Dipper had just finished another mystery hunt alone he was looking for a rare flower but could not find it. He walked upstairs to the attic which he shared with his sister,Mabel. He open the door,forgetting to knock, he saw his sister taking off her sweater, He blushed when he saw her bra and slowly back out of the room. As he was doing so he tripped onto the floor and this caused Mabel to turn around to find her brother on the floor. She blushed when she saw him and quickly put back on her sweater and Dipper got up and ran out the room. Closing the door behind him and slid down on to the floor.
He sat there thinking about how embarrassing that was and then new kind of thought entered his mind begin to think how cute Mabel's bra. He tried to shake away these thoughts about Mabel but they would not go away. He then heard Mabel's voice from the other side of the door."Dipper,Come in here we need to talk."she said nervously. Dipper stood up and walks into the room and sees the whole time he had been thinking she changed her clothes.
She was sitting on her bed and she patted the spot next to her for him to sit down. He sits down next to her and Mabel looks away from him blushing. "Mabel, I'm sorry I forgot to knock."He said while blushing red as a tomato. Mabel look in his eyes and she looked even more nervous."It's okay..but .."She paused and this confused Dipper."But what.." He asked looking her directly in her eyes."Did like you like what you had seen?"she asked. Dipper by this point blushing so red that you think that he would have a nose bleed by now.
Their was a long silence until finally Dipper spoke up."Y-yea,I liked the way your breasts looked in your bra."He said while covering his face. Mabel was blushing as much as he was ,this was always uneasy about her body but did not let get to her until now,having her brother see her like that was kind of weird but also loved the way Dipper looked in his boxer,he didn't have six pack but he was still hot to her."Thanks."She said while removing Dipper's hands from his face.
Mabel smiled at him and kissed his cheek."Uh..Mabel can I tell you something?"Dipper asked look directly in her eyes again."Sure,what?"she replied as she looked into his eyes."I love you,Mabel"He said while he looked at her lovingly."I love you too,Bro-bro" She said as look at him lovingly.
