You woke up or at least felt like you were awake. All you could hear is the fleshy walls of your sister breasts moving as if it were breathing. It was dark but warm, plus you were able to breathe just fine. You noticed that you were no longer moving as it appeared that nothing was pushing you except for a weird compression on your crotch. You could have came but you felt exhausted as if the life was sucked out of you. It appeared that you were cumming as you slept...what was even weirder was that you could not stop thinking about Rose. This was so wrong much less impossible...yet so right...

"Nick...Nick...Nick..." you heard your sister mumble in her sleep. There was no doubt that you and your sister had a good relationship but now it had gotten deeper...quite literally. You sighed and tried to possibly go back to sleep...however it was a little difficult now that you could hear your sister's heart thumping. In fact, it was quickly increasing as well as the mumbling in your sister's voice.

"Nick...Nick...Oh Nick...I love you...I....Nick!" her mumbling quickly turned into moaning as she dreamed about you. Her breasts and whole body started rumbling. You felt like being in a earthquake with all the shaking!!

"Aaaah!" she cried cumming herself on her bed. In the moment of pleasure, she sat up giving her breasts and you a nice shake.
"Oh my god...I fell asleep!" she gasped and looked at the time. She looked all over her bed and grumbled.
"I can't believe I came like that! Where's...Nick?" she looked over to the other half of her bed. It looked like she had forgotten that she had taken her little brother into her very own being, that said, her breasts.
She looked into the mirror and saw her naked self. She gasped as she saw her enormous breasts that held you. She remembered what happened and quivered a little. The only thing that was different was that both of her breasts were equal mass. She wondered what happened to Nick insider of there.
"N-nick? You're big sis is awake...are you okay?"
