Unexpected encounter with a supernatural force leads to an intense and unusual masturbation experience

Our protagonist, a typical guy with an average sex life, finds himself at home, alone and feeling a bit horny. He's got a girlfriend, but their intimacy has been lacking lately. As he starts to pleasure himself, an unexpected supernatural force intercedes, aiming to give him a sexual experience like no other. The room spins, the air grows heavy with anticipation, and suddenly, his girlfriend materializes, her body glowing with an otherworldly aura. She drops to her knees, her eyes hungry as she eagerly sucks his throbbing member, her skills far surpassing anything he's ever experienced. Her tongue explores every inch, driving him wild with pleasure. But she's not done yet. She turns around, revealing her exposed ass, which she proceeds to lick and rim, her greedy tongue working wonders on his arousal. The encounter ends as abruptly as it began, leaving him spent and satisfied, his memories of the encounter a tantalizing mystery.
