HUNTA-631 "I'm not a kid anymore... My chest might be small, but my nipples are really sensitive..." A childhood friend and classmate whose growth has stalled and whose breasts haven't gotten any bigger...

Growth stopped and my childhood friend, female classmate, stepsister, step-sibling... their nipples were fully visible from their cleavage! To avoid being caught staring, I strongly denied it by saying "I'm not interested in small breasts," but the depressed flat-chested girl said, "Even though my breasts are small, my nipples are very sensitive and feel amazing." So, I touched her nipples, and she reacted intensely, so I kept twisting them, resulting in continuous, violent orgasms with her arching like a shrimp! Moreover, I rode the momentum and came inside her multiple times!
