Butterflies in my Head 1

Dipper activates a device he got to see if it works, when he sees Mabel and Pacifica he calls them to show them the magic butterfly he got, it flies and sprays something to both of them, he apologizes and they both leave upset.

When they are both alone, Pacifica decides to go to change, but when Mabel sees her naked she cannot help but get excited, Pacifica notices it and goes with her, she touches her and kisses her, little by little both get carried away, Mabel touches Pacifica while Pacifica also stimulates her, the pleasure and lust takes over both, and they decide to continue without stopping, they stimulate, penetrate and touch each other until both can’t stand it anymore and finish.

This unites them even more, Deeper masturbates watching a picture of Pacifica, not knowing that this new relationship between his sister and the girl he likes, has been for him and the butterfly.
