The bustiest woman he's ever seen (36K-cup)

"Gross." John tried to avoid the question.

"Just answer. Is she pretty?"

"I guess," John shrugged reluctantly.

"What color hair does she have?"

"Black"

"Does she have large breasts?"

"..."

"John? Are her breasts large?"

"Yes"

"How large?"

"Very"

"Larger than mine?" She pushed her chest out and showed off her cleavage, causing John to grow fully erect again.

"Yes." John gawked.

"Wow, she must really have big breasts than. I'm a D-cup on a good day."

John just shrugged.

"Do you know what cup size she is?"

"..."

"You do don't you?"

"Yes."

"How do you know what her cup size is?"

"I'm not a perv or anything. I just noticed it when I was doing the laundry!"

"Uh huh. 'noticed it'" She nodded. "Well what size are they?"

"36-K"

"36-K?" She laughed. "John why are you lying to me?"

"What? I'm not" John protested.

"John they don't make bras that big. Do you think it would make finding your mom attractive more forgivable if her breasts were cartoonishly big?"

"What? No. And I'm not attracted to her."

"Then why are you lying about her breast size!"

"I'm not! Look I'll prove it!" John reached into his pocket and brought out his phone. He opened up his mom's contact page and showed the doctor her profile picture.

"Wow" Dr. Valentine said.

"See? I'm not making it up."

"Well they certainly are huge, but I don't know about K-cup-"

"Look at this one." John said taking his phone and swiping to another picture.

"Oh my goodness! Those are the biggest breasts I've ever seen!"

"Told you so" John said smugly.

"I can certainly see why you would be attracted to her. She's gorgeous."

"I'm not!"

"John, we've been talking about your mother's breasts and you've only gotten harder."

"Not from her though! From you!" John admitted and instantly blushed.

"Come on now John, My breasts are good," She said cupping and squeezing her breasts. "But they're not that good." She pointed to the phone. "Plus, why would a son have pictures that featured his mom's breasts saved in his phone?"

"It's not like that! They're just normal pictures of her. It's not my fault her boobs don't fit into any of her clothes! She's always complaining about that."

"Of course it's not your fault. None of this is."

"You're making it sound weird though. We just have a normal mother son relationship."

"I would be very interested in exploring that with the both of you. Would you mind if we did a family session next week? Don't worry, I won't tell her anything that happened in here, that's strictly confidential."

"Sure I guess. Just so you can see how normal we are."

"Great! Same time next week then."

"Okay." John started to put away his hard cock.

"Wait, you need to take care of that before you go."

"Really?" John was horny but all this talk of his mom was weirding him out.

"I need you to ejaculate as much as possible remember?"

"I just don't think I'm in the mood."

"You clearly are" She pointed to his erection. "Would it help if you looked at my breasts?"

"Yes" John answered instantly. He started working his shaft as Dr. Valentine leaned forward and shimmied her breasts.

"You like looking at breasts while you masturbate?"

"Yes" John gasped as he jerked faster and faster.

"You like watching them bounce and jiggle?"

"God yes" John groaned.

"Are you imagining these breasts wrapping around your penis, sliding up and down over it?"

"Fuck!" John bucked. Dr. Valentine noticed the signs of his imminent orgasm and smirked to herself.

"It's no wonder why a man whose mother is so busty has such a breast obsession."

"No!" John said frantically.

"I mean just look at these" She holds his phone up to him and shoves the picture of his mom's breasts right in his face. That's when the first shot of cum escaped his dick. "Of course anyone who got to suck on these as a child would become obsessed with big breasts." John continued to stroke in spite of himself as he flung his cum everywhere. "What man wouldn't want to suck on those?"

"Why?" John whimpers to himself as his orgasm comes to an end.

"Very good John. Now remember, I want you to masturbate as much as you can today, Okay?"

John just nodded.

"Great, see you next week then.
