"An ex-boyfriend."

Nikki's suggestion takes you by surprise, and Katie too. "Really?" Your girlfriend asks.

But it's not necessarily a turn-off. You think you know where she's going with this.

"You have an ex that you don't like, right?" Nikki asks.

"Yyyyeah. From a long time ago." Katie answers cautiously.

"And he probably wished you did this sort of thing, right?" Nikki says, her wide cheshire-like smile growing.

"Uh, probably." Katie bites her lip. She suddenly realizes where this is going too.

But apparently the next part isn't for your ears. Or maybe just not for the camera. Nikki leans in and whispers into Katie's ear. You see your girlfriend's expression go from contemplative to uncertain, to naughty, to disbelieving, all in a few seconds.

Nikki leans back, done whispering. "What do you think?"

Katie's smile is big but still tentative now. "Well... I guess... okay." She turns her face and looks directly into the camera. "Hi Greg. Look what I do now."

And both girls lean in, one on either side of your cock, and lick the entire shaft up from base to tip, one tongue on the left of your member, one of the right. A strand of saliva draws itself from the tip of your cock back to Nikki's lips, and Katie, catching sight of this leans over and gives it a lick.

It's all unbelievable. Poor Greg. Lucky you.

"Okay, now your turn." Katie says, clearly feeling more comfortable. "Let's make one of your exes uncomfortable."

Nikki lets out a single chuckle. "I've done this with most of my exes. Seeing me do it wouldn't really make them jealous."

"Oh." Katie says, contorting her face into an adorable look of disconcerted uncertainty. "Well there must be something. There must be something that one shitty ex boyfriend wanted you to do that you said no to."

"Well..." Nikki suddenly seems the uncertain one.

"Let's do it!" And Katie seems up for anything, like she's finally broken through her nerves and now just wants to have fun.

"Well..."
