"The gap" was something that models bragged about awhile ago. It was derided as an unhealthy body standard. But holy cow, besides everything else, Jana had it in spades!
I had a co-worker who had very small breasts but otherwise shared Jana's super-fit physique- the butt cheeks that held their two distinct shapes against the tightest of pants and were so high and firm they looked like they would float away if not attached to her. Plus the muscular quad arches and the thigh gap. My job with her was the second of a double shift, so I usually would pass out when I got home. But if I interacted with her at all and did not masturbate when I went home, I would awaken to an erection of an almost unfamiliar size and hardness.
Now seriously imagine being with someone who had that AND Jana's boobs.
