The sexual art of rendering beef fat in order to inject it into your penis hole to achieve a large, fat penis once the fat congeals. Then during oral sex, when you ejaculate, instead of giving your partner standard semen, you give your partner a complimentary KC strip in their mouth.
I never liked giving blow jobs but his cock was so big I had to do it. I was rockin’ that cock when I realized he was grubtunneling me. “True meat in my mouth!”
