As Marilyn drives you, the two of you discuss tactics to capture as many girls as possible. Marilyn does most of the talking, with you doing a few honks and engine revs to make your points. Not perfect, but you are understood, and Marilyn has some good ideas.

To test them, you slip into a parking lot and wait for a woman to wander past you. This takes longer than you would like, but eventually A nice little Asian lass in a revealing outfit goes by your side door. You quickly open the door and jerk into reverse, closing the door again as it hits the girl. She is thrown onto your back seat, and now you close the back of the seat on top of her, leaving only a few scarps exposed. These, you quickly suck in until she is completely covered.
Digesting her proves harder than expected, but hardly unpleasantly so. You are tasting every inch of her delightful skin and "climax" 6 times before she is liquid. She enjoys the whole thing nearly as much, coming 4 times.

As the back of the seat returns to upright, Marilyn remarks "Very good, now for a big strike." and starts driving you. She seems to have a destination in mind.

This proves to be a bus stop, with 3 lasses waiting. Marilyn drives you to the stop and asks "Off to a party?" Getting the expected affirmative response, she offers to drive them to it if the party can use another girl. The two blonds quickly agree. The redhead is more cautious. "We were told to watch out for strangers..."
"Oh Stephanie, you worry too much. If she tries anything, you have me and Sally to help you. How is she going to be able to handle all 3 of us?"
She still hesitates, but buckles. "Allright Michelle, but I'll take the front seat."

With that the ladies pile into you, buckling up like good little meals. They were doomed from the moment the doors closed, but the belts will make it easier.
After Marilyn has driven to a relatively quiet spot, she signals you, and all of the passenger seats close like giant mouths, folding the lasses up so that only heads and calves are visible. Marilyn gets busy with her paperwork, enrolling each lass as laboratory equipment and administering their potions. Once that is done, she tells you to finish eating them. They of course protest, but a couple of nibbles and their heads are inside the seats and no more can be heard.
Despite having 3 to deal with, you make quicker work of them than you did the one earlier. Which is a shame in a way. There is just so much more contact, enjoyable contact, this way. There are definite disadvantages to being a car, but as long as you can enjoy getting your fuel this much, you are not going to complain.

But all good things come to an end. After you have finished with the last bit of the last lass, Marilyn asks "You are pretty full now, but I bet we can capture a few pieces for you to have later. It will be a bit of a load to carry home, but we should be able to do it. Ready to try it?"
