Lena’s big day: A story of boobs and expansion [m/f] [fantasy]

Just yesterday, a young girl named Lena had experienced breast expansion for the first time. She always wanted such a thing to come true but knew it couldn't happen before now. She loved the feeling and the amount of rapid milk production that caused her expansion, but today is a different day. Her boyfriend is in for a pleasant surprise, and so is lena.

It was only the next day that things really got crazy for Lena. Her boyfriend Joel, who had knocked on her door shortly after her dilemma, had entered and saw her lying on her bed with her breasts resting over her arms. They were still leaking some milk, but they seemed to have calmed down since they last acted up.

Joel walks over to her bed, sits next to her on a chair and asks "Lena? What happened here? Why is the bed soaked?"

She looked at Joel and replied "Ah…Joel. My breasts were doing something earlier. Something that might be hard to believe…" Joel looked at her with a concerned look and said "You can tell me anything. You love me don't you? I won't tell anyone else. But why are you're breasts far bigger than before?" Lena then told him everything that happened, and Joel was quite surprised. "So, is there anything i can do to help y-" Just then, Lena's breasts began pulsing and making stretching noises as she said "Ohh no…again? Ahh~ Joel-"
