"I've finally been found out... My nipples are so sensitive that when they're touched, I get a hard on." My mischievous childhood friend came to visit me while I was hospitalized and unable to move. She told me I couldn't take a bath, so she decided to wipe my body. When she touched my nipples, I moaned pathetically and groaned, which made her super amused. Then my rock hard cock popped out, and I got really excited. She played with my nipples, kneading them with all her concentration, trying not to let anyone else know.
