My older sister is 38 yrs old, divorced, and lives with her 15 yr old daughter in a large house not far from mine. There is lot of work to do around that house, and a for the last 8/9 yrs, I volunteer or am asked to help out with 'yard work, maintenance, and other stuff.' During this period of time, my sister and I have grown much closer and she's a lot more comfortable talking to me about things than in the past. Last couple of years, our topics of conversation have been how lonely she is, how much she 'needs a man around to fix things, take care of her and other stuff'.
Late last summer, I was over at her house helping weather-seal her back deck. My usual 'payment' for the work I do for her is a case of beer; after a couple of hours of working and chatting, we had both developed a decent buzz. Sis asked if I would mind if she took a break; the sun was perfect in her fenced-in back yard for sunning herself. I told her no problem and kept working. When she emerged from the house, she had what I guessed was a pitcher of margaritas, but was also sporting a flowered french-cut bikini and a pair of sunglasses. 'Whoah!' I said, shocked and a little bit embarrassed. 'Ok; guess I'll take that as a compliment,' she responded. I had never seen my sister in such a revealing outfit; and the man in me couldn't help checking her out: Long, tanned legs, 34-b tits (nice!) ass a tad big, but the total package was awesome. The thought crossed my mind that if I weren't her brother and I was working on this hot divorcee's house, it would be hard to keep my mind on work...I forced myself to stop thinking like this. She was my big sister! Maybe it was the beers.
She set up her chair directly facing and laid on her back with her legs ever so slightly spread. I couldn't help feeling a little uneasy; I had the feeling that she was looking at me as she sunned herself, but she had shades on and I couldn't tell. If I looked at her, she could tell right away. 'How're things?' she asked. 'Oh, they're fine', I replied. She asked about my wife and I said fine again; though things weren't fine there and Sisi knew it. 'Been a while?' she asked. 'What do you mean?' I knew exactly what she meant. I knew only too well that I hadn't gotten any sex in around 6 months. 'Been a while for me, too...' she said. I couldn't believe where my sister seemed to be taking the conversation. But something inside me was intrigued.
Some time passed, the radio played, I worked and she sunned herself. I couldn't help but sneak a peak when I thought it was safe, but I never really knew if I was busted or not. Sis seemed to have a wry smile on her face. I was surprised to find I was getting turned on. Once, when I was sneaking a look, she reached down to adjust the crotch of her bikini and I caught a glimpse of closely-shaven dark brown pubic hair. I started asking myself if I was wrong to be so turned on by this situation; she was my big sister!! Then, as if on cue, she really shocked me: 'No peaking, now! Promise!' I glanced over to see my sister removing her bikini top. 'I usually sun myself this way.' I wanted to look but I just couldn't; I opened a fresh beer and swallowed half of in one gulp. I tried frantically to busy myself.
She was obviously up to something, and the brother in me didn't want to disappoint her, but... 'Ahhhh....that's better.' A pause. ' You know, I was only kidding. You can peek if you want.' I slowly turned to see my sister slowly caressing her beautiful breasts, pinching one big brown nipple occasionally and arching her back slightly as she did so. I was transfixed; I couldn't tear my eyes away. She had reached the horny man inside me and I was helpless. I stared at the show she was putting on for me for at least 5 minutes. Her left hand moved across her stomach toward her groin. 'You know, you've been such a good brother coming over here like you do to take care of things for me...But there are other things that need 'taking care of' too...' Her hand had slipped under the top of her bikini bottom. 'I've been wondering if you'd be willing to help me out with some of my other needs, too.' She looked at me over the top of her shades as she began to finger herself under her swimsuit. I was breathing heavily and simply couldn't speak.
My cock was painfully hard and a little piece of me was feeling shame at my arousal, but I was astonished to realize that a much larger part of me was dying to fuck my beautiful sister. It was clearly what she wanted, too. I killed the 2nd half of my beer and swallowed hard. 'I've always said I would help you out with anything you needed, Sis. I meant it.' I went inside, with her following close behind. She stopped me in the front hall and started feeling my body up and down; I could hear her practically panting. I kicked off my sneakers and took off my t-shirt; I could tell that smelled slightly of the stuff we were working with. 'Lets get in the shower,' I suggested. Before we started for the bathroom, however, Sis grabbed my face and forcefully tongue-kissed me. I have never seen a woman so intensely turned on.
