Dipper and Bill are now married and live in Gravity Falls with their twin kids, Michelle and Orion. Both were putting their kids to sleep.

"Dad, can you tell us a story? Please~" Michelle asked with puppy dog eyes.

Bill shook his head "Not tonight sweetie, maybe tomorrow" He kissed her forehead and Orions, He turned off the light and closed the door. Tonight, Him and Dipper were going to do 'Mommy and Daddy Stuff'.

Bill smirked "This should be fun" He whispered as he began walking down the hallway and to their room, He opened the door and saw Dipper lying a seductive pose and smirking. Bill grinned and closed the door and locked it.

"Kids are asleep?" Bill nodded, Dipper got up and sat on his feet. Bill was in front of him.

"Good, now we can have Parent Time" Dipper purred.

"I like this Dipper" Bill said huskily. Dipper lied down and Bill on top. Both leaned in and kissed passionately, Dipper arched his back, both of their erections rubbing making Bill groan in the brunettes mouth. Dipper did it again, making Bill moan.

"Nngh...."Bill moaned, Bill separated from the brunette, trailing kisses over his body, he licked one of Dipper's nipples, Dipper bucked his hips and moaned.

"Oh Goddddddd!" Bill leaned in and sucked, bit and licked his nipples, pleasure racking all over the sweaty brunette. Bill in unlatched from the brunette, taking in the sweat, Lust filled his eyes, sweat glistening his skin as his hair stuck to his forehead. He kissed him again, he went to his neck, he bit down on the brunettes neck, Dipper moaned in pain but was already adjusting to it. He lapped up the blood oozing out of it.

"I'm ready to go further~

"Mommy! Daddy!" Bill and Dipper groaned, the kids always interrupted when they were about to go further. Dipper looked at Bill.

"We'll finish this later, I promise"

"Mommy!"

"Coming!"

Bill sighed "Sadly I'm not"
