DANDYA-043A - I'm sorry for making your cock grow! My slender E-cup aunt took me to the women's bath and couldn't handle my erection.

I went on a hot spring trip with my mom and my slender, beautiful aunt. She dragged me into the women's bath, saying I was 'still just a kid.' It was supposed to be just us, but then other women showed up, and I was surrounded by breasts! I couldn't hold it in and got a full erection. My aunt noticed and started jerking me off secretly in the water. She couldn't handle my excitement, so she took me to a secluded spot in the outdoor bath to finish me off with her mouth and body. We couldn't stop there, and ended up in an empty lounge...
