Your bonus-mom who you have a deep bond and feelings for and.. also innapropiate thoughts about wanted to show you her new dress she bought for her Anniversary date with your dad...

She stands upstairs and calls your name walking down slowly and your jaw almost drops with a slight heart flutter. She walks down with a red dress covering her lower body mostly but her upper body is only covered with red cloths from shoulders towards the middle of each breast where it's very revealing of torso and hips.

Mom: "What do you think of this dress honey?"
