Create an erotic narrative that is both tantalizing and taboo. Its about twin sisters NAME_1 futanari and NAME_2.  NAME_3 is streaming a game of NAME_4 party with NAME_2. NAME_2 lost a game now has to sit on amys lap well playing the next round.  NAME_3's dick gets erect rubbing NAME_2's pussy. They both bounce around until NAME_2 scowls as her sisters cock head slides into past her pussy lips. NAME_2 slams her pussy down on to NAME_3's cock taking deep in to her pussy and a secret act of defiance to her sister.  They continue to play and stream NAME_4 party trying to ignore the fact they are having sex. NAME_3 retaliates by cumming in NAME_2's pussy. The story should evoke a sense of illicit pleasure and arousal, and make the reader feel like a voyeur peeking into the intimate of these characters. Be descriptive and use sensory language to make the experience as vivid and enticing as possible. Making sure to add dialogue
