Speed up, go down

You navigate the blonde backwards onto a bench, and she awkwardly falls straddling it. You lean in after her, your face landing squarely between her thighs, your tongue slipping swiftly between her slippery lips, finding its way right inside her.

She pushes your shoulders away, kissing you briefly, her own juices smearing across her face as she shoves you back, "No, you first!" She rolls down, her lips meeting your other pair, returning the favor with vigor.

You hadn't realized how far along you were, or maybe hadn't expected her to be so good, but it seems like her very first touch had you gasping for breath. You're crying out in under a minute as her tongue and fingers work their magic, your eyes flirting closed in ecstasy.

"OMG!" A lilty voice comes in your ear as you hear a phone click a picture, your face, gasping for breath, suddenly bathed in light.

"Selfie with orgasm girl! Hash tag just another day at the gym!" You open your eyes to some young blonde, must be no more than 18, tapping away at her phone.

"Ugn!" You manage as the nearly-as-aggravating blonde between your thighs refuses to relent.

"Ooh! I've got to get a vine of this!" A black haired girl leans in next to you with her phone up, "Sally, get in the shot with me! Big smiles, thumbs up!"

The blonde pulls in on the other side and the black haired girl taps the phone to record. You open your mouth to protest, but all that comes out is "oh god oh god oh god I'm cumming oh god" over and over.
