Scott wiggled his firm ass back and forth when Bella squeezed it.  He pulled out of Emma and put his hand down between his legs.  He grabbed hold of his shaft and pushed the underside of it against Emma's slit.  He rocked his hips back and forth, grinding himself against her body.  He watched Bella's and Emma's tongues wrestle each other between their lips and happily joined in when Bella pulled him.  He first kissed Bella, and then Emma before pulling back.  He continued to tease her though as he watched.  His eyes full of lust.
