willyfluff 

A small collection of fibres produced only by Davo whilst wearing a school uniform and drinking effes.
Harvesting of the willyfluff is celebrated in western samoa between the 3rd day of every month and the next full moon. Specified forceps must be used when collecting the fibres. It has a high market value in Japan as an aphrodisiac but may only be taken in small doses. not heeding this warning will result in ocular googliness

That willyfluff gave me a massive boner last night

When a young man orgasms nothing comes out.

I was young when I fucked her so all I could manage was a Willypuff
