After a week of traveling the crew of the Planet Express ship finaly returned from their long voyage to the Horsehead nebula to explore strange radiation that was emitting from an asteroid, Leela and Amy were sent to investigate, unfortunately they both got contaminated with albeit low levels of gamma radiation, but it was radiation none the less. They were both sent to the showers and thats when it all got interesting. While undressing Leela started to notice Amy’s curves and her beautifuly shaped breasts, she dismissed the thoughts at first thinking they were merely from jealousy. When the water started Leela kept her gaze at Amy’s breasts and watched as the water slowly streamed its way down to her pussy, Leela not having had sex in over a week starts to get realy horny realy fast, her nipples harden and her pussy gets even wetter. Amy, never to miss a chance, out of nowhere started kissing her (Leela of course not objecting), her hands which are around Leela’s hips slowly and gently start going down until they reached her drenched pussy, her fingers started rubbing her clit and slowly made their way inside her. Leela starts to subtly leat out moans and sighs and decides to return the favor. As they near climax they grip even tighter, fingering even faster as their breasts rubbing, and at the end, they both give out a moan so loud and so powerful every human in New New York be it male or female had an orgasm. They leave the shower free of contamination, and part ways with a sensual kiss.
After that their friendship was cemented, and the other members of Planet Express sware they sometimes see Leela’s hand down Amy’s and at night hear moans that would wake the dead.
