Deep Cleavage

Last night we went out downtown.  The girls all dressed sexy, but I’ll tell you about my SIL in particular.  As I’ve mentioned before, she has big natural DDs and she likes to show them off, although her husband gets pretty jealous and tells her to cover them up.  Last night I walked into their house and instantly knew it would be a good night.  She was wearing a long dress.  The spaghetti straps held up two triangles of fabric that struggled to hold in her enormous tits.  The dress had a very low back as well, which made it impossible for her to wear a bra.  Not only did 1/3 of her tits make up the visible cleavage, you could see underneath her tits from the side because it was so lowcut.  No one can help but stare at braless, natural DDs in a very low cut dress.  It was glorious to watch her tits jiggle as she walked around the house.  Her husband complained, but I couldn’t wait to get out of the house with her.  

Another friend was there too, already pretty drunk.  Apparently her drunk move is to bend over and wag her ass in your face.  Not a bad move, especially when she is wearing high heels and a very short dress.  I caught a few peeks of her pussy covered by a white thong before we even left the house.  

The next few hours were spent trying to be in a good position to check out SIL’s tits.  She kept drinking, but she was still alert enough to remember to periodically push her tits back into the dress.  There is something so entrancing about waiting for a big pair of boobs to fall out of a dress.  It’s inevitable, and you don’t want to miss it.  I still haven’t seen her nipples yet, and I really want to.  

The girls finally couldn’t wait any longer, and I went with them to the dance floor.  I knew this was my best shot.  I was so turned on, holding my wife’s ass as it grinded on me while I watched her sister’s tits bounce in front of her.  SIL was ready to party, and she was bouncing her boobs around like crazy.  She didn’t wear that dress to pretend like she didn’t have big titties.  It was great to look inside her dress to see the bottom of her tits bouncing up and down.  She still had them strapped in tightly though, and I didn’t even get a peek at a nipple.

I stepped back to watch other guys grope and caress the girls.  Their friend in the short skirt backed off the dance floor.  Right in front of me, she pulled her dress up, completely exposing her ass.  She readjusted her thong between her cheeks before she pulled the dress back down.  I hadn’t expected to see that, but it was a nice diversion since I has not getting into my SIL’s dress.

The girls got tired of being groped, so they made the obvious decision to start dancing on the stage.  They all went crazy on each other up there, and the crowd enjoyed the show.  My wife started making out with one of her friends up there.  Still though, even with all the bouncing, SIL’s boobs stayed put.  I knew that since she was up on that stage, every guy in there was thinking the same thing that I was.  I hoped that one of them could tease her tits out.  

The girls got tired out, and met me at the bar.  SIL, still excited, put her arms around me and started grinding.  She grabbed me from the side, so I could feel her tits rubbing on my arm, which rested right in that magical cleavage.  She said Look Sis, I am grinding on your husband.  I tried unsuccessfully to position my elbow to push her dress off her shoulder to expose her breast.  In the meantime, I enjoyed having my arm nestled in the softness of her big tits.  The night ended soon after that, her tits still locked away behind those straining cotton triangles.  I made progress, because now I have felt her boobs, but I will have to wait for another night to actually see them.
