I have a super cute and kind childhood friend who I've known for a long time, but she doesn't wear a bra and her nipples are so erect that you can see them through her clothes, and when she bends down, her nipples are exposed through the gaps in her clothes and she comes to play with me in a defenseless position. Naturally full erection! But my childhood friend found out about my erection! But my childhood friend also seemed to be excited and started clinging to my dick, so he was super sensitive with a clearly defined pink erection.
