Giving my cousin a blowjob.

I told my youngest cousin that when he turned 18 I would give him a blowjob as a present since he had never had one. His birthday came and he reminded me of my promise. Being a woman of her word I told him to come over that night since my parents were gone. When he arrived I could tell he was excited and super horny. I took him into my bedroom and sat him on my bed and told him that I needed to freshen up. I went to the bathroom and put my hair in a ponytail and put on some red lipstick. I returned to the bedroom and saw him moving his cock around in his pants. I got on my knees in front of him and slowly unzipped his pants and out came his huge uncut rock hard cock ready for some sucking. I started by licking his inner thigh up until I got to his balls. I sucked one ball right into my mouth then put both balls in my mouth, he started to melt with pleasure while. After sucking his balls I grabbed his shaft and put his tip in my mouth and slowly slide the rest down my throat. I sucked long and hard on his cock while it throbbed in my warm wet mouth. After about 10 minutes I could tell he was ready to blow his load. I told him to cum in my mouth for being a good birthday boy. I began to suck harder making popping noises as his dick went in and out of my mouth. He blew his huge load deep my mouth, once he finished I took his cock from my mouth and let all of the cum drip out of my mouth all over his cock and balls to show him just how much he had cum. He left my house on cloud nine texting all of his friends that he got his first blowjob.
