Before Nadia, Jean and the Gratan trio entered into the Nautilus life, a particular behavior existed among the submarine crew.
The first-officer Electra is in love with Captain Nemo but the man doesn't let his feelings dominate his life's goal: stop Gargoyle's foolish crimes once and for all.
Considering the tense life onboard of the Nautilus submarine and the relationship established between the whole crew in that very peculiar situation (two females in a crew of a many dozens males), it is normal for a woman to succumb to her instincts.
Since Electra's heart belongs to her Captain, she only wanks some of the crew once in a while. Doing so, she preserves her body for her beloved Nemo and at the same time she pleases herself a little.
But the rumors of the first-officer handjobs spread among the submarine and someone decided to organize a group session with the blonde girl. Electra, flattered and aroused by this group attention, kneel down happy to receive her comrades' affection.
