With my sister...

We couldn't stop kissing with so much tongue and saliva. It had been minutes since we were taking mate in the kitchen with my sister, and now we were standing next to my bed, she only wearing her underwear (still), and I fully dressed. As I could, I finished taking off her bra and fondling her giant tits and huge ass, acknowledging that I didn't have enough hands to fondle her, and while we were kissing, I pinched and stretched her nipples, but this only made her moan and get hotter with each kiss we gave each other. I: You're killing me... I'm so wet! I think she didn't finish saying that, which was like a green light for me. I put my hand through her leggings and thong, and could feel her totally shaved and wet pussy. Without hesitation, I easily found her clitoris because it was well lubricated, and I grasped it with my index and major fingers, feeling myself getting filled with fluid the rest of my hand. When I finally put two fingers directly inside her, she didn't make me wait. I: You're a son of a slut! How hot you are! I need to suck your cock now, I don't want to imagine it anymore... Come on, girl, take off your clothes! I unbuckled my pants and hadn't finished taking off my shirt when she herself pulled down my boxer briefs so she could put my cock in her mouth. I couldn't believe what I was seeing and feeling. While she was sucking me whole until she almost choked, she looked at me with tears in her eyes. And only took it out of her mouth to pass her tongue along it. I: Mmmmm yes... This is herma.. (and I stopped myself from saying hermana). She realized it and says: Do you like your little sister sucking your cock like this? I: Yes, Isabel... I love it... You're killing me. I: No, Isabel, no, I'm your sister... The slut with whom you always wanted to be, since she was a sweet girl. Do you want your sister to suck your balls? I could only nod my head, and my sister started putting one of my testicles in her mouth. sucking me off, causing a mix of pleasure and pain at the same time. With my balls inside her mouth, I could feel her tongue... And I'd pull them out full of saliva. Me: I want to fuck you already!... I: Do it! Fuck your sister already... I need to feel your cock deep inside. I threw her on the bed and quickly pulled down her leggings. She opened her legs instantly, and I could see a small thong being devoured by my sister's fat pussy... Her lips were sticking out from the sides of the tiny fabric. I couldn't resist, so I ripped the thong to one side and dove into that terrible fat pussy, totally soaked. Ah, there it was, hard like before, her clitoris well red, big, like a bell. I didn't hesitate and started licking her cavity, noticing how she opened up more and more as my tongue passed between her lips. And with each lick, I could feel her flavor, sometimes sweet and sometimes sour. From my nose to my dick were totally soaked by my sister's juices, and she was twisting in pleasure. At one moment, we both made eye contact, it was wonderful, it was sex, passion, lust, morbidness, love. The whole mix of sensations went through our bodies. With a quick movement, I stopped licking her lips to focus only on her clitoris. I gripped it between my lips and then did it gently with my teeth... Meanwhile, I lied, first one finger and then two, in my sister's pussy. Me: Please... Put your cock in me already, I'm not going anymore!! Fuck me, fuck me already... I got up just to put my cock in her while seeing her play with her tits, pinching her nipples and moaning, waiting for her reward. In one go, I put my cock in Isabel's pussy. It was incredible the feeling of doing something so desired by both of us and so forbidden. Me: Ahhhhhgg, my love, how you're fucking me. You have such a beautiful cock, please! And: Ahhhh... All for you, slut... Did you want your own brother to screw you like this? - Siiiii... like this... keep going, don't stop. The moans turned into both of our cries, into insulting shouts for the two of us. For a moment I swear I thought about what would happen if my wife came into the room at that moment. And just thinking about it got me hotter, and my cock got harder. My sister knew or incredibly seemed to intuit it because she said: - Do you screw my sister-in-law here? - No, my love... You're going to screw yourself alone, beautiful girl. - Don't say it like that, you're going to make me come already.. - That's what I want, little sister, finish me off completely! The more we talked, the higher the stakes got for each of us. My orgasm was imminent and I let her know: - Ahhh... I'm done, Isa... I'm about to cum. - Do it, call out my name. Let's come together.... Fill me now . - Ahhhhhgg... here it goes... Take it, take it... First two and then a third shot of my cum came out with force inside my sister... - Ahhh, Ahhhhh.... You're so hot right now. She was saying to me. We slowly brought the pace down... And the frenzy gave way to caresses, complicit glances, and kisses.. We couldn't believe what we had done. Both of us knew that this was just the beginning.
