I Catch My Stepbrother Masturbating, So I Help Him with a Blowjob

I walk into my stepbrother's room and catch him with his cock in his hand, stroking it fast. He tries to hide it, but I tell him not to stop. I want to watch. Then I decide to help him out. I drop to my knees, pull his pants down fully, and wrap my lips around his hard dick. He moans as I bob my head up and down, taking him deep into my throat. He's got a thick cock and I love the way it fills my mouth. I suck his shaft, lick his balls, and then deepthroat him until he's panting. He grabs the back of my head and starts fucking my face, pushing himself all the way in. I don't gag, I just take it. My chubby body and big ass are on full display as I kneel there, and I know he's loving the view. He tells me he's about to cum, but I don't pull away. I keep sucking, and he shoots his hot load into my mouth. I hold it all, then swallow every drop. I open my mouth to show him I took it all. He's surprised and impressed. This isn't the first time we've done this, and with the way he's looking at me, it won't be the last.
