You're in the shower while Asma talks to you through the shower curtain. She shows off her new leggings and exclaims how they make her ass look bigger - if only there was something to increase the size of her A cup breasts! She begins brainstorming and decides that extra protein in her diet might work... but where to find protein? She remembers that cum is filled with lots of protein, so begins to try to join you in the shower for some fun! You deny her the opportunity, so Asma sneakily takes things into her own hands. Asma spies your week old pyjama pants on the bathroom floor and knows that you've always got a bit of cum at the front of those, so while you're showering she opens them up, finds your cum stained pants and begins licking the creamy mixture from them. She moans in pleasure at the taste, before waving you goodbye and hopping into the shower herself. To her surprise, while Asma is showering her breasts begin to grow! Ever so slowly, bigger, and bigger, and bigger! She cries out in pain initially at the sudden growth begins to pull at her skin, before exclaiming how big and wonderful they are! She doesn't know if she can handle the growth, however she knows she wants to push through to see how big these breasts can get! She starts giggling her boobs, before suddenly realising that her breasts are changing again, but this time they're shrinking! No! No! No! Asma calls out in sadness as she watches her big tits shrink and shrivel up to their original size. After seeing how good her breasts can look, she doesn't want those A cups any more. She wants something bigger and better! She knows what she has to do - look for more cum. With you having left, she has to get creative. Asma raids the bathroom trash looking for the remains of an early morning wank. Sure enough, in a wrapped up tissue she finds the cum that you thought you'd thrown away. Its all hers now! She pours the contents of the tissue into her mouth, allowing it to dribble down her chin and onto her chest. She uses her fingers to wipe up every last drop of your spunk into her mouth. Sure enough, Asmas breasts begin to grow once more! Beneath the towel she has wrapped around her, her chest begins to expand and her breasts visibly grow once more - even bigger than what they were the first time! Asma yells out in joy as your protein works its magic on her body. Once you come home, Asma reveals to you that she's used your disposed cum to increase her breasts. But this isnt the end, Asma likes her new breasts so much that she needs a constant supply of cum. Any time. Anywhere. And from who? You. Asma
