Your friend Claudia has been your gym buddy for several months now and you are so curious about how her muscle growth is progressing. She’s been wearing baggy sweaters to lots of your gym dates and it is driving you nuts – you have a real thing for muscular women. One day she invites you over to hang out and reveals she has actually been going to the gym a lot on her own, because she wanted to surprise you with her muscle growth. She noticed you staring one day and realised how much it turned her on to have you checking out her muscles and physique. She flexes for you and gives you a JOI, encouraging you to admire how big and hard her muscles are now.
