"Is she good with her mouth?"

I ask Millie, trying to sound sensual and mature but not sure if it comes out that way.

"Very." Millie replies dreamily, looking down at Rochelle that is now sitting between us, jerking my cock. Millie stretches her arms behind her head, yawning, then says:

"Rochelle, let Matt feel what you can do with your mouth."

Rochelle shake her head, saying:

"That's a bit too personal I am afraid."

Millie lets out a little laugh, saying:

"Come on, we've known each other for a really long time."

Rochelle shakes her head, saying:

"Am not comfortable with that. He's so young, am not having an 18 year old boy's dick in my mouth."

Millie sits up and strokes Rochelle's face, saying:

"Come on, don't you like his cock?"

Rochelle does not reply, just looks down and shakes her head. Millie gets a mischevious look in her eyes and says:

"A fifty dollar tip in it for you."

Rochelle shakes her head in response.

"A hundred." Millie says.

Rochelle stops jerking my cock and looks at Millie, like she is thinking, then after a few seconds says:

"Okay."

She looks at Millie for a few more seconds, then opens her mouth and leans into my lap.
