouth, looking at Diego who made a rabbit and then announced that she would mock, mocking intensely inside her mother as they kissed.
After Diego made fun of Sophia, we collapsed in bed, the four of us, exhausted after the first fuck of the day, and there was not a word in the room for almost five minutes until Sophia decided to break the silence.
Sophia: - Our mother, who delights her boyfriend, I'm finished, look how my pocket got... hahahahahah (showing the super red and broken pocket to Silvana)
I'm glad you liked it, Juliano told me about it yesterday.
Diego: - So now I'll have a help finally, I was no longer noticing Juliano, those two are very crazy, prepare friend, you'll get the thin stick of both fucking these whores...
I realized something at that moment that something left me with a flea behind the ear, not only was Diego happy to share his mother and sister, as he, more than them, did not stop drying my cock. He looked at my roll without disguise while caressing his own roll ... Diego also threw his gaze at me and I did not know if it was for the complicity for the four-way sex that I had just rolled or for some interest in my newest stepson skinny, blond.
After our first "family" sex, we all got dressed, got beach clothes, towels and sunscreen, and got in the car and drove to the water park.
The atmosphere was family, we talked, we exchanged experiences, we talked about everything, the trip lasted almost 1 hour (The park is located in a nearby city) and on the way a lot of things that I never imagined had been revealed to me by all of them, including that Diego also liked to be passive with his mother and sister, further reinforcing my mistrust of the looks in the bed after sex.
Keep going.
