Plank

It's better to err on the side of caution and you feel like you're on a roll so you lift yourself up into a planking position. Between Gwyneth's thighs she gives you a smile, then relaxes.

"Continue," she moans.You keep licking away, honing in on her clit now. Every now and then she moans a soft order telling you to do a push-up or a plank but she's really leaning into what you're doing. Your tongue starts to get tired as you lick, poke, stroke, flick and even trace letters around the top of her vagina. You push on until you feel her start to shake.

"Keep going, keep going, don't you dare stop!"

You follow your trainer's instructions and keep your face buried and tongue busy on Gwyneth's cunt. Suddenly her legs wrap around your head and she shudders, crying out in ecstasy. Even as her grip tightens you don't let up, pushing Gwyneth all through her orgasmic high. After what feels like an eternity you start to let up and her grip loosens. She looks at you with something approaching warmth.

"You got me off, how do we get you off?"
