You have ways of making her talk...

You grab Jenna's nipples, and you begin to twist them gently but insistently as you pound deep into her pussy.
"Ahhh!!!"
"I can make you talk, Jenna..." you smile, squeezing her little nubs ruthlessly.
"Ow...you brat...oh fuck..." she starts rubbing her clit as you continue to **** her tits. "Fine...."
"That's my good girl...now... who's got a crush on your husband, Jenna?" You wrap a hand gently around her throat, tilting her head back.
"Well....there's Lisa..." she offers up reluctantly.
"Lisa Simpson?" You chuckle inwardly at the name. Neither Jenna nor Lisa were really aware of The Simpsons.

Lisa is a 30 year old former stripper from Yuma and she teaches poledancing at Jenna's studio, as well as jazz and hip hop. She's been divorced for 5 years, and her ex-husband bought the 34DD boobs she flaunts around. She's a funny, earthy girl, with a ready smile and no qualms about the life she's led. You've been out to dinner and dancing with her and Jenna many times. She was always friendly, but you never imagined...
"Yeah baby. She told me once that I was a lucky woman, and that if we weren't such good friends, she'd be trying to hook up with you. I was pissed that day, let...oooh fuck...let me tell... youuuuuu...." she loses herself a little bit as you grind into her spot.
"Interesting... who else?"
Jenna's eyes are rolling.
"Jenna!" you stop pumping, and start to pull out of her throbbing hole. "Who else?"
"No...give it back...I'll tell you..." she pulls you back inside her fiercely. "Sammi."
"From the club?"
"Yeah... one night I was drunk and showed her one of your "progress" pics, you know, from your workouts. She was practically drooling."

Samantha LeTourneau, who goes by Sammi, is a girl you and Jenna met at the salsa club, two years ago. She's 26 years old, and in public relations. She's super fun and laid back, and you've danced with her many times at the club. She did seem a little... enthusiastic, sometimes, now that you think back on it.
"Is that it baby..." you pound harder, and Jenna frigs her clit furiously, cumming hard on your cock.
"....um...." she pants, and looks away.
"What?"
"I don't know if I should..."
You flip her into a kneel, sliding into her doggstyle. "Tell me, Jenna. It's best to have it out."
