When man and girl get together to and proceed to start having intercourse. The man will then take out his penis and shove it up her nose and go in and out until his baby yoghurt flies up into her nostril.

In any situation, if this does not work, then man should start to get a blow job, and before he drops a load, stick it into her nose and let if fly loose.

Some noses may be tough to fit it in. But if you just stretch it, you should be alright.

Friend:
