Getting a 'feel' for the situation

You lean into her again kiss her briefly before continuing down to her neck. Your hand reaches out and gently cup one of her breasts. She gasps; you stop and look at her, half expecting her to push you away. When you look at her she has her eye tightly shut and is blushing.

“Winry, look at me!” you say sternly.

“What is the matter Winry? Don’t you like this” you say while gently kneading her large breast through her overalls. “…No! it feels…so naughty” she struggles with her words as your hand stimulates her. “But you beautiful body seems to like it” you add. You rub your palm on her breast and find her nipple hard due to all the attention it’s receiving. You pinch the sensitive flesh through the fabric.

She yelps and shudders as a wave of pleasure goes through her body. “See what I mean,” you say continuing to press and gently twist her erect nipple. “No…I… please” she says.

As you passion increases your hand slides down slowly to her backside. Your hands skim over the soft curve of her rear. You can feel the heat coming of her body. You squeeze her ass almost involuntarily. This causes her to moan into your mouth. You are encouraged and continue to rub and squeeze her ass.
Suddenly she breaks the kiss, breathing heavily she looks at you, “I think…think that we should stop…before” she says haltingly.

You look at her eyes; she seems to be embarrassed by what is going on, more so about the pleasure she is feeling. You yourself feel torn, you want her really badly and you are certain that if you push her a bit then she will yield. On the other hand you may try to persuade her…
