First, a secret revealed

"Uhmm... Are you going to sign that?" The delivery girl suddenly asked, and brought Emma's eyes back up to her's again with a dazed look. "Or are you done staring at my tits...?"

Obviously the girl was fairly used to this kind of reaction as she just stood there and smiled, but was also curious as she mostly just got it from guys being fresh out of bed. Having another woman look at her the same way was rather new to her, and even more flattering somehow.

"I-I'm sorry...!" Emma managed while scribbling her name onto the parcel and handing it back to the brunette at her door. Her face was pleasant too, she thought to herself, though her eyes were still drawn back to her generous bosom. Her cock twitched and stood at full attention, forming an obvious bulge at the front of even her fluffy dressing gown.

"No worries!" The girl assured her with a wink and a smile, and was just about to turn and leave when she looked down and noticed what was odd with the whole picture. "Whoah...?!"

"Err..." Emma glanced down to see it as well, and found herself stumbling backwards while her face blushed crimson red and her arms flailed up to her sides as if unsure of how to cover herself. It all just resulted in her gown falling open however, revealing her generous cleavage and also the impressively sized cock that obscenely thrust out towards the surprised delivery girl.

"Oh, my god...?!" The busty young woman gawked as she stared at the unexpected appendage, looking every bit as shocked as Emma herself when she'd seen it for the first time less than twenty minutes ago.

Several thoughts passed through Emma's mind at the same time then, and in her confusion she barely knew what she was doing. Somehow her cock was still throbbing with lust and anticipation, wanting only to be buried as deep as it possibly could in female flesh, while the rest of her was mostly horrified about everyone she knew getting to hear about the new assets to her body.

Before either she or the other girl knew for sure what was going on, she'd thrown herself forwards and pulled the brunette into the appartment, then slammed the door shut and locked it behind her back. Then the two of them just stared at one another, eyes wide and lips slightly ajar while they each tried to gather their thoughts again...
