You don’t see a lot of people enjoying that Slingshot ride (mainly because something that shoots you 200 feet skyward should be seen as torture device), but the girl below made sure to get her money’s worth as it seems she had the best orgasm of her life while riding it. Or she faked it so she wouldn’t make the Slingshot feel bad.
That counts as foreplay.
