Dexter and Sheldon are two Boob Science geeks who couldn't get laid in a whorehouse. Using their skills at computer magic, they create Mandy (Daphne Rosen), a living, breathing, super-chesty wonder woman. She will do anything it takes to get Dexter and Sheldon the dream girls they want to fuck.
In this chapter, Mandy scolds the guys for their poor tit-handling skills and attempts to educate them using Maggie Green.
"Women with big boobs have needs," Mandy tells them. "Obviously, their tits need attention. They need to be rubbed and teased. They need to have their pussies licked, teased and fucked! Sit back and let me show you horny, little devils how it's done. They need to...cum. A lot! And luckily for you, I can show you exactly how to do that." Mandy proceeds to do just that.
