My aunt had a beautiful boxer named Max. I always did like to fell Max's balls and cock but that was all I ever did. One day I was visiting them and they had to go shopping , so I stayed til they came back. They said they would be a couple of hours. After they left I  started to fell Max's balls and cock. I never had a chance to be alone with him so I started to stroke his cock. Turns out Max was a stud. His cock started to get hard and big. This made me real horny and hard. I took of my jeans and started to stroke myself and Max. Max turned and started to lick my hard cock and balls . I liked this and layed back and let him lick me. I was layind back on the sofa and Max jumped up so his front paws were on the sofa straddeling me. His now large hard and juicy cock was touching mine. I slid down futher under Max and took his cock in my mouth and his balls in my hand. He started to hump my mouth and I got really hot. I wanted that big cock in my ass. I went into my Aunts room to find some kind of cream to use. Max followed me with his hard cock ready to go. I checked a couple of drawers and found her underwear drawer and couldn't help myself . I put on a pair of her nylons and a garter belt. I found hand cream on her night stand and squirted a load in mr hand and started to stroke Max again, His cock got real slippery and I got on all fours and Max first started to lick my ass but then got up on me. I reached back and guided Max's cock into my hole. It was so big I never had anything that big up my ass , but after a few seconds it felt great. His big member sliding in and out of my hole. Soon Max began to whine and moan and he shot his load of cum in my ass. I could feel the warm cream inside me. I  got up and my cock was ready to explode. I went to my Aunts drawer and got out a pair of her panties and put them on and rubbed my bulge against Max's ass and shot my load in her panties . I cleaned up and waited for my Aunt and Uncle to get back. I had sex several more times with max but never like that time.
