Your girlfriend comes over, saying she has to tell you something serious. You think she wants to break up, but she spills the beans. She says she has breasts that... inflate, when her body ingests cum in any way. That's why you always have to wear condoms, why she never lets you cum in her mouth. Yeah, right. You don't believe her and tell her as much. She gets pissy and says that she'll be back tomorrow, and you'll see then.

She struts in, and you can't believe it! Her boobs really are bigger! She goes into detail, telling you how she sucked off the young guy down the block. His cock was so huge, she could barely handle it in her mouth, but she swallowed every drop of his cum. She tells you how she felt her breasts tingling, stretching and growing with every step she took home. You're so hard for her, and she calls you out on it. "You want me now, don't you? Well, too bad. You didn't believe me, so now you have to wait another day." She walks out.

You are eagerly awaiting her the next day when she stumbles in, off balance with GIANT tits and still half cum Silly. She found a frat party, she tells you. 6 different guys, with all the pledges watching and taking turns sucking her tits. She doesn't leave anything to the imagination, and you can't handle it anymore. You have to have her. "Am I big enough for you yet? Come on then, let's go to bed."

After your tryst she lays in front of you, covered in cum, bigger than ever before. Her stomach has inflated as well, now you both know her limit. She dreamily tells you how much fun she's had, and how you should do it again, after her swelling goes down.
