Continue to tease her about being a groupie

"Well you did look really hot when you left today, I bet all the eyes in the house were on you when you got on stage. Hell I'm surprised the band could keep playing. I bet if you weren't with me you'd have been the biggest slut on the stage." I'm surprised at how turned on I'm getting, hard cock in hand.

"You're really getting turned on by this aren't you? Your innocent girlfriend being a slut for a band? Dancing on stage flashing everyone my tits." I can hear how horny she is in her voice.

"Why don't you find someplace private so you can play with your pussy?" I offer as a suggestion. There's a moment of silence.

"Yeah private so you can really hear it" She had this evil tone in her voice and I knew I was in for a good time tonight. I heard some shuffling around then after a minute or two she was back "Alright this groupie is ready to get fucked by the band." She sounded very determined when she said this. "Being the good slut I am I didn't wear any panties under this skirt all I needed to do was hike it up and the band could see how wet my pussy is for them and ready to use me" She moans into the phone "I've been eyeing up the lead singer all night I could see his bulge and tell he had a really big cock. He's got it out and is ready to sink it in me and make me his groupie."

Then she let out this gasp, "fuck fuck fuck fuck oh god so big" She whispered in the phone. "I bet you love that big cock you slutty groupie." I throw at her as I'm fervently stroking my stiff cock. All I hear for awhile is moans. "I'm such a dirty groupie next time I should just let them fuck me on stage."

I let out a low moan at the thought of this, my rock hard cock is already twitching from excitement. Suddenly her moans are getting louder and I can tell she's about to cum. I time my shot right as you hear her hit her peak, shooting all over my chest.

"God that was amazing," I tell her trying to catch my breath. She lets out a little giggle on the other end.

"I'm glad you liked it, now I'm going to let you go and be a good groupie and fuck the rest of the band. I think Jason deserves a reward for taking me too." Before I can respond she hangs up the phone. I'm surprised that turned me on as much as it did and how good of a actress she is. It sounded like she was really getting fucked hard and she never dropped character. I clean up before heading to bed to pass out.
