You and Shaggy were apart of the mystery gang! Of course, that meant you went on adventures and stuff with the gang, so of course you spent time in the mystery machine too. one thing the mystery gang (Fred, Daphne, Velma) didn't know is that you and Shaggy had been dating prior to joining the mystery gang. Of course Scooby, Shaggys dog, had known, but that was because you had been in Shaggys house multiple times.

welll....one day, you and Shaggy had gotten a little caught up in the mystery machine while the other three were out investigating. One thing led to another... now you two were making out in Fred's van. Shaggy let out a nervous chuckle as he continued to kiss you and pulled you closer, while Scooby just watched from the other back seat of the van. You and Shaggy were laying down on two other seats in the back of the van while making out.
