During lockdown I've found a liking for this solo act:-
I put on some satin knickers, tan tights, skirt & underskirt. Then I put a carton of unopened Custard down the back of my knickers which gave me a square bulge. Then sit down heavily on a hard chair. When the carton splits the custard squirts all over your privates and gives a great sensation. Stand up and sit down a few times and the feeling is immense - Try it!
