It was after Mom and Dad went to bed (wishing all of us a good night through our closed doors) that things changed in Sis' room.

After Mom and Dad had plenty of time to fall asleep, I watched as Eva gestured and said something to Charlene. It took a few seconds for me to figure out that she was suggesting the two of them go ahead and get ready for bed — and you can bet I had every intention of staying right where I was for that little event!

With my eye glued to the peephole and holding my breath, I watched as Eva was the first to move by removing her blouse; as she reached behind her back for her bra fastener, Charlene gave in and began removing her own clothes — starting with her blouse, just as Sis had. When she slipped it off, I was delighted to see that her choice in undergarments was appreciably more adventurous than Eva's: it was a frilly pale yellow thing with lace edges that barely covered her nipples. Reaching between the cups, she unhooked it and let it slide down her arms and land on the floor behind her. That left both of them standing there topless, generally facing each other and angled so that it was easy for me to compare the two sets of young mammaries. Eva's generally conical B-cup breasts were more-or-less familiar to me, sporting quarter-diameter dark pink areolas that looked like they were capped with small pebbles of pink bubblegum. Charlene's breasts were more rounded, and were actually larger than they'd seemed; at the peak of each was a pale dime-sized areola that sported a nipple that had to be half an inch long.

Looking at them, I could only dream of what I'd like to do with them.

After several seconds of back-and-forth, it was up to Sis to get things going again by slipping her thumbs under the waistband of the slacks she was wearing; a little more negotiation, and Charlene followed suit with the skirt she had on.
