I love flexing! It's a great workout haha also i LOVE doing this while I'm inside someone so they can feel it! Yummmm! I was going to make this a paid post but I just think bodies are fascinating and I wanted you all to see it hehe
The first one shows the change in texture when I flex, the second shows the change in colour (more red), and the third shows how the ridge of the helmet grows. haha :P
