Sisters come first

"Nah, Kat. You're the most important and sexy girl for me. Maybe later..." He loved Kat, even if he was taking sexual advantage of her. Besides, she still had a couple of 'cherries' he hadn't popped. Images of a sisterly blowjob fought with speculation as to what it would feel like to cram his hardened cock up her tight little bottom.

"I love you, too! Now that you've taken care of my hymen, you want to try fucking my other virgin holes? This is even more fun than I'd hoped it would be. Can I suck your cock 'til the juice fills my nasty little mouth?" The image returned him to rocky hardness, and his sister displayed a knowing, yet somehow still innocent, grin, as she reached forward and thrust her head down upon its meaty length.

It was incredible. She barely paused when his glans bumped against the back of his throat, but continued downward, until he could feel it throbbing in her throat. Deep-throat on hypnotic command! This was truly every man's dream come true. His hot little sister grinned around his penis, and maintained eye contact as she slowly let his fleshy sword emerge from the scabbard of her mouth. As a memory flitted through his brain, she mouthed the tip (just the way he remembered from a porno he'd seen a few months ago at a friend's house) and then sank her head down again, still eyeing him with an eagerness to please that kept him hard more than anything else could. She repeated the strokes, each time plunging all the way down to his pubic thatch, then sliding up to lip and tongue his cockhead with a hot smile. As she got more practice, she raised the ante by adding a selection of gulping and lipsmacking sounds that made her sound like the greediest little slut of a whore he could possibly imagine!

He could take only so much of this bliss. As he approached climax, he envisioned her coming up to drink from his cock like drinking from a hose. She rose up to do so, gulping and sucking like the juice from his pecker was the only thing that could keep her alive. "Yes," she burst out, "give me all that hot cum, brother! Little sister needs your cockjuice in her suckhole, too!" She hurriedly thrust her head back onto the cock, tongue lashing about in search of any stray morsels of jizzum.

"That's the best thing I ever tasted, big bro! We've gotta do this more often." She grinned, obviously proud of the slutty yet beautiful picture she made. "Now, how soon can you buttfuck me? Or is it time to call Cheryl in to help?"
