Double-duty

You weren't the only one enjoying Rosa's dancing. Lucia had made herself comfortable on the bed and was slowly working her fingers in and out of her pussy as she watched the two of you get to know each other better. Having satisfied yourself with the show so far, you wanted to move the night along.

As Rosa's dancing naturally brought to face away from you, you put your hands on her hips and stopped her. "Lean forward a bit and spread your legs." You told her. "I think you're going to like what comes next."

With that, you sat back down on the bed, further back this time, and gave Lucia her instructions. Giving you a devilish smile at hearing the upcoming surprise for her sister, Lucia quickly straddled you in reverse cowgirl. After aligning your dick properly, you quickly slid into her dripping wet pussy as she moaned in pleasure.

Putting your hand on the back of her head, you pushed her forward, reminding her of her most recent command. Keeping you lodged in her pussy, she leaned all the way forward so that she was supporting herself on outstretched hands, aligning herself perfectly to carry out her task.

Rosa gasped as she felt Lucia pull her ass cheeks apart and start licking her asshole. Rosa started groping her own tits and squeezing her nipples as she enjoyed the sensation of her sister's rim job.

"How does your sister's tongue feel back there?" You ask Rosa.

"So good, John!" She moans. "Sooo fucking goo-ahhhh!" Lucia had quietly balanced herself on only one outstretched hand, and had started fingering her sister's pussy while licking her asshole. Rosa's moaning grew louder with the increased stimulation.

"That's a good slut," you said, smacking Lucia's ass hard. "Get your sister's cunt ready for your husband's dick!"

Lucia quickly paused to let out a breathy "Thank you, Sir! I live to serve, Sir!" before returning her tongue to work on her Rosa's asshole.

After about another minute of this, you decide that its time for the main show.
