Take it from experience, next time get your arms under her back seamed stocking legs to make sure they stay upright and hold her wrists down with your hands. Once you have her pinned like that then begin the blast. You'll find out you'll get bigger loads and a longer time it stays hard in order to keep a nice seal so the cum doesn't escape. She should be pregnant in no time at all.
