Got to spend some time with my sister in law the other day. I won't lie. I've always had a crush on her. She's pretty, curvy, and sassy. We spent most of the afternoon together, granted we were both watching our kids but it was nice to get to know her a little more. The crush just kinda grew. Nothing much happened. Although when she went to hand off my kiddo back to me. Her hand lingered a little longer. Probably just my imagination. Or was it? I dunno. It was enough to get me going. Blood rushing dlaway from my head. And as she walks away I notice she's wearing yoga pants. Fuck. Now even more blood is rushing away! Think unsexy thoughts she'll be back soon and you can't be sitting there with a bulge in your pants when she does.

She does come.back into the room. Sweater a little lower than before. FUCK. I manage to sit long enough and stare at the TV to get back to half hard. I say "I'll be back in a minute" and I jump up to go to the bathroom. Nearest one is in their bedroom. Where the best pictures of her are....I stop at one of her on vacation. Smiling big. I'm a bathing suit. I swallow hard and look back at the door, coast is clear...I snag the picture and head into the bathroom. I start into th picture. Great amount of cleavage...showing off by pushing forward a little....giant smile...she's so happy to see me....eyes behind sunglasses. But I know they're big brown eyes. Snarky and teasing. Imagine seeing them in the mirror as I'm behind her. Spanking her beautiful round ass as she groans deeply....I keep thinking of this, staring at her smile, her tits...thinking of that ass in the yoga pants....

I finish relatively quickly...clean up. Replace the picture... twist it back to the perfect spot....head back out and sit down, wallowing in a little thrill, a little guilt....watching TV. She looks over...teasingly says "have fun in there" and laughs. I laugh too....but wait. fuck does she know...? I start to sweat when I get a text from my wife "on our way back!' I announce.it to her loudly and say "well we'll have to go soon when she gets back!" Hoping I don't sound...what? Guilty? I guess ..

She goes aw man. It was nice to get to know you! We never spend time. Next time, we'll have to get in the hot tub. And...she..winked? Car horn in the driveway means it's time to slink away quickly after giving hugs and thanks for the hospitality....and we drive back home. Wife and kiddo dozing on the car. Mindd wondering back...'she didn't know...did she...? No ..but we DO have to try out that hot tub...."
