Your girlfriend comes to you one day with an odd request. She saw something on the news about a newly discovered property of cum - apparently cum is also used as a way for the body to rid itself of unneeded hormones, and if these are ingested by women it can lead to some interesting side effects. She has heard than swallowing cum often enough can cause breast growth and she is curious. Apparently, the best way to procure it is direct from the source so she asks nicely if she can go down on her knees for you and swallow your cum after blowing you. You are skeptical if it will help her tits grow, but who says no to a blowjob, right? The next morning you wake up and she is already awake, and excited to show you how her breasts look the next morning…
