They do. You eat her out.

"FUCK...OHGOD...don't stop now John..." Sarah moans as you part her legs and place your head between them, running your tongue up and down her slick pussy lips.

"UH," she softly purrs as you slide your tongue between her tight folds, knowing that you'd be sliding something inside of her later on.

"I wish you'd let me fuck this pussy baby," you tell her, knowing full well that was your intention anyway as you start to dart your tongue in and out of her, her back arching as she throws her head back.

"I...can't...let...you...do...that...only...my...husband...gets...to...do...that..." she purrs, gritting her teeth as she rocks her hips back and forth around your tongue as it slides in and out of her.

"OHGOD...cumming..." she softly hisses as she throws her head back, her eyes rolling back in her head as she shoots her cum all over your face, going limp as you quickly drink them down and back your tongue out of her pussy.

And just as quickly, you parted her legs again and slid your dick into her, her back arching to send you deeper into her as you start thrusting into her.
