after you finish having sex and took off your condom filled with the creamy essence of life, make a balloon from it and throw it to the unlicensed hostile kindergarten located under you window. just think of the face of the person that will pick it up in the morning. smile with delight

sperm balloon is to mean when you are having sex, you rip off the condom and put the condom on your partners mouth. she will then blow and make the condom into a balloon. she then ties the balloon and sits on it till it pops and the liquid goes everywhere.
oh my god, last ngiht was great, she made a sperm ballon and it went everywhere. but it was so fucking awesome.
