I just got home from the gym with my stepbro and notice him staring at my sweaty armpits. I know he's got a thing for my armpits so I decide to tease him a little bit. Peeling off my sweaty shirt to reveal my bare armpits, licking them as he grows more and more excited. We move to the couch and he begins fucking me missionary. He can't control himself and quickly cums inside me even though he knows I'm not on birth control. Since we've already done the damage, I beg him to fuck me again, pushing the creampie deeper inside my wet pussy. I love feeling my brother's cock pounding me harder and harder until we both cum while he shoves his face in my sweaty pits.
