John laughed, this wasn't getting them anywhere.

“Come here," he commanded, holding his arms open in a clear invitation for her to sit in his lap.

Alyssa got up and then sat down obediently, still not understanding the situation.

John reached around the confused girl and cupped her round, firm breasts. This evoked a contented sigh from the teenager as she enjoyed his tender touch.

“Look at the pictures again, honey,“ he whispered in her ear, as he gently squeezed the taut flesh of her pert chest.

“Which of those girls has delicious breasts just like these?"

John watched the girl's face as shocked understanding hit her suddenly.

“Holy fuck!!!" she profaned animatedly, as she leapt to her feet, her hands moving up to cup her own breasts. The shocked girl gawked at the proud tits filling her hands and then back at the image on the screen.

“What... I... How is this possible?!" she gasped.

“I'm not sure," John replied honestly.

“I've never seen or heard of anything like this before."

Alyssa seemed to be trying to look at the monitor and examine her body at the same time, a look of stunned disbelief on her face. He waited patiently and let her acclimatise to her ravishing new form.

The Lovely teenager eventually sat down demurely in the co-pilots chair her head tilted to the side as she scrutinised the two images in front of her. He could almost see her mind whirring as she processed this change.

"You said you had never had any long term girlfriends before?" she asked directly.

“Were they all one night stands?"

John nodded tentatively. "Yes. With my unusual parentage, I figured it was probably for the best," he answered, repeating his earlier explanation.

“So you've never fed this amount of your cum to a girl before?" Alyssa probed him pointedly.

“No, never," he confirmed.

Alyssa sat, studying him shrewdly for a few minutes, her mind turning over possibilities, constructing theories. Eventually she seemed to make her mind up on something and a big beaming smile formed on her luscious Lips.

“Well thanks for choosing me as your test subject!" she giggled cutely.

John Laughed along with her. "You're welcum!" he joked, eliciting peals of laughter from the girl.

She came over to him and kissed him soundly. "I mean it John. Ever since I was a little girl I wanted boobs, and it looked like I was never going to get them," she said as she hefted her impressive rack in both hands.
