On one condition.

"Oh sweet heart, you sound so pretty when you beg like that." Brian rolls his hips under you, squeezing a little more inside. He feels big. "Tell you what, if you beg in just the right ways for me, I'll treat you gently for your first time."

You turn to look back at him, nodding.

"I'll say whatever you want... just... please..."

"Turn around and face me then, and get those tits out."

You comply, your body feeling a surge of cold lonlieness as you pull away from the cock, but as soon as you've twisted around in Brian's lap he begins lining himself up again and a hot shudder runs through you. He grins at your reaction, and keeps doing so as you unbutton your blouse, revealing the straining bra within.

"Oh don't stop now sugar. Let's see what your Daddy paid for."

Flush with arousal and embaressment you shed your blouse and undo your bra, letting your enhanced breasts loose for Brian's admiration (and anyone else who should be looking this way.)

"Oh that's beautiful," Brian trails a hand over them, stroking the smooth flesh and teasing your nipples and making you squirm. "Now, doesn't that feel more like we're lovers? And lovers don't just have sex for fun do they? You want me to be gentle? Then I want to hear you beg for me to knock you up. Oh, and while you're at it, be sure to call me 'Sir.'"
