Emma wants you to join her and Mason

"Please, John, will you fuck me with Mason?" Emma looks **** as she pleads. "I think two cocks is what I need."

Mason's eyes go wide as he hears Emma's question to you. They go even wider when he sees you nod back to her.

"Thank you so much, John!" Emma jumps back to her feet and gives you a big kiss. You vaguely wonder if she had recently had these lips around Mason's cock.

Emma skips back over to Mason who is still sitting on the sofa - she throws the pillow he's been covering himself aside and gives his dick a few tugs before climbing on top of him and sliding back down on his already hard again cock. This time she's facing away from him.

"Come on John, take your clothes off and get your dick down my fucking throat already." You can't believe this is how Emma talks now. You never would have imagined the Slave4U having such an impact on your rather timid girlfriend. You realize doubling the dosage might have been a terrible idea.
