Visiting My Aunt At Home

When I was about 18 my aunt who was then in her late 40s got me to do some gardening jobs for her, paying me a bit of pocket money each time. One afternoon I hadn't planned to visit her, but discovered I had left one of Dad's tools at her place and Dad would need it the next day. Although my aunt only lived a few streets away, it was a hot afternoon and I thought it would be nice to get a drink at her place when I got there. I knocked on her door but there was no reply, so I went round the back to her garden. I could see her lying on her back on a sun lounge with her back to me, her face completely covered by a wide brimmed straw hat. I didn't want to shout, so opened the gate. She didn't stir and I guessed she was sound asleep. She was wearing a blue floral cotton sun dress, and as I got closer I saw she had pulled it up to her thighs to get more sun on her legs. Suddenly I had the urge to see how much of her I could before waking her. I tiptoed around till I was looking straight up her thighs. Her garden was surrounded by a high wooden fence so privacy was good. This was just as well since I discovered she had not put any panties on and I found myself staring at her vulval lips and getting an unstoppable erection. Auntie was snoring lightly now, and I figured that as long as I kept quiet she wouldn't hear me, so I quietly pulled my shorts and underpants down and boldly faced her at the same time stroking my naked penis. It didn't take long for me to explode and in fact I squirted so violently that some of my cum landed on her leg. Luckily she was so soundly asleep that this didn't wake her, but I wondered whether I should try to clean it up or not. I quickly pulled my pants up again, and then bent over and gently wiped the bulk of it off with one finger. Then I had a really strong desire to touch her down there, so I bent over and gently wiped the slippery cum from my finger to her clitoris, which was just peeping through. My heart was racing and I was scared she might wake up any second. She smelt very womanly down there and it was starting to excite me again. I suddenly drew back when she began to stir and realised I wouldn't be able to escape without her hearing me, so I shrank behind her where she couldn't see me even if she opened her eyes. However, I couldn't believe my eyes when she moved her legs apart, reached down there with one hand and rubbed her clitoris herself a little as if it was itchy. She put her finger into her mouth and I wondered if she could taste my cum on it. But no, after moistening her finger with saliva she slowly began to masturbate herself there. She kept this up for 5 to 10 minutes, not knowing I was watching, concentrating on her clit and becoming more and more excited until in the end she brought her knees up and jerked in pleasure. Half of me was frightened she might see me, the other half was wild with excitement at witnessing this show. Finally I slowly backed up to the side gate and waited until her orgasm had settled. I knew the gate would creak when I opened it, so I decided to open it and call her at the same time so she would think I had just come in. "Auntie Kate!" She whirled around, quickly pulling her dress down and I could see her face red with embarrassment. I was standing in the open gateway pretending nothing had happened. "Omigod. Did you see...?" I still remember her unfinished sentence. "I knocked on the front door but you didn't answer, so I came round to the side." "Next time please knock on the gate a few times in case I'm asleep." "Yes auntie." I tried hard to conceal the damp stain on the front of my pants that told the true story of what had happened!
