Little Sister's Amazing Underboob

amn, Sis, how big are those things anyway?”

“You were just feeling me up; you should know how big they are.”

“I mean, what size bra do you wear?”

“32DD” I groaned again. How had I never noticed that my skinny little sister was some sort of slim and stacked titty goddess? I was so hard and horny after getting my first chance to touch someone’s breasts. At this point, I didn’t care that they were my sister’s because they were absolutely amazing!

“I said don’t go making this weird. Let’s get back to hiking.” I tried to get back into the mindset I had when we got on this trail; that we were going to have to work hard to do the 4 miles in a reasonable amount of time. However, I simply couldn’t stop thinking about Tanya’s tits. I wanted to touch them again, I wanted to stare at them, and I was quickly becoming obsessed with what my sister would look like topless! It probably wasn’t surprising, then, that I kept stopping and looking behind me to see how Tanya was faring on the trail. It really hadn’t gotten steep yet, so neither of us was having to work that hard.
