Your girlfriend Claudia is sipping from her water bottle after a workout. You ask for some since yours is empty and she pauses. 'I just added a new supplement to it', she confesses. She explains it’s something experimental – no proper name, just a string of numbers and letters – that one of the other women at the gym gave her. You are annoyed – it seems irresponsible to take something without knowing what is in it! She just rolls her eyes and explains she wants to get bigger. She wants huge biceps, and a thick back. Besides, adds Claudia, don’t you want that too? You love her muscles after all. She pauses and gets a sparkle in her eye. There’s meant to be a way to kind of turbo-charge this growth supplement. Apparently, swallowing cum kicks it into a kind of high gear and the best option is to get it straight from the source. She grins, as she gets down onto her knees in front of you.
