"Then a good drink now, and get plenty of that saved for the futureeeee... whoa." For an instant he's stunned once more, holding a sense of wonder in his eyes at the view of just how full her breast were. Seeing the way milk were immediately at the point of edging free from those nipples, it hadn't taken a second thought.
By now the distance between them had decreased to the minimal, contently leaving him overshadowed by Morwen's generous bust. "Here, let's get a bit of that pressure off." Sora's certainty on the matter held a true branch of shameless as he'd bring those hands to her breast, allowing the warmth of his grip to seize them as that greedy mouth immediately latches to one her nipples.
Just a tinge of that sweetness immediately got him prompted. It leads to him hollowing his cheeks, allowing for that suction to increase as he'd happily allow that stream of fresh milk to satiate his hunger. On the other hand, to help alleviate that pressure considering how much she has saved, her other breast would be given a perverse knead as it's gripped and carefully squeezed.
