We'd been living out in the country for a while when our new next-door neighbors moved in. It was a mother and two daughters- one about 18, and the other about 20, all redheaded, and all gorgeous. You'd met them a few times before I did- helped them move some things in, and then come home and been VERY attentive to me afterwards, so I knew that they were at least interesting. Finally I had the time to go and take them a welcome basket, so I started out one morning after I'd gotten you off to work.
I knocked at the front door, and when there was no answer went around to the back yard. They had a similar back yard to ours- lots of trees for privacy, and shady nooks all over the place to curl up and read a book in. As I rounded the corner of the house I saw movement, and just as I began to say hello I noticed that it was the two girls in the hammock. They were lying beside each other, oblivious to my presence. The older girl was holding the younger girl's face in her hand and kissing her, while the younger girl had her hands in her sister's shorts and was obviously very busily stroking her. I couldn't help it- I just stood there and watched- half shocked, half horrified, and very, very turned on. I watched as the older one lifted her sister's shirt and bent her head to her sister's small breasts, fastening her mouth on to a nipple and sucking. I could almost feel the tiny little nipple under my own tongue, and putting my basket down, I leaned back against the tree and watched from within its overhanging branches as I slipped my hand into my shorts.
The younger girl finally managed to get her sister's shorts off, and as I gently rubbed my clit I could see her plump young pussy appear- even from 10 feet away I could see the glistening of her juices. I watched as she inserted a finger into her sister's ass while rubbing her clit with her thumb, and watched the other girl's hips raise as the hammock swayed. However long they'd been doing this, they'd certainly figured out what each other liked- the older girl was moaning and gasping as the younger one silently fucked her with her small hand.
I couldn't help myself- I slid my shorts down to my hips, and wet two fingers with my now gushing wetness, and then slid them into my ass as I continued fingering my clit. Of course I came almost immediately, and then again and again as I watched the two sweet girls in front of me. After I couldn't take it anymore, I leaned up against the tree, and was standing there trying to catch my breath when I felt a soft hand touch my cheek from behind me. I turned around in shock, to see a woman who could only be the mother of the two girls in the hammock, who she was watching with an indulgent look.
