Chapter 4: Matt Fucks Tammy

Incest Sex Story: Chapter 4: Matt Fucks Tammy - If there's one thing I learned growing up it was if you're fifteen, horny, and "available" you tend to have a lot of boyfriends. Years later it appears my cousin Tammy has learned the same "lesson". Even better, her current boyfriend didn't mind having me join in as well, even though I was six years older than him.

Tammy flew to the door, motioning me to stay where I was. A moment later she opened the door and in walked Matt. My first impression was “WOW!”. No wonder my cousins both adored him. What was really hot for me was that even though they both CLAIMED he was sixteen, he certainly didn’t look it. Had I passed him on the street I would have guessed him to be more like thirteen or fourteen. Tammy wasn’t exactly the tallest girl by any means but he was maybe even a little bit shorter considering she was barefoot and he had his shoes on.

Matt’s eyes were locked on Tammy and he never bothered to even look around so he didn’t see me on the couch in the living room. The kid didn’t waste any time, that’s for sure. He put his arms around her and quickly slipped it under her T-shirt, grabbing her tiny little ass and pulling her closer to him. They kissed in the entranceway as he squeezed her ass with both hands, one grabbing each butt cheek.

“I couldn’t wait to get here!” he exclaimed, “Wow, you look really hot in just a T-shirt.”

Tammy was beaming of course. Then she looked over in my direction and Matt followed her eyes. I knew when he saw me as his eyes widened and his mouth hung open just a bit. The funny part was that he didn’t loosen his grip on her ass one bit. I doubt much of anything would have torn his hands away from fondling her.

“Oh Matt, this is Kelly. She’s a cousin of mine, like Kristen.”

Matt didn’t say anything, whether it was him waiting for Tammy to finish her explanation or he just didn’t know what to say, who knows? I would have put money on the latter, though...

“Earth to Matt!” Tammy giggled, “I told her what we did with Kristen and she wanted to do the same. Is that OK with you?”

I took that as my cue to stand up and show him what I looked like. “Hi Matt!” I greeted him, “I’ve heard so much about you - ALL of you for that matter.”

Matt suddenly seemed to be a little shy. Was it that I was so much older (and taller) than him or maybe he wondered exactly what it was that I had heard about him. I tried to reassure him by saying, “Oh don’t worry, Kristen gave you quite a glowing recommendation!”

Matt was still staring at me. Not only was I seven years older than Tammy and two years older than Kristen, but both of them looked younger than most girls their age so I must have seemed relatively ancient to him. It wasn’t just age either, if where he was staring was any indication - my chest. Whereas Tammy was barely an A cup and Kristen was a solid B, my C size boobs must have looked pretty good to him. I also knew that as cute as Tammy’s ass was, it was tiny and not nearly as round and hot as mine. I almost felt a bit guilty as he kept staring at me and all but ignored Tammy - almost. Tammy must have noticed where his interest had shifted as she took a little action of her own to regain his attention. Her hand moved down to his crotch and she started to rub him through his jeans.

“So Matt, are you ready to fuck me?” she said casually, as if it was just a natural thing for a girl like her to ask him.

Well, THAT got his attention and he grinned back at her.

“That’s better, now let’s go down to my bedroom,” she appeared to offer, although I don’t think she was really open to any alternatives.

The two of them headed down the stairs to her bedroom and I followed right behind. Her bedroom was small and even though she and Kate had a set of bunk beds, it didn’t leave a lot of room for three people. Oh well, I was sure we would work something out.
