The girls continue to explore

Riley broke the silence and judged, "that was fucking hot!"

Zoe, still a little stunned by what she had just accomplished, quietly agreed, "uh-huh".

Riley looked down at David's cum starting to drip out of Zoe. She then looked at Ashley and suggested, "if you like cum so much, there's some right there you could have."

Ashley looked wide-eyed at Zoe's pussy, then up to make eye contact with her, wordlessly asking what she thought of the suggestion.

Equally wide-eyed, Zoe looked back and nodded excitedly.

David wrapped his arms around Riley as they watched Ashley nervously crawl between Zoe's legs. Their nerves evaporated when Ashley moaned out a quiet "mmm" and Zoe sighed happily at the sensation of her friend's tongue on her pussy.

He whispered in Riley's ear, "good suggestion." She pressed herself against him as she watched her friends discover new exciting sensations.

With them distracted, Vicky took charge again. She looked at Mia while whispering to Sophia, "she liked it when Riley licked her. Do you want to try?"

She answered tentatively, "oh... okay."

"I'll show you what to do."

Vicky guided an unresisting Sophia between Mia's legs and started her demonstration.

David squeezed Riley, "I guess it's just us, then."

She pivoted in his arms to face him and stretched up, kissing him deeply.

Their four guests continued to explore together, with enthusiastic help from Vicky, Riley, and David until they took a break, slightly worn out from their activities.

As they lounged in the expansive bedroom, David heard the apartment door open. The noise level increased as Sarah, Amy, Julia, and Maria returned from their night out at The Beaver Hole.
