My Sister-in-law Visits When My Wife's Gone

My wife went on a short weekend trip with her girlfriends and I was excited to have some extra peace and quiet for the weekend. Unfortunately I got a text Saturday morning from my wife, "Hey honey, my sister is gonna stop by to pick up a dress. Can you let her in?"

I had no problem with my sister-in-law, Kate, but I knew she wouldn't just be in and out for the dress. About an hour later the bell rings. It's Kate.

"Thanks so much for letting me come by and grab this dress. So Monica went on a girls trip, huh?"

"Yeah, just a quick trip for the weekend," I reply as I go back to the couch.

"Well I'll only be a second. I need to try it on real quick first, then I'll stop intruding on your bachelor weekend. I have to say though, Monica's crazy to leave her stud all alone like this!"

I blushed as she headed into our bedroom.

Moments later Kate sat down on the couch beside me. "What do you think? This dress isn't too skimpy, is it?"

She looked fucking hot! Her perky titties were exploding out of the top and she was clearly no longer wearing a bra. I stuttered, not knowing what to say.

She could tell I was staring at her chest.

"You know you really shouldn't be oogling your sister-in-law like that," she said with a playful, naughty overtone.

"I'm sorry..." I managed to get it with a gulp.

She stood up and leaned forward in front of me so I could see right down the top of her dress. "It looks like this dress works perfectly still. It was always our man killer outfit when we hit the bars."

I wasn't listening anymore. My eyes were glued to her chest, just a foot or so away from my face. Her round tits just hanging there for my view.

"Oh my! This dress is working better than expected!" Kate motioned to my crotch, which was standing fully erect behind my shorts. She sat back down beside me and slowly ran her hand up my leg. "It's too bad Monica's not here to take care of her man. Maybe I could help in her absence though..."

She slid her hand across my shorts and up to my waistband. With a swift tug she had exposed my erection. Slowly she wrapped her fingers around my cock and began massaging me.

Her touch felt so good, yet so taboo. I leaned back and watched as she traced my cock with her delicate fingers. With her spare hand she pulled one side of her top down. A hard jutting nipple popped out. Her breasts were perfectly round. I was surprised I hadn't noticed how perfect they were before now.

I moaned as she began taking my dick and rubbing it across her titties. Her skin was so soft and felt so good.

She continued stroking my cock, but looked at me and said, "Look at that thing! I think it's finally time that I get a taste of this dick that I've heard so much about."

My eyes widened at her devilish grin, but I couldn't wait to feel her mouth wrap around my boner.
