My sister went on a business trip, so I ended up taking care of my niece for a while. The J-system niece I hadn't seen in a long time had breasts that were obviously huge and bouncy. The developing, swelling chest was too dazzling for me, a single middle-aged man...! Unable to resist the swaying breasts as she leaned forward, I impulsively did it right away! I sucked on the delicious, fair breasts over and over, made her climax with adult-level thrusts, and then came inside her tight pussy! I injected a lot of sperm into her undeveloped uterus!
