MY FIRST TIME TO USE A CONDOM

I entered a shop and bought a pack with 3
condoms, looked at them curiously for a while wondering how on earth I could use them. The lady at the counter noticed my puzzlement and asked sincerely, ''Have you ever used a condom? Do you know how to put it on?'' l blushed said,"No!" The
lady took one condom and opened it and wore it on her thumb as an example.'' This is how you wear it. You have to make sure it's tight!'' I was even more puzzled by this. I was just an
innnocent young man. She noticed how shy and confused I was."You must be a virgin," she said teasingly. "Have you ever had sex?" l said, "No!" Then she looked around the
shop; there was no one but just the 2 of us. She
called me behind the counter, opened the door leading to the back-
rooms and invited me in. She quickly locked the
door, told me to hurry up coz "..we don't have
time!" She pulled her short skirt up, her panty
down, opened her legs, and lay her back on a
table. Then she told me to wear the condom on just like she had told me. I did, and she pulled me close, and oh yes there I was right deep inside her wet sweet flesh. But Oh My God no, in just 10 seconds inside it was just too much and I came tsaaa tsaaa tsaaa ziii. The lady feels it too, she feels the hot cremora inside her, and asks me, ''Did you put the condom on like I told you?" "Yes, I did. Just like you told me!" I replied. She says, ''Let's see!" I showed her. "Oh shit!" she screamed. "You are supposed to wear it on your penis not on your THUMB, you dummy!'' Now d baby she had for me is now 8 years and I don't know
wat to do because she said I didn't ask for my child since these years. Is it my fault?
