Looser fuck!!!!! Impregnation attempt goes completely wrong!!!

I am soo willing to get pregnant and have been waiting so long for this sex....I calculated my fertile days and was so horny....today it would finally happen....I let my cunt get pregnant...I ordered the sperm buck to me and told him exactly how to do it...I finally want a thick belly!!!! At the beginning everything went well.... his cock was mega hard and horny...first he fucked me from the front and then I wanted to ride him..... in retrospect probably not a good idea:( I moved up and down nicely on his cock and what does the stupid looser ???? At the decisive moment he pulls out his cock and squirts in the air.....what a shit...how am I ever supposed to get pregnant with such stupidity???? Do any of you know a potent cock from the Cologne area who knows how to do it right ????
