I live a block down from my sister. I'm married to a wonderful man, but after 20 years the sex is a little stale. My sister's son, Terry sometimes comes over and mows the lawn when Ken, my hubby, is out of town.

Terry's 18 now, and it all started just about a year ago. Ken was gone for the week, so Sunday afternoon I opened a bottle of wine and put on one of Ken's porn videos. He doesn't know I secretly like the porn, especially with girl on girl stuff and the couger-young guy stuff. I was only in a robe, sitting on the couch fingering myself when I thought I heard the back door open. I got up and turned around. It startled me enough that I forgot the video was playing. As soon as I turned I saw Terry standing in the kitchen and my robe was halfway open. I knew it was closed enough to cover my tits, but I completely forgot about my pussy showing.

Terry is about 6'2" and a bit chunky. He has a pretty large belly that hangs over his pants, so I really didn't think of him sexually. I was a little drunk so I really didn't give a fuck if he saw my body or not. I was him look at the tv, then back to me. He put his hand down and rubbed up and down on his cock. "I don't think that's really appropriate," I said. I staggered a little as I turned around and plopped down on the couch. I was trying to focus on the tv and almost forgot he was there until I felt his hands from behind on my shoulders. His hands then rubbed over and down the front of my robe. He pulled my robe apart slightly and I felt a hand on my tit and he rubbed my nipples between his fingers.

I moved his hands away and closed my robe. He leaned down and said, "I have an eight inch cock." I laughed and said in a sarcastic way, "Sure you do. I'd like to see that." He must not have gotten the sarcasm, as the next thing I knew he was standing in front of me without his pants on. My mind was whirling from the wine, but I could focus enough to see his cock. It was only about five inches long but fairly thick. "Honey, that ain't no eight inches," I said as I looked up at him. "Not now, but once you start sucking on it, it will be." He stepped forward and his cock was about six inches from my face. He reached a hand out and put it on the back of my head. For some kinky reason I leaned forward and put my lips around his cock. It was soft as I closed my eyes and started to blow him. He got hard really quick, and I thought, "Holy fuck, it really is eight inches." I took as much of him in me as I could. I reached under and cupped his massive balls. I couldn't believe I was sucking my nephew's cock, and I liked it. I put my hand down and started to finger fuck myself.

After a couple of minutes He pulled out and told me to turn around. I turned around and knelt on the couch with my head hanging off the back. He hoisted my robe up and I felt him shove his rock hard, giant cock farther into my cunt than anybody ever had before. "Ohhhh, fuck!" I said as he started to slowly fuck me. I was fucking him back and realized I was cumming. I nearly passed out from the orgasm, but the second orgasm hit and I yelled for him to fuck me harder. He did. I felt his nuts slap my cunt lips as he fucked me harder than I'd ever been fucked. "Oh, fuck, I'm gonna cum," he said. "Give it to me," I told him as I clenched my cunt lips around his cock as hard as I could. "Oh, fuck, fuck, fuck," He said as his cum hit me so hard I came a third time. When he finally pulled out I almost collapsed.

"Turn around," he said. I thought he was gonna fuck me from the front now. I knew a 17 year old can cum several times in a day. Instead of fucking me, though, he grabbed my hair with both hands, twirling his fingers tightly and pulled my face to his cock. His cock was dripping with cum a he pushed himself back into my mouth. I didn't think I wanted to do this, but he had my hair in his hands and was mouth fucking me. I could taste his cum. I never swallowed Ken's cum, but Terry's cum was very nice. I decided I liked the taste and the texture. I started to suck him in earnest and he slowly let my hair go. He backed up a little and I leaned forward to keep his cock in my mouth. We did like this until he was sitting in the recliner and I was on my knees in front of him. He was as hard as a fucking rock as I sucked him. It only took another five minutes and he said he was gonna cum again. He wasn't holding me, and I didn't need him to. I clamped my lips around his cock and reached up under his shirt and started to roll his nipples in my fingers.

Without any more warning he started to cum. His nuts must have been full today as his second load was massive. I sucked him until he had no more cum. I swallowed more cum than I thought was possible. I sucked him dry, and when I pulled my mouth off of his cock I suddenly felt embarrassed. He got up, walked behind the couch and put his clothes back on. He turned to go out the back door. I was still on the floor. As he opened the back door he said, "Tomorrow, 10:00." He walked out before I could say anything. But true to his word, he was in my house at ten the next day, and we have been fucking ever since.
