If I thought things had been awkward a bit lately, nothing had prepared me for what was coming next. The heat was on!
I came home a Saturday afternoon. My mom and sister were outside in the garden - where they always were nowadays if they were at home. My sister was laying on the sun bed, my mom sitting next to her. She was just about to rub sunscreen on my sister's back. I watched her squirt some of the substance in her lower back and with long form strokes rubbed it in. Mom paused for a moment, pulled on the little strings behind my sister's back and untied my sister's bra. Then, she continued rubbing my sister's back. She leaned forward, said something to her daughter which I couldn't hear, and continued her almost massage-like motions.
Then, the most insane thing happened: mom's hands moved to my sister's sides, caressed the swells of her breasts, then pushed her hands underneath them and....cupped them! My sister rose up, moms hands got a better hold, and squeezed her daughter's tits again. She smirked at her, then said something else. Sis took her bikini top off completely, and mom did the same. Mom said something else to her daughter, got up, and walked away shaking her hips. Then she looked right at me, as if she had known I was standing there. "Hi son!" she cheered, definitely loud enough for my sister to hear as well. But my sis didn't bother to cover up.
After that Saturday afternoon, she took the teasing to a whole new level. When she was making sure I was watching - which basically was all the time - she'd always found a way to show skin. Wearing a button-up shirt? She'd bite her lip, and undo a few buttons. Wearing a shirt with a zipper? She'd toy with it in front of me, pulling it low enough to flaunt the swell of her tits. Wearing a shirt with shoulder straps? She'd make sure one of them was off-shoulder.
Then there were the skirts. Oh god, the skirts. My sister was parading around in tiny little fabrics that hookers on the corner of a street would even find revealing. Some were skin tight which had a tendency to ride up. Others were pleated which danced around as she walked. And if she wore those, she always had a bounce in her step.
She knew she had my attention, and she knew she was making me hard. And she was enjoying every second of it. As mom wasn't like that at all, I wondered if this was my sister's kink: an exhibitionist. That she likes to show off her body. And that me watching her, fueled her desires. And that only caused her to tease me more - like catch 22 situation, spinning rapidly out of control. It was like...something or someone held her back before, and that had blocker suddenly been removed.
At this point in time, I was still considering trying to find a fix for this situation. Yes, she got me hard almost 24 by 7, but I still felt guilty for what was happening. But finding a solution, was hard as hell when there's a vixen seducing you constantly. And finding creative ways to do so as well.
Well, I mentioned how she would use her cleavage to tease me. That was happening today as well. She was wearing a black top with a zipper. As she had done so many times before, she used the zipper to tease me. This time however, she "zipped" a little too far, and - even though briefly - got a full view of her nipples.
And she just said "oooops", then smiled at me, and pulled the zipper up just a bit.
A couple of days later, she did the same, flashing her breasts. Mmm, they seemed so enticing, a nice hand full, with her perky nipples always standing proud... After the fourth time, she didn't even "apologize" anymore, just teased me with them.
Sunbathing poolside? She didn't even bother putting on a top. God, watching her oil her tits with sunscreen was so delicious. Or - just as hot - she'd take a t-shirt, soaked it in water, put it in the freezer for a bit, then after a while put it on while it was still wet just ice cold - and that really made her nipples poke.
I found myself less and less in the basement.
"Hey bro, can you come in here for a sec?" I heard from the bathroom as I walked by in the evening. I stopped in my tracks. Was she now inviting me into the bathroom? The door was ajar, and I pushed it open. I found her sitting in the bathtub, taking a bubble bath. And there were lots of bubbles. Hesitantly I moved closer. "OK, I'm here..." I replied.
"We've been living together for how long and I still feel like I don't really know what's been going on in your head lately."
"And you want to talk about it now? While you're taking a bath?" I asked surprised.
"Well, why not? I'm only taking a bath, nothing weird. People take baths all the time."
"Yeah, but....you're naked...." I stammered, not being used to her dressed in nothing and being so close to her.
"Oh please, there's so many bubbles, nothing to see right now..." She was so casual about it.
"OK, so....what would you like to talk about?"
"You ever feel like we talk about everything and nothing at the same time?" she asked with a genuine curiosity.
"You mean we never have a meaningful conversation?"
"Yeah, you know....what's going on in your life right now? Besides talking to your sister who's bathing naked in a bubble bath right beside you." She giggled a bit saying it like that, almost mockingly. "Like, what's going on in that basement of yours?"
I took a deep breath, realizing I needed to tread carefully here. Nothing about the accidental mix-up!
"Well, I was working on an idea to make a fat-burning cream, one which allows you to target certain areas of the body."
"Oh, that would be a fantastic product! Are you close to realizing it?"
"Well, I was making some good progress, but with the heat down there it's hard to concentrate."
"Ah, bummer. Sorry for not wishing you colder weather, because I'm loving this weather" she cheered. "So, if your mixture is ready, would you use it yourself?"
"I tested some of the batches on me, yes."
"You don't have a whole lot of fat. Where did you rub it?"
"My belly of course. With mom's cooking, that's the first place it grows..." I joked.
