Mom and Dad had passed away this past year in a car accident an had always wanted to do the complete trail so we decided in their honor to make it our... goal for them.My name is Joy an I’m the oldest at 22, 5’6?, 130#,36-30-36, my next sister is Judy 21, 5’4?,110#,34-26-32, and my little sister Gracie 17, 5’8?, 120#, 34-24-30. Our first day had been just great we had hiked the trail with several other people but they had left the trail to sleep in one of the nearby towns for the night an to skip. I had no idea that a mans' nipples could feel like this. It confused me even more than the forced tongue-cleaning I was giving.I tried to touch my cock for some relief but got another hard slap. "I told you Slut! Don't touch it! If you do what we say and prove yourself worthy we will take you home with us tonight. We have lots of dirty work for you and if you do a good job we will allow you to cum as payment. Now get some suction going, I want to hear the sounds! Suck out whatever is left in. She wagged her butt slightly around the still-rigid spar of her nephew's cock. "When do we do it again?" Right away." Martin put his palms on the pale ass cheeks and pushed away. Inch by inch his giant prick came out of his aunt's ass, dripping with his come."Ahhhhhh," Jacqui said in satisfaction. "That feels good. It's been so long since I've had a cock in my ass."With a little grunt of exertion, Martin pulled the rest of his prick out of her butt. It dangled between his hairy, muscular. I was torn - jealous of Ned, the pompous little prick fucking my girlfriend's mouth - yet turned on by the sordid kinkiness of it all. I decided to just remain silent, see what happened, and besides, at least she wasn't fucking him. Alice and I were at our sexual peak, and the next few weeks we couldn't get enough of each other. We would suck and fuck at lunch, right after work, late at night, and sometimes wake up at 3 or 4 AM to do it some more. Mowing her expansive lawn, she would.
