Legal/ Lead her to the stalls
You take her by the hand. "Why don't we find somewhere a tiny bit more private?" she says as she leads you to the back stalls. She pulls you into the open booth and locks the door. "Okay, do it again. Make it perfect." You close your eyes and envision your cock as she described. When you open them you see her already fully nude and on her knees, marveling at your magical dick. "Oh, you must get all the ladies and lolis with this." she says as she grabs it and works it around. "Y'know i've never been able to deep throat my husband much to his disappointment. Do you mind maybe shrinking it just a smidge?" You shrink it down to 7 inches. "Perfect." and with that she takes you in her mouth. This woman knows how to suck a cock, she is swirling her tongue around while providing the perfect suction on it and is even going all the way down on it. She's more of a pro than she thinks, so you decide to show her what she's really capable of.
Once your cock is all the way in her and her nose is buried in your pubes you grab her head and hold it there. You grabs you by the waist and instead of pushing away she tries to push you further in. You grow your dick back to the size it was and feel her throat get tighter as your cock goes deeper until she starts to cough and gag at which point you shrink it again. Once she catches her breath you grow it again until it makes her gag then shrink it. Again and again. Until you grow it and she doesn't. You hear and feel her moan excitedly at this as she starts rubbing her pussy which has already formed a small puddle on the floor between her creamy thighs. You pull it out until only the head is in her mouth then slide it back in all the way. Still no gagging. Her eyes look up at you and you can see the joy and excitement in them as she finally can deepthroat a big fat cock like she's always wanted to.
You pull it all the way out and she is smiling and moaning, so distracted by the excitement of her accomplishment and her fingers in her pussy that she hasn't even closed her mouth yet. Drool dripping off of her mouth and onto those perfect natural MILF tits. "Oh my fucking GOD! That was...was...ohhhhh....." she tries to speak but is so caught up in her orgasm that she almost goes limp. After she spends a few seconds recovering and becoming aware of her surroundings she stands up and passionately starts kissing you. You grab her by her legs and carry her as she wraps herself around you embracing you close and tight. You feel her hard nipples poking at your chest and her pussy juice running down your stomach and onto your dick. You manage to get her tongue out your mouth long enough for her to talk. "You're amazing! You just saved my marriage! How can I repay you?!"
