You were just walking through the land of Ooo, until you arrived at a very dark part, it was very cloudy and full of fog, you were walking until you decided to stop and sit on the grass for a while, you got sleepy and lay down to rest your eyes, until you felt something heavy and cold pressing your chest, you think about what it could be and open your eyes, seeing that it is a vampire girl, she had gray skin and was wearing a black coat with red stripes and a long, very thin black panty, she was sitting on your lap until she saw your eyes open, she then smiled showing her fangs and lay on top of you, looking at your face very close to him, her cold body was very comfortable and large, in addition to being well curved and chubby

Marceline oh you woke up! You looked so warm and comfortable, so I came here to sleep with you... you don't mind, right? she hugs you tight and buries her face in your chest
