My parents had gone on vacation leaving my sister and three brothers home. We're all adults, I'm the youngest 19 going to city college as are Kurt 21 and Brad 22, my other brother Jeff 26 works but is just a goof and my sister Karen 29 is a bad relationship expert. I was going to go to the beach with a girlfriend but after I walked over to her house her brother wouldn't loan her his car so we scrapped our plans and I went back home.
Walking in the back door I didn't see anyone even though Kurt, Jeff and Karen were home when I left. I looked into the living room and saw Jeff and Karen wrestling on the floor. Jeff's 6-3 and 180 pounds to Karen's 5-6 and 195, she's got a slender upper body but wide hips, a big ass and thick thighs. To my surprise Jeff was on his back and Karen was sitting on his stomach facing his feet. I was about to walk in and congratulate my sister when I saw her reach into Jeff's shorts and start jerking him off.
So mesmerized by what I was seeing I stayed around he corner and just watched. Jeff leaned forward and squeezed Karen's ass as she peeled his shorts back freeing a stiff 8 inch cock. She then stood up, pulled off Jeff's shorts, took off her clothes and climbed back on top of him in a 69 position. This from my two siblings who never had a good word to say about the other.
Karen's head was bobbing up and down with most of Jeff's 8 inches between her lips, hugging his legs and he was lapping away at her muff, squeezing and playing with her fat soft ass. I was so stunned at the strange happenings before me I failed to hear Kurt come up behind me. He put his hands on my shoulders and whispered in my ear, "Man they're really going at it." I just nodded. Kurt then put his hands around my waist and hugged me close to him. It felt a little weird but mostly what I felt was a rock hard boner knocking against my fat butt. Kurt then moved one hand up to my breasts, the other past the waistband of my shorts to my pussy and rubbed his boner against my big butt whispering on my ear, "Makes you really hot doesn't it? If you want to get it on we can go upstairs so we don't disturb them."
Horny as hell I turned around quickly and grabbing my brother's hand started for the stairs. We were to his room and naked in a flash, I plopped down on the bed and just stared at the 11 inch cock waving in front of him. It was the biggest dick I've ever seen in person. I'm 5-2 tall and weigh 180 pounds with a 38C chest and big fat soft butt, Kurt is 5-9 and weighs 220 pounds and ooh baby, that dick.
Kurt stood on front of me and I reached out grabbing the shaft of his huge dick with both hands aiming it at my mouth. I got the head of that monster in my mouth easily enough but had to take my time getting much of it in very far. Getting the hang of it I had more than half of Kurt's cock sliding between my lips pretty easily and oh it felt soooo good. Kurt was very sweet reaching forward and gently rubbing my arms and shoulders.
I really like to get suction when I give head and I had to catch my breath so I let Kurt's cock slide from my mouth. My brother had his hands on my shoulders and leaned down to kiss me on the forehead and gently eased me onto my back then got between my legs to go down on me. I was already pretty turned on, a nice hard cock does that to me, and Kurt went right to my pussy, nibbling my lips, kissing my thighs and finding my clit to get me off for the first time quickly.
By the fourth, maybe I don't know, time I came I was sweating and breathing hard so I squeezed my thighs around Kurt's head to give him some kind of signal. He looked up at me and I said, "Fuck me now." That must have been the signal he was looking for because he got a condom from the nightstand and was quickly kneeling between my legs. My brother gently put his cock in my pussy and slowly pumped inch after glorious inch deeper into my hot box.
I was still sweating but with the slow paced fuck I was so enjoying I was at least able to catch my breath so I asked Kurt to fuck me harder. He picked up his pace causing my belly to shake like a wave pool as he pushed my fat butt deeper into the mattress with each stroke. Kurt put his hands on my shoulders and plowed into me with all his weight, it was heaven.
The effort had Kurt sweating too, when I wrapped my legs around his body and squeezed he sighed and shot his wad then fell forward on top of me and we hugged and kissed.
