181827 - Stepsis Diaper JOI Roleplay

I really like that you came to visit me in my room, stepbro! We fell asleep together while watching movies. That's okay, it's not like we had sex. Even though we both desperately want to fuck eachother, I know it... I wake up super horny next to you and talk to you. I secretly put on a diaper when you fell asleep. I very urgently needed to poop but I held it and I masturbated a lot throughout the night. I fell asleep eventually with the huge poop log still filling my ass. That feeling of my ass being filled with such a thick wide hard log caused me to have a sex dream about you. About you fucking me in the ass, stepbro... Don't tell mom and dad! I lower the blankets and you see that I'm topless, only wearing a cute diaper.You notice how horny I am. It's making your dick really hard. I start rubbing my pussy through my diaper and tell you about my dream. I talk dirty telling how badly I need to poop and how amazing it feels. I encourage you to start stroking your big hard bulge in your pants too. I mean it's not like we're having sex, we're just touching ourselves together. Surely that's a normal innocent pastime for stepbro and stepsis. I encourage you to look at me while you stroke your hard dick. I ask you to take your hard dick out of your underpants so I can look at it better. You see the lust in my eyes as I rub my pussy harder. I suggest you follow my rhythm with your cock strokes. That feels amazing, it almost feels like we're doing it to eachother right stepbro? But we're not, so we're not doing anything wrong! It turns me on so much to look at you stroking your dick that I explode into a delicious shaking orgasm.Then I completely poop myself while moaning hard, it's a huge load! I pee on top of it too. Ohh it feels so amazing, stepbro! I'm absolutely hungry for another orgasm and start stroking my pussy again. I encourage you to jerk off more and harder with me. The poop and pee feels so warm and delicious against my body. I start rubbing my pussy really hard through my diapers and I invite you to follow my rhythm. I reassure you that we're still not having sex so it's really okay what we're doing. We're just looking at eachother while rubbing ourselves. I ask you to feel the amazing big fat warm poop and pee bulge in my diaper. I reassure you, feeling up the bulge in my dirty diaper is not having sex! So we're still following mom & dad's rules. I rub my pussy hard as we feel up my diaper bulge while you jerk off with your other hand. Let's cum together, stepbro! If you cum on my diaper, it's not sex! Then we're still a good boy and girl. Let's please cum together, I'm so close to orgasm! Oh yes, yes, yeeaaah!!! You cum hard all over my diaper as I have a shaking orgasm, desperately trying to hold in my moans so mom and dad won't hear. Ohhh stepbro, I love the games we play!
