"Don't stop on my account!"

Gwen was openly leering at the two of you for a few seconds in silence before apparently blurting out the first thing that came to mind. It takes a few more seconds before she apparently realizes what she just said, or perhaps more importantly, exactly who she said it to. For a moment she's quite flustered, blushing and shuffling back and forth. She manages to recover somewhat, though, adding "I'll just go wait in the bedroom, and you two can come and get me when you're done in the bedr-... I mean, you can get me when you come in the... I mean... um... Bye!" The whole time she was speaking, she had been inching toward the bedroom door, and with that last exclamation she practically dives the remaining distance, slamming it shut behind her.

Allison rolls off of you and onto her back on the floor. After a brief recovery, she starts giggling to herself, and you can't help but join in. Still, you manage to stop her before it turns in to full laughter - it would be pretty bad if Gwen could hear you laughing through the door. You kiss her Allison softly on the lips, but the moment has clearly passed. You definitely aren't ready to have sex with your sister in the next room, perfectly aware of what you're doing.

You reach for the discarded t-shirt, but Allison stops you and instead directs you to the pair of shopping bags next to the door that you had previously overlooked. Right, her note did say she'd buy you new clothes.

You open up the bag closer to you, which seems to be the larger of the two, and look inside. There seems to be a whole outfit inside. There's a pair of jeans, a bra, a halter top (at least, you think that's what it's called), and a pair of sandals. You're no expert in women's clothing, but it looks like a cute but casual outfit. Oh, and there's a whole pack of panties. How considerate.

As you open the packaging to get a pair, you turn to Allison and ask in a hushed tone "are you sure this stuff is going to fit me?" She nods, but apparently doesn't feel the need to elaborate further. Eventually you decide to prompt her again. "And what makes you so sure?"

Somewhat hesitantly, she replies "well, you're a really heavy sleeper, and I have a tape measure here in the apartment..." She trails off.

It takes you a moment to realize what she's trying to say. "Seriously?" you ask as you pull the fresh panties up your legs, and Allison silently nods. Apparently your girlfriend took measurements of your naked body as you slept this morning. And judging from how embarrassed she seems about it, she must have at least copped a feel while she was doing it. You find that highly arousing. Lately, you seem to find just about everything arousing.

Allison helps you put on the bra, and you stop dressing for a moment to pull her into an embrace. You want to let her know you're okay with her feeling you up while you slept. You also want to thank her properly for being such a considerate girlfriend... but that will have to wait for later. "What's in the other bag?" you ask, as you resume getting dressed.

"That one's for later," Allison answers, in a tone that suggests an exciting surprise is in store. It probably can't top the surprise from last night, though. As you finish up, Allison walks to the bedroom door. She grabs the handle and starts to turn it... but nothing happens. Apparently, Gwen has locked it from the inside. Allison looks annoyed by this discovery - which makes sense, you suppose, since this is her apartment. She grabs a key from it's hiding place behind a bookshelf and opens the door without knocking. You're standing right behind her as she does, and over her shoulder you see...
