Very big (1400cc)

"Seems like 150cc are too small." Dr. Valentine said, pulled the breast-forms off John's chest and went back to the cupboard. As she returned, she put the next breast-forms on his chest.

John looked down and saw the bigger forms glued on his chest. They looked like beautiful breasts, around the size of his girlfriends. Seeing that caused him get a little aroused by it and his penis started to get hard in his pants.

"Still no reaction." Dr. Valentine said and pulled even this pair off the boys chest. It followed the next pair.

The breast-forms were big and round and gave John the look of having big breasts. John's penis got harder and started to create a bulge on his pants.

"750cc are still to small." Dr. Valentine said from behind John and again pulled the breast-forms off his chest.

A few seconds later she came back with the next, even bigger pair. John's pants got tight as he saw 'his' cleavage, but Dr. Valentine still wasn't satisfied. "You really love them big if 1000cc is still too small."

For the fifth time Dr. Valentine put a pair of breast-forms into the bra on John's chest. This time they were big enough to fit into the bra. John now looked down on the biggest breasts he had seen in real. It caused his pants to feel much to tight. But again Dr. Valentine didn't accepted them.

"I have one last pair." She said and removed the breast-forms.

Again she got the next pair of breast-forms. But this time she did it some other way. Instead of inserting them from behind, she walked in front of John and lightly bend over to give him a good view down her C-cup breasts.

Then she glued the breast-forms onto John's chest. She pulled the blue bra over the very big breast-forms, which caused the bra to stretch a little over them.

As she did that, Dr. Valentine also unzipped John's pants, without him noticing.

The sudden freedom, the beautiful cleavage of Dr. Valentine and the huge breasts on his chest caused John to explode. The cum shot out of his fully erect dick and didn't seem to stop. It all splashed on his therapist, which got literally showered in cum.

"Seems like we found the right size." Dr. Valentine said after John stopped cumming, his cum flowing down her face onto her breasts in thick streams. "Astonishing 1400cc."
