Cousin fucked in front of my Girlsfriend

My cousin and I have been fucking with each other for a long time
and so far my girlfriend doesn't know about it either.
But today I told her and it seems to be cool too
do. She comes to our hotel and we start a threesome.
First the two blow my cock and then I lick
both out of their wet shaved pussies. Then it goes on really cool
they stretch their holes towards me and let me fuck them one after the other.
Alternately I fuck her pussies through and inject at the end
I my girlfriend's cunt full. That makes my cousin so horny
that she also licks my sperm out of her pussy.
So the ice is broken now it can go on.
