The good news: Sonja is reforming right on her doorstep.
The bad news: Sonja is reforming right on her doorstep, buck naked.
The really bad news: Larry is looking right at her.
The really really bad news: Sonja trips as she tries to dive behind the bushes and lands, fully exposed, right on top of them instead. And she seems to have twisted her ankle in the process.
At least Larry is a gentleman and helps her to her feet. But that allows him all to many chances to grab what he shouldn't without her having grounds for complaint, and confirms her ankle is really hurting. A desperate desire for getting out of sight battles with a desire for clothing, and is won with "Get the door open!"

"Nobody is answering the door."

"Use my key!" She'd punch him for being too stupid, but that would uncover what little she is able to hide. "It should be in my pants."

Thankfully, his fumbling for the pants, and then for the key lets her sweater fall, and Sonja can grab it, at the cost of a little pain and embarrassment, and by the time Larry has the door open, she can cover the vital parts of her...almost cover anyway.
Her dive inside is hampered by her ankle, and by Larry's attempt to save her from falling. The resulting tumble ends with her on top, on the floor, in a rather suggestive position.
Quickly scrambling to her feet, and regretting it as soon as she put weight on that ankle, Sonja explains "My folks won't be home for some time.

"What about Jason?"

"What? ...oh... Ah, he shouldn't be home for some time either." She hardly finishes saying that before she realizes there can be implications to such a situation. Even if she had been in his reach for two days now and he had not tried anything, not much anyway..., this situation is still different, dangerously so.
"Would you like a snack before you head home?" Hopefully that will distract him from wanting more...

It does and Sonja drapes herself on the couch and extends her legs. "Now, be careful with that ankle..." It only is as Larry is being careful with that ankle that Sonja realizes she is still nude below the waist, and Larry can see far more than is proper. But there is nothing to cover up with, and as much as that ankle is hurting, she doesn't want to risk moving it. This would be horrible if she was a normal lass, but she is home now and Anne should change her back to Jason soon. She will just suffer.
Which proves hard to do. Larry's lips sliding over her skin are quite sensuous and her excitement is building, leading to waves of rapture when he finally reaches her damp need. As Larry consumes her hips, she pulls off her sweater, almost casually exposing what she had been so desperate to hid not long ago. But she is feeling too good to really care. Indeed, as her tender mounds were kissed, she is feeling some regret that this will be the last time. She of course wants to get back to normal, but she has to admit there have been some very good moments..., One of which happens just as her head starts inside, and makes enough noise to make Sonja very glad her mother is not home.

"Thanks for bringing my comics to my home. Just lock the door and put the key under the mat." As Larry does as told, Sonja settles back to be digested for the last time, she hopes.
