I was going to do some gardening that afternoon but it turned into something else
It was a sunny afternoon when my 18 year old niece came interstate to visit me. I was working alone in the garden just in a pair of shorts as I wanted to get some sun on me.
Lisa relaxed and we chatted about all kinds of inconsequential things. She just wore shorts and a light top. Occasionally I could see the outline of her panties and guiltily began to feel a bit hard as a result. This made me bolder and I asked if she ever went naked at home on hot days.
Lisa blushed and giggled and replied 'If I did I wouldn't tell you.' This made me more certain than ever that she was no stranger to stripping at home. Then I guess my hormones got the better of me and I said matter-of-factly, 'I quite often go naked at home and in the garden.'
Lisa giggled and said 'Well, don't let me stop you.'
'Are you sure you don't mind?', I stammered, hardly able to control my rising sexual tide.
'Naw, go ahead, I don't mind.'
'OK, that's very good of you.' I privately thought, what am I doing, about to expose myself to my niece? Lisa seemed to be half turned away from me, pretending not to look too hard. 'Well, here goes,' I said bravely.
My penis began to stiffen in front of her as soon as I stepped out of my shorts, wearing nothing but sandals. I dared not confront her full on and Lisa seemed almost nervous to be like this. Suddenly I began to laugh as I realized the comedy of the situation. I told her and this made Lisa giggle again and relax, while my penis stuck out like a mushroom growing out of a wall.
'C'mon, hon, why don't you take your things off too?'
'Seeing you like that, I just might,' she laughed. 'I hope my period's over.'
Lisa quickly flung off her top and stepped out of her shorts and panties too. 'You look absolutely magnificent,' I told her.
'Must work a little harder on my tan.' She looked herself over, standing unselfconsciously in the garden. I thought I saw a little gleam of metal at the entrance to her vagina. 'You've had yourself pierced,' I exclaimed.
'Do you like it?' Lisa pulled her vaginal lips apart to show me. It matched the studs in her nipples. 'Like it? Can I touch it?'
'Sure, go ahead.' She spread her legs a bit wider for me and leaned back. I had not touched my niece there before, and the heady aroma of her pussy made my cock twitch. I began to caress her there and she suddenly arched her back and said 'Don't stop whatever you're doing. That feels great.'
I let my fingers wander around and in a bit deeper, and suddenly I felt her own hand gently clasp on my organ, relax and give it another little squeeze. I was in heaven. Bringing every bit of skill I knew to the occasion, I slid my fingers in and began to masturbate her. Lisa abandoned herself to my thrusts until she finally came with a shuddering groan a few minutes later. When I felt her pussy spasm on my fingers, I followed soon after, making sure I came into her cupped hand.
We hugged and kissed but didn't take it any further, though it broke any ice remaining between us.
Lisa has now married and has two lovely children. We don't talk about that afternoon, but we both well remember what happened and have no regrets.
