Buff girlfriend's transformation

You get back from a long overseas trip and your girlfriend Claudia excitedly greets you at the airport. You notice she’s wearing a giant baggy sweater, despite the heat, which seems odd but you’re too pleased to see her to pay much attention. Once you get home she strips off and shows you what she was hiding: in your absence she’s been hitting the gym and it has been paying off in a big way. She’s gone from being skinny and petite, to seriously jacked. She flexes her muscles, telling you all the muscle-building supplements she has been taking have sent her sex drive through the roof. She strips for you, noticing how much you are enjoying her new physique and explaining how much she’s looking forward to riding your cock now you’re home, and taking control in bed.
