My cousin came to my house just a while ago. She's a nice girl in her teens. Now I'm not thinking anything wrong here but stay with me. My youngest brother lifts and has good muscle definition. He's in the kitchen cooking something and I'm here on the computer in the living room. I'm not as shredded as he is cause I don't workout. She walks in because she has to use our printer for her school assignment. She starts talking to me and I'm trying to get the printer up and going. While I'm doing this she looks into the kitchen and sees my brother. I realize that she freezes. She looks away and now I'm seeing that her body language is off. She acting like a scared rabbit now. I tell her to WhatsApp the document to me and I'll print it from my phone. She pulls out her phone and her hands are shaking and she's taking shallow breaths, can't stand properly now and fidgeting. I print the document for her and she thanks me. Before she leaves she steals one last look at him. Now in that whole interaction she doesn't even call him and make him know she's there. All she saw was HIS BACK.

This isn't about fucking your cousin but how women react to a muscular build alone.
