Once upon a time, in a town near a desert, lived a pure young woman named Lilith. She was Adam's wife and she was the nicest and purest person in town. Lilith never had sex with anyone other than Adam. Adam was an extremely jealous person, but even if he weren't, Lilith still would have remained loyal. Meanwhile, Adam was always cheating on her, banging every woman he could. Lilith, however, was incredibly faithful. She was also a very obedient wife. Adam was happy about having such a pure, naive and obedient wife.
One day, Lucifer decided that he wanted to have Adam's soul. He entered their home in the form of floating black dust, and he talked directly to Adam in dust form. He made a bet with him: if Lilith put her mouth around another cock aside Adam's at most one week from now, then Lucifer would immediately have Adam's soul. And if she remained faithful, Adam would become rich and powerful! Adam immediately agreed, as he trusted his wife. But Lucifer was cunning. He went to Lilith's room in demon form: a big red 7-foot-tall man, with a pair of horns on his head, pointy ears, evil orange eyes, sharp teeth, a very muscular body and hairy legs with hooves at the bottom. Lilith was terrified, but Lucifer said that he meant no harm to her. He then proceeded to lie and explain that Adam would go to Hell, unless Lilith undressed right now and accepted to suck Lucifer's cock until ejaculation. Lilith panicked. She loved Adam so much that she accepted immediately and without hesitation, wanting to save her beloved husband.
Lucifer was surprised. He didn't think it would be that easy! Of course, the bet was only about Lilith "putting her mouth around a cock". There was nothing in the bet about undressing and sucking the cock until ejaculation. But Lucifer wanted to have some fun!
Lilith undressed and her beautiful naked body gave an instantaneous boner to Lucifer. Lucifer's cock was huge. It was about a foot long and about 5 inches thick. Lilith got on her knees and put the cock in her mouth. The cock's taste was really bitter. Lilith didn't like it at all, but she had to do it for Adam. Lucifer moaned with pleasure. Just as Adam arrived and watched in utter shock, Lucifer released a enormous load of black cum, completely covering Lilith's face. Lucifer laughed and he then told all the truth to Lilith. He then walked to Adam, took him by his arms and they both turned into dust, which then flied outside the window.
Lilith was in absolute shock. She cried, realising that it was all her fault! She had to do something to save her husband!
