[Unfortunately for Monika, Soundwave is utterly clueless on anything regarding romance. It doesn't even hit him that this position he's in may seem romantic. At least he isn't pressing his body against her, since she might see it as "cuddling" ... Or rather, he'd prefer to prevent her from touching his crotch plate. That part of him is still sensitive after everything that happened on the bed.

That aside, the shampoo glides over her back, getting as much of the soap on her above the surface of the water, then her arm, lifting it up gently just as he did with her left arm. He's attentive, too, getting the sponge under her armpit and between her fingers.]

Cleaning someone up? No, I wouldn't say so.

[The only difference is that he isn't cleaning up energon/blood, which he wouldn't say out loud.

There's a pause as Soundwave considers bringing the sponge on her front now. It's a high likelihood he'll touch her breasts... No, the forbidden touch can wait. Punishment can wait. Instead, he'll set the soapy sponge on the edge of the bed and reaches for a shampoo. It says it's for haircare on it, so he figures for humans they have different product for the body and hair. He squirts some on top of her head and very, very, very carefully press his metal hand on her and slowly apply it all on her hair, before going down, fingers running through her strand, careful to not have them be caught between his finger's joints.

It's so silky and smooth.]

I have- [He stops himself.] had friends who were as small as you, proportionally.

[Which may explained how he's so incredibly gentle.]

It is a first with a human, however.... let alone a humanoid body.
