My big ass Latina stepsister catches me in her panties while I'm masturbating in her room and then she lets me put my penis in her nice, tight ass

My big ass Latina stepsister, Lupe, stormed into my room, slamming the door behind her. I was caught off guard, my hand still buried deep inside my pants as I watched her tight little body clad in a lacy thong move angrily across her bedroom. She turned around abruptly and saw me staring at her panties-clad ass in disbelief.Lupe's eyes narrowed dangerously, and she quickly unhooked her bra, letting it fall to the floor. My dick throbbed in anticipation as her plump, round ass cheeks came into view once again. Without saying a word, she grabbed my hand and roughly pulled it out of my pants, squeezing my throbbing erection between her fingers."You like what you see, hmm?" She smirked, running her calloused fingert ips lightly over the head of my cock. I swallowed hard, unable to tear my eyes away from hers as she slowly began to stroke me through my pants.
