Ha på mig min flickväns trosor, styvsyrra?

I was horny and looking for anything to feel connected to a woman.. The first thing to come to mind was panties! So I snuck into my stepsister's room to try to find solace.. But was caught during my naughty escapade! What are you doing in my room!? I thought I left something in here.. -But sis saw right through my lie when she noticed the pink lacy fabric in my hand- Are those my underwear?! I swear it's not what it looks like! Thats so gross I'm gonna tell stepdad your messing around with my panties! No please let me just explain..
