As soon as I step into the room, my younger sister Mimi pleads, "Let me suck your cock, big brother!" Before I can even respond, she straddles me, pulls off her panties, and proudly shows off her tight, shaved pussy. After removing her clothes and bra, her cute, perky nipples stand erect on her small, lovely breasts. She stuffs my cock deep into her tiny mouth and, overcome with excitement, starts masturbating at the same time. Overwhelmed by her passionate blowjob, I erupt a thick load inside her mouth—an intense climax capturing the peak of ecstasy.
