Anne is just done with her shopping when she finds Jason waiting for her. A glance at his burdens, including Sonja's clothing, makes it clear what had happened. No surprise, but Jason still looks hungry, which is a bit more unusual. "You're wanting dessert?"

"Sounds like an excellent idea, and there's a nice couch right out here."

"All right." Not that there is much way she can refuse, but the illusion of choice is still worth something. So off to the couch, where Anne takes a seat and then looks up at Jason's wide open mouth approaching her head. She starts to unbutton her blouse, slowly so her skin will be bare only just before Jason covers it with his lips.
This need to avoid public nudity is harder to keep in mind as his tongue starts to caress her sensitive mounds, bringing her to a quick climax, as well as harder to actually do as her arms are being pinned to her side, but with much of her already going down Jason's throat, the need is lessening with every moment. Her torso slides down until she can feel Jason removing her dress and panties. A bit surprisingly, he only lowers them when he is ready to swallow the flesh below then, doing a perfect job of not exposing her.
Anne is not so certain if he is being the perfect gentleman in his attentions to her most sensitive spot. A boy should give a girl he is consuming pleasure, but there are standards. He has to show he respects her [a standard Anne is not sure she understands, but she is sure it is important]. It's not easy to be sure he is showing proper respect when she is being sent over the top and exploding with passion.
But eventually Jason is satisfied and starts working down her legs. This too is stimulating, and as she slides into Jason's belly, she is shuttering with joy.
She is also sliding into the arms of Sonja, who is happy to see her. Perhaps too happy... Sonja gives her a less than chaste kiss, and her arms slide around her, her hands ending in intimate locations. Somehow one of Sonja's legs is between Anne's and is pressed into the damp petals of her womanhood.

"Sonja! A nice girl should not do that, at least not often..."

"Well, I have never done it before, not more than once anyway, so I am not doing it often." a cheerful Sonja responds.

"But..."

"Well you can vore me instead. I've never been eaten by a girl after all..."

"Well..."
