this reminds me of my band's song "dustin (the period song)", that goes like this:

female menstration
a sore vagina's vacation
from the cursed cock
but dustin wont hear that talk....YEAHHHHHHH

dustin fucks girls on their period yeah
he does it all the time
he thinks they're big and juicy ripe
and awfully prime....
for the pickin
a slick little hole
to stick his dick in!

dustin thinks pms is sexy
yeah it makes him hot
dustin always knows
when all the sexy females got
menstruation
he does it all for
the lubrication!

chorus: dustin thinks that its a go
when you're visited by aunt flo

at first i thought it was kinda weird
but dustin doesnt care
ill admit he did convince me
when he ripped off my underwear
and spread em,
i was horny and so
i let him!

dustin was happy
to expose me to something new
in fact it wasnt half bad we decided to continue
the fiasco,
he likes his taco
with a lot of tabasco!

chorus
