Talking with a group that she had shared a particularly nasty professor with Kristina didn't even notice Derek was near her, and even after they bumped she didn't know who it was. The bar wasn't that crowded yet, so there hadn't been much physical contact. She realised that there was someone close behind her, her butt brushing their body, maybe their thighs. Then the warm skin of a hand seeped through her shirt and Derek's voice followed. Breaking away from her conversation she turned her head and gave him a little bit of a scowl, "It's her birthday dumbass. Did you forget that you were driving or something?" she replied and went back to her previous conversation though her body didn't break the contact between them.
