Do a pushup, fuck a pocketpussy

It started out as an innocent favor. Your girlfriend wanted to try some new exercise fad and she needed your help to do it. You had originally planned to tag along only because you figured you could get some nice visuals of her in workout clothes, maybe even get an opportunity to fool around a bit and possibly cop a nice feel outta the whole thing. You should have realized when you arrived that she was far too giddy about exercising of all things, but you didn't. And for being such a worthless schlub you ended up bare assed naked, your arms burning & quaking as you repeatedly lift yourself up and down. You feel yourself tense up all over as she lightly brushes her fingertips over your junk and teasingly rubs the lips of a pocket pussy against you. You start to try and fuck the thing but she pulls it away just in time, she makes a point of giggling while she reminds you, ' We still got two sets of push-ups to go before you get to use the toy again!' Grunting as much from the exertion as the blue balls you (very) slowly and surely start to finish off your sets. As you near the last few you can hear her giggling again, this time telling you, 'What a good little boy, I'm so proud of you! I'm glad we're both having so much fun!' You briefly thought you disagreed, until you felt her hand slowly start to massage your balls while with her other hand she kept the fleshlight juuuuust out of reach for you to start fucking it while still close enough for you to grind against the feel of it.

Your vision starts to fade as you, over-dramatically, start to think you're going to die a virgin. But in the next instant you hear her say, 'And you did it!' Your euphoria of being able to do god knows how many push-ups is quickly surpassed  by the feeling of her squeezing your balls and slamming the pocketpussy as far down as it'll go on you. You erotically belt out a 'duuhhuh' as you buck your hips and cum inside the sextoy. She takes her time to laugh at you, while she slowly masturbates your cock with the  toy and her hand.

And while you bask in the awkward puffy afterglow of your sex-cercise experiment, you crack a smile. She's wearing blue panties.
