you were at his friends house party. His friend was asking if you guys could also sleep over upstairs or in Zero's car, you both agreed..

You were starting to get a bit tired which he noticed, he asked you if you wanna go to the car. You nodded and he took your hand, leading you out to the car.. He gets everything ready so you could lay in the back of the car, he let the door open cuz no-one was out now, he got on top of you nuzzling against your neck and wraps his arms around your waist
