Tatum was mostly just in a state of shock. Propping herself up on her elbows as Mack leaned back, she watched closely as the blonde pulled the hoodie off and discarded in somewhere. She hoped her mouth wasn't hanging open or something, but she wasn't really sure either way. Mack looked good, better than Tatum would have even imagined. The older girl had teased her before, threatening to change or strip down in front of her a thousand times in the past, but this was nothing of the same caliber.

Mackenzie Dubinsky was topless. And in her lap.

When it came to real breasts, this was only the second pair she had ever seen. She could hold her own when it came to came to being one of the boys, she had just as much porn hanging around her computer as any one of her fellow bros, but this was completely different, it was real life. This was not only a real girl, but her best friend of all girls.

She snapped out of her daze, eyes only slightly large in the darkness, when Mack spoke to her. Her gaze shifted, from chest to face, and the younger girl managed a nervous little smile. "W-What?" the redhead asked, shifting slightly as her friend began to tug at her shirt as well.

Shit, that was right. When girls had sex with you, you had to be naked too. That was kind of part of the whole deal. Tatum would have much preferred a one-sided exchange, she was more than content to lay back on her elbows and watch Mackenzie as she sat on her half undressed, but the blonde seemed to have other plans.

"Don't like.. f-fucking laugh," she managed, though she did move herself upright, sitting up a bit better in order to squirm her way out of the tee. Once it was off, she gave Mack a momentarily serious look, before reaching behind her back and unhooking her bra after just a few minutes of fumbling. Lesbian or not, those things were a really annoying obstacle to overcome sometimes. At least she had an easier time with her own than she did with Frankie's. It was only luck that the brunette rarely wore one.

She swallowed thickly, bracing herself for laughter, a weird look, something negative. Her eyes searched Mack's face in the way the older girl had done to her earlier, looking for something from her, a sign that this wasn't just a big joke. She was putting her relationship on the line, damaging it terribly, and she couldn't turn back now. If Mack laughed at her now, she didn't know what she would do. Things were too far now.
