At the end of an 11 hour ballbusting session, Akira's slave is at his limit. She tells him that he has to endure one final busting; Akira shows no mercy! Showing off her new heel boots, she starts to play with his mind and make him nervous. After using the boots for some good hard scare-kicks, Akria has her slave remove her boots so she can make sure she feels the satisfactory impact on her skin. Imagining how much it must be hurting her weak little slave as she feels her own foot getting red already. Ensuring that the last hits are the HARDEST, Akira snap kicks her foot so hard into his testicles that they ends up juicy red, swollen and almost ready to pop out of his body! Scared he will be castrated before the final bust is over, Akira's slave trembles as he spreads his legs wide before silently falling to the ground after each kick- unable to hardly even take a breath.
