I was eighteen old

When I was 18 old I was still studying and working to make some money , the owner of my company impressed me , his age was almost great and he had healthy and strong and , and with the time this man was able to practice sex with me ,I had a fuck from behind anal sex because I was virgin , an unintentional mistake occurred during sex as he entered his penis into my pussy I felt great pain but at same time I felt a nice pleasure and I told him continue don’t stop , I felt and had something warm inside my pussy , for the first time in my life I throw out semen and felt as strong as an earthquake shaking my body , I said to myself, Is this the sex ,
