Still curious

Not moving her eyes from your cock disappearing into her friend's mouth, she answered quietly, "yeah."

"Do you want to see what I would do next with Emma?"

Again quietly, "yeah."

"Emma, let's show Lily that the girl doesn't have to do all the work. Come here," you gently pulled her to her feet and stood up with her.

You pulled Emma's top over her head. You kissed her deeply while reaching around to unclasp her bra, then down to undo her pants.

You pushed Emma onto the bed and laid down between her legs. From beside you, you heard a quiet "oh my god".

Emma's pussy tasted as sweet as ever, and her wetness confirmed that this wasn't just a demonstration for her either. You settled in to enjoy her, figuring that would make for the best show.

Suddenly, you heard a scraping noise you weren't expecting. You looked over to see Lily pulling the chair toward the bed so she could get a closer look. You smiled at her, but continued giving your attention to Emma.

Emma was starting to pant, but you heard her say to Lily, "it's okay." You looked over to Lily to see her shifting in the chair, pulling her hand away from her crotch. Emma continued her encouragement, "go ahead. Guys think that's hot."

"Are you sure?"

You confirmed, "yeah, go ahead. Explore all you want while you're here." You looked up at Emma and smiled. She smiled back. Both of you were enjoying the performance.

You returned to Emma's clit, licking and sucking until she showed Lily exactly what having a good orgasm looked like. Taking a moment to glance over at Lily, you saw that her shorts had been unbuttoned, with one hand hidden inside them. Her other hand was exploring under her shirt.
