YAL-024 Is it okay to show my beloved brother my creampie sex without hiding the whole story...?

My sister, Iku, has a friendly, sweet personality... I never imagined things would turn out like that. She's appeared in adult videos under a different name, but her sweet personality remains intact as she passionately kisses other men. She picks up my dick and gives me a slow titjob, then licks my pussy in a 69 position, letting out cute cries of pleasure as she orgasms. She sways obscenely in cowgirl position, the sound of our genitals colliding in the station-style position reverberates throughout the room, and she soaks the sheets with her squirting and pussy-fucking during doggy style, gazing at me with satisfied eyes after I cum inside her. Tsugumi, who's never fought with me since we were little and always listens to what I say... I'm furious that she's doing something like this, but more than anything, I'm excited. The Tsugumi I'm looking at is a Tsugumi I don't know, who stains her panties just from having her nipples played with, and who looks up as she takes my dick in her mouth and sucks my balls, drooling. She squirted multiple times while fucked from behind, and even in missionary position, my dick was inserted so deep inside her that it was hidden, causing her juices to squeeze out and cling to my dick, and I ejaculated into her, her hips still trembling even after we had creampie sex.
