Marcus finds booze and something more

Marcus goes to the back to the store where the **** it's located

"Oh man! Someone already grabbed all the good stuff!" he says disappointedly, still he grabs a couple of bottles and opens one of them to have a quick drink, he is too distracted to notice someone is approaching him.

"Sorry I beat you to it stud, but I can give you something even better~" An erotic female voice is heard, Marcus turns around and sees a voluptuous sexy succubus. She is completely naked, her red skin seems to be wet making it shine and look even sexier, she has a bottle of tequila on her hand.

Marcus turns around and drops one of the bottles when he sees the sexy demoness approaching him while he has no way to escape. He can't help but stare at her large breasts bouncing hypnotically with each step she takes. Involuntarily his cock hardens inside his ragged pants.

"I don't mind sharing some of mine if you give me something in return~" says the succubus, she then pours some of the content of the bottle on her tits as she approaches Marcus. "Go on, drink~ You look thirsty."

Marcus moves his head towards her breasts. He is completely enraptured by the demoness, without saying a word or making any attempt to resist her he starts licking the **** dripping from her teats, he then starts to suck her nipple and a jet of black milk fills his mouth, her milk combined with the tequila it's the most delicious thing he has ever tasted, despite the burning sensation he feels traveling down his stomach he can't stop sucking her milk and the succubus pours more tequila on her breast so he can drink more.

The Lilith Strain is already starting to affect Marcus, he can't ignore his hardening cock any longer and pulls down his pants releasing his erect member that's already leaking precum. The succubus notices this and giggles.

"Now it's my turn~" She pushes Marcus away from her breasts much to his exasperation, she hands him the bottle of tequila and gets on her knees. She starts to suck his cock while using her long serpentine tongue to jerk him at the same time.

"Oh fuck! This...this feels amazing!" Marcus takes a quick drink from the bottle of tequila that fills him with more confidence and bravado. He then grabs one of the succubus horns and starts fucking her face.

"Yeah! **** on my fucking cock you slut!" Marcus holds her horn even harder and moves his hips more violently. He can fill his muscles strengthening and growing larger along with his cock. Using his other hand, he easily pulls and rips his remaining clothes showing off his new stronger, manlier, body that it's slowly starting to turn red.

The Succubus can only groan as she feels his cock getting larger and thicker inside her mouth, she starts to suck him even harder until Marcus can't resist anymore, he lets out a savage growl and cums inside her mouth feeding her his soul and filling her mouth with black cum.

Marcus transformation finishes, a pair of horns surge from the top of his head along with a pair of demonic wings and a cock tipped tail. He takes a moment to admire his new, perfect body and enjoys how big and sensitive his transformed cock has become.

The succubus licks clean the dregs of cum that escaped her mouth and stands up. The soul she damned wasn't particularly special or virtuous but she still feels invigorated by it and the incubus she created isn't in any way inferior to the one who infected her, she was about to push him down and ride his cock when a voice caught her and Marcus' attention.
