Aria Nicole arrives at the chemistry lab to work on her project during off hours to make sure she has full access. She finds a chemical compound readily available on the table and gets to work. However, as she's studying the compound and it's reaction, she has an accidental spill. She panics as even the professor isn't around and this lab has no showers! Aria tries to talk herself down because after a moment, nothing is happening. But then, her chest begins to feel tingly. She starts to panic as her chest swells - and soon realizes the properties of this compound result in expansion! Well she's not soooo upset as she gradually swells from a double A to a double D and far beyond. Aria Nicole, confused as to whether or not she should be panicked or horny, continues to be distracted by her continuously growing breasts, which looks really HOT as her shirt stretches to its limit. She rubs them, smiling, and giggling as they grow to large Z cups. Her body is so hot and tingling and she can't help but rub herself so much that she even cums in her own pants to her oversized tits. With boobs this big, the possibilities are endless!
