Grundlebate 

A highly stimulating sex act whereby your sexual partner tightly, but gingerly, pinches your grundle while you furiously and feverishly masturbate yourself. To perform properly, your mate must pinch the grundle between their thumb and forefinger and must tug this fleshy area back and forth and up and down in rhythmic and synchronous harmony to the recipient's stroking and beating of their turgid cock. Said act is known for explosive orgasms but can result in a very sore taint if performed too frequently.

Carl exploded in a body quivering orgasm after his girlfriend helped him get off with a little Grundlebate action. She tugged a little to hard though and Carl's taint was a little tender to the touch the next morning.

Grundlecakes 

(n.) grundlecakes are created when excess vaginal secretions seep from the vagina and run down to the grundle where they dry forming a flaky, crusty, build up. This usually occurs during aggressive foreplay or hardcore sex in the missionary position when the female becomes increasingly aroused and wet. The term grundlecakes refers to both the caking of the vaginal secretions to the grundle area, in addition to the actual flakes and clumps that shed from the grundle upon the bedsheets. Grundlecakes is not merely a female phenomena but can form on the male if the vaginal secretions are spread during intercourse to his grundle and dry there.

Erin was slightly disgusted and surprised to find grundlecakes all over her bedsheets the next morning after Anthony provided her with a weeks worth of orgasms the previous night.
