It was so amazing feeling my 16yr old baby boy cum deep inside my belly!! I was on top and had all 12 inches of him inside of me! When he told me he was gonna cum, mommy reached around and grabbed his balls! Mommy continued to grind my babys big cock into my belly!! I started playing with his big balls just as he was ready to cum! He started to fertilize mommys hot belly while mommy was still grinding on him! I drained all his young hot fertle sperm into my belly! I felt it shoot behind my belly button!! I have a hot fire in my belly now! Its all his young hot fertle 16yr old sperm! I love him!
