Charlie reaches out and grabs Sids cock. She takes Sids balls in her mouth and starts sucking as her hand runs up and down Sids shaft.

"Oh yeah, suck my balls" Sid growns. "I never thought you were so dirty Charlotte, but you seem to really like dick. I guess you're a right slut at heart. Do you like being called a Slut?"

"Uh hu", she moaned back at Sid. Suddenly she removed his balls from her mouth and asked "Can I suck on James' Cock now, Sid?"
