So, thankfully Mat was not the first person to get Abby into this situation, otherwise they would be at this forever not really going further. Because Abby talks a big game, but she's terrified of all manner of intimacy. Even if the situation meant she'd likely keep her pants over her thighs at least.

A small measure of mercy, that.

Still, kissing and being explored are hardly bad things, so she lets that continue for a bit. Not wanting to break the spell by being too needy, instead she guides his hand that had teased her breast to a more specific purchase on her waist, while she carefully hikes her undershirt up so it quickly is lead to skin. Which hopefully says more than she needs words for as to where it should be.
