Not a chance Shrunk in an Amusement Park chapter 13 by Louka31

She really wants you all to herself and is not sharing you with anyone. She apologizes and prefers to go home alone but can still see her tomorrow.

All you can here is a muffled version of this conversation but finally, she starts walking again. You hear a car door and she gets in. Once she closes the door, the car starts, she slides away her bikini bottoms again 

"How about little bit more fun before the drive home" she says before beginning to masturbate with you inside, pushing you deeper inside while she does eventually you hit her cervix. And just when you think you can't go any deeper, it begins to swallow you feet first.
