Halloween Romp/noticed something was off
Angel stopped when you reached the other side of the street and tugged at her suspenders.
"Ugh, stupid costume! Could've sworn this fit right when I tried it on yesterday..."
You didn't think she was talking to you so you kept quite, instead focusing on not moving your hand and drawing her attention.
You both continued walking down the street past the absurdly large properties. You were still a ways off from the next house and there weren't any other people nearby, so you instead focused on Angel, who was still texting on her phone while tugging at her suspenders every couple seconds.
All of the sudden it occurred to you why she kept fidgeting with her costume. With the height difference between you two you were pulling down on her waistband without realizing it, pulling her suspenders taught against her. You were about to let up when you remembered what happened earlier when you saw her panties and the pleasant feeling it gave you in your pants.
If she doesn't realize what's really happening, then maybe, just maybe, you could use this to your advantage.
What do you do?
