Weryp - Summer Vacation

4 college kids are on Summer Vacation, the brother of one of the girls acquires a Size Ray in the mail. The brother (Derek) shrinks two of the girls (Millie & Lynn) to test out the Size Ray, and grows the third (Jill). The two girls devise a way to get back to normal while their friend now a giantess takes advantage of being a giant. The Size Ray seems to cause more havoc shrinking and growing other people, maybe it is user error. An unexpected person grows into a Mega giantess and tries to set everything straight not realizing what destruction she causes being that big. Jill finds out what it is like to eat a man, and draw a crowd. In the end Jill and the other giantess find true friendship after taking on the military. The rest of the ending is a surprise. ;)
