Lady Parthia found her chest being fondled under Alexander's huge hands to be both very embarrassing but also stimulating.
The way that Alexander described, no, praised her breasts and other parts of the body was something that was very novel to her because in Tibias, or anywhere for that matter, this was not a thing.
Husbands never appreciated their better halves like so.
Sure they might recite some flowery poetry or offer gifts, but they never did this kind of raw, sensual admiring in the bedroom.
Thus for someone like Lady Parthia who was already considered quite old, to have a young man lust after like so, stimulated the womanly parts of her heart.
And she could not help but enjoy herself as Alexander massaged her twin peaks, squeezing them, kneading them, twisting them, pushing them together, and then pulling them apart.
The vigorous movement soon made Lady Parthia's chest feel like the place was burning.
