Much more over time?

I grew up in a large family of three brothers and three sisters. It was a normal childhood until I began to go through puberty. My hormones were raging through my young body. I remember my first sexual experience with a boyfriend of my oldest sister, whenever he stayed overnight he would end up in bed with me and my younger brother. 

During the night, when everyone were asleep, he woke me up and gestured with his finger to his lips to keep quiet. Whereupon, he lifted up the blanket showing me  his 7 inch uncut cock.It was hard and he asked me to suck him off. I hesitated and told him I had never done this before and I didn't know what to do. He turned on his side,facing me and told me to slide under the covers and get my head close to his cock. Closer up, it seemed huge and I felt excited by what was happening. I noticed right away that he was leaking liquid from the hole in the middle of his cock head. He put the covers down over my head and waited, til I got up the nerve and I took the slimy head within my young lips, stretching them wide open. I heard a muffled groan from him and he lifted the covers and said " Take more in your mouth and suck it, like you're sucking and licking a lollipop." I did what he wanted and he started to gently slide his cock in and out .

Unbeknownst to me and the guy I was sucking, my brother awoke to the sounds of me sucking his cock and was pretending to be asleep. Being my first time, I wanted to investigate the pair of huge hairy balls that dangled below on his thigh so I brought my mouth off his cock and started to use my tongue on the wrinkled sack that contained two goose sized orbs which responded to my mouth. I managed to capture one within my mouth which made him moan and groan even more. After thoroughly enjoying the feeling of having one of his balls in my mouth, I went and captured the other one until he  brought my mouth off his balls and forced my mouth over his shaft. I could feel the veins that ran along the surface of his cock as I tried to fit his entire member in my mouth.

By this time, he wanted to shoot his load so he kept feeding me his cock. And he held my head in his vice like grip until  I tasted a salty thick spurt of liquid which filled my mouth. I tried to remove my mouth but to no avail, He said, " Swallow as fast as you can."  I did as I was told til he had finished filling my mouth several times. He said after it was over "That was great", and patted my head as I let his shrunken cock slip from my lips. In the morning, I could still taste his cum and the musky masculine taste of his cock and balls. I realized from the start, I was addicted,  sucking off my first cock and I knew it was just the start.
