Dog on the Tuckerbox

The act of inserting ones testicles into a females anus and then ejaculating over her arse cheeks.

Sam was attempting the Dog in a bathtub (balls in ass and dick in vag) and got his balls in but couldn’t get the angle right for the vag so had to sterile for a Dog on the Tuckerbox shooting his load on Nicky’s ass cheeks. (Tuckerbox)
