Hi everyone. I've just finished wanking off into a satin black half slip which is now in the wash.For a bit of fun, I was wondering which piece of underwear to wank into next. A pair white of lacy knickers, a sexy black thong, a lacy black slip with a single slit on the side or the white slip that you can see in my pictures & vids. Please let me know which ones you'd like me to spunk into and these will be the I cum in. I will make a vid of the winning piece of sexy underwear getting my white creamy spunk. Thanks for all who take part.... if any of course, but it would be nice if some of you guys would. Cheers MM
