Bored and horny, I invited my buddy Marty over, hoping for some fun. He didn't disappoint. We started with some casual jerking off, his thick cock growing harder by the second. I took the lead, swallowing his length and teasing his sensitive head with my tongue. Marty groaned, his fingers tangling in my hair as I sucked him faster. I could feel his body tense, and then he was coming, his hot, salty cum filling my mouth. I swallowed every drop, leaving me with a mouthful of Marty.
