In the beginning, the relationship with my sister-in-law was rocky to say the least. But after she finally got rid of the girl-beatin-up-little-beotch she was married to, we started getting closer by the minute. I'm not sure when I actually began looking at her in a sexual way, but I am sure that she had me ogling and having impure thoughts in no time at all. At first, she seemed oblivious to my sudden attraction, but after we spent more and more time together, it sure looked like she was going out of her way to get my attention.
Don't get me wrong; I am in love with my wife, and of course I felt guilty at first about my sudden interest in her sister, but I couldn't seem to stop myself. Besides, my wife Terri had been hinting for quite a while that Tammy and I should do the nasty. With comments like "she hasn't been laid in a while, maybe you should help her out;" "time for you to perform your husbandly duties for Tammy;" and my personal favorite was once (or twice) during sex she said "I wish Tammy was here." Needless to say, it didn't take long for me to let go of my guilt and be totally honest with myself: I wanted to fuck my sister-in-law.
The weirdest part is that they are total opposites. While Terri seems prudish outside of the bedroom, Tammy is a wild child no matter where she is. Terri is slim and Tammy is. . .well, let's call it full figured. She's not fat, she's just got a little extra cushion. But it looks good on her, and, let me tell you, that girl's got an ass that'll kill you. WOW! But, perhaps the main difference (and most likely the main reason for my attraction) is the level of self esteem, or lack thereof, in Tammy's case. You see, wife beaters have to break their wives down emotionally first. That way they'll put up with the beatings. If he has her convinced that she's unattractive to everyone else and that she's lucky to have him, she won't leave his sorry ass when he decides to prove his "manhood" by beating up a girl. Yeah, that's real manly, alright.
So even though she finally wised up and sent him packing, the emotional scars he left behind were far from healed. Pity wasn't the reason behind my newfound lust; I guess it was the challenge. The quest to turn this unsure hottie back into the confident woman she deserved to be was quite a motivator; not to mention that she's gorgeous and, ooh that ass!
Anyway, her house was falling down around her, and, being the only man in her life, I started helping her fix the place up. I put a metal roof on it, put silicone around the windows and winterized everything on the outside. Then we started working on the inside. She had hired a crew to remodel one of her bathrooms, but they couldn't legally do any plumbing. Rather than call a plumber and get raped on labor charges, she called and asked me to help her. Actually, she set it up with Terri. Let the teasing begin!
She started out slow, of course. When I arrived the next afternoon, toolbox in hand, I noticed that the shorts she was wearing were skin tight. Upon closer inspection, I saw that there were no panty lines, not even the thong arrow. Although it was odd for her to be wearing shorts in the wintertime (commando no less), I didn't think anything of it. I simply enjoyed the view as she led me to the closet behind the bathroom. The wall in the closet had been left stud-bare so I could get to the plumbing.
"Thank you for helping me."she said as we reached the closet.
"Hey, it's no problem." I replied, stepping past her and into the closet. "I'd rather do it this way than have some plumber charge the shit out of you."
"Well I'll help you, of course." she said. "You'll just have to tell me where you need me."
"Mm. . .a lot of possibilities in that statement." I joked. Our recent flirtations had given her confidence a badly needed boost, therefore I took every opportunity that presented itself.
"Be careful," she replied, "don't bite off more than you can chew."
Touche. Mentally patting myself on the back for the progress of her self-esteem, I turned to the plumbing and began to remove the old drain kit from the bathtub. I had to lay on my back to get to it and, as I suspected (or feared) the damn thing was so corroded that it wouldn't budge. Not to mention that I had zero room to maneuver and, no matter how I tried to prop the flashlight, I couldn't see shit.
"Can you hold the light for me?" I asked.
"How am I supposed to do that?" she asked.
"Well, just turn it on and shine it right here so I can see what I'm doing." My smart-ass came out before I realized just how precarious the situation had become. Realizing my ignorance, she decided to have fun with it.
"Ok, but you may not want to tell Terri about this." she teased.
"What are you talking about?"
That's when I looked down and realized that with my legs sticking out the door, and the need for us to be in the same space; she would have to straddle me. For her to hold the light where I needed it, we would be in the cowgirl position; fully clothed, but erotic nonetheless.
"Oh! Sorry. I'll see if I can make do." I said.
"Yeah, I knew you'd chicken out." she replied. Of course I couldn't let that pass.
"Who's chicken? Get down here if you're woman enough." There. I turned it right back around on her.
Our eyes met and held for what seemed like forever. I couldn't read her expression and wondered if I'd made a mistake. Was she mad? Did I fail some test? Was she going to tell Terri that I'd gone too far? Reaching above my head, I resumed my work, (without the light) and tried to put the whole sticky situation behind us. Apparently, I had nothing to worry about. While straining to break the connection, I could suddenly see what I was doing because the light appeared right where I needed it.
I could feel her thighs pressing gently on either side of me, her crotch poised just millimeters from my own. She had leaned forward to hold the light in the right spot, but why didn't I notice her breasts before? The collar of her shirt gapped, giving me a perfect shot of her braless tits and hard nipples in all their glory. I quickly looked up to her eyes so she wouldn't catch me ogling, but it was too late. She didn't say anything, but I could tell she'd seen me. Luckily, she was smiling.
"Boy I hope you don't tell her about this!" I said.
"That we're in this position, or that you're enjoying it?" she asked, with that insanely cute, mischievous grin of hers.
"Both."
"Don't worry," she said, "I'm just as guilty as you are."
"Promise?"
"Promise."
"Good." I said.
I returned to the task at hand. As I strained to break the connection on the fitting, I must have raised my hips a little. I heard her sharp intake of breath as my crotch touched hers. My dick had been at full attention since we started this little episode and I could tell that it had wedged perfectly along the length of her pussy. I lowered my hips, put the wrench down, and looked at her.
"I'm sorry, I didn't mean. . ."
"It's ok," she interrupted, her face flushed, "we'll keep that a secret too."
"That it happened. . . or that you enjoyed it?"
"Both." she laughed.
"Good."
As we shared a chuckle, I lost what little resolve I had left. Given the fact that she was having just as much fun as I was, I couldn't resist pushing a little farther. I reached down, grabbed her hips and pulled her down to me. She gasped as our loins came into full contact with each other for a second time. It occurred to me that, short of super-human strength (not to mention breaking both of her legs), there was no way I could have pulled her down on me without her help. She could have easily resisted, but didn't.
"Sorry," I said, letting go of her hips, "I couldn't help it." I was right. Although I "let her up," our position remained unchanged.
"You can't stop now, teaser." she said; her face still flushed. She put the flashlight down and pushed herself up; her hands now supporting her upper body. "I warned you about biting off more than you can chew."
