I dropped to my knees the second he unzipped, staring straight at that thick black cock and the heavy pair of balls swinging underneath. They were smooth, dark, and full, hanging low between his thick thighs. I leaned in without a word and pressed my face right under his shaft, breathing in the hot, musky smell of him. My tongue came out and I licked the left ball first, slow and wet, dragging across the skin until it tightened up a little. He grunted above me and spread his legs wider. I opened my mouth and sucked one ball inside, rolling it on my tongue, feeling the weight of it. Saliva ran down my chin as I worked it, sucking harder, pulling it in and out of my mouth with wet sounds filling the room.
His cock twitched against my forehead while I switched to the other ball, sucking it the same way, letting it pop free with a loud smack before I went back for more. I used both hands to lift his sack and bury my face deeper, licking the skin between his balls and then sucking them one after the other again and again. He tasted salty and strong. I moaned around the mouthful and started jerking his cock with one hand while my mouth stayed busy on his balls. Spit coated everything. Every time I sucked hard he pushed his hips forward, driving those balls deeper into my mouth.
I let them both rest on my tongue at once, stretching my jaw wide, sucking and slurping like I was starving for it. The heavy weight filled my mouth completely. I could feel them shifting as I pulled harder, drawing long, sloppy sounds out of my throat. He reached down and grabbed the back of my head, holding me there while he rocked his hips, rubbing his balls across my open mouth and chin. Pre-cum dripped from his cockhead onto my hair but I didn’t care. All I wanted was to keep sucking those black balls until they were shiny and dripping with my spit.
I pulled off just long enough to say, “Fuck, these balls taste good,” then dove right back in, sucking the left one deep again and humming around it. He groaned louder and started stroking his own cock above me, the head brushing my forehead with every stroke. I kept at it, alternating between long licks and tight, wet sucks, making sure every inch of his sack got attention. My own dick was rock hard in my pants but I ignored it, focused only on the way his balls felt sliding in and out of my mouth.
He told me to suck harder and I did, hollowing my cheeks and pulling one ball in until it almost touched the back of my throat. Spit poured out around my lips and down his thighs. I switched fast, sucking the other one just as deep, then tried to fit both again, pushing my tongue between them while I sucked. The wet, filthy noises got louder. My jaw ached but I didn’t stop. I wanted him to feel how much I needed those balls in my mouth.
He started thrusting a little, sliding his balls over my tongue while he jerked faster. I kept my mouth open and ready, catching them each time they swung forward, sucking hard on contact. My hands stayed on his thighs, holding on while he used my face. Every few seconds I pulled back just enough to lick the underside where his balls met his cock, then sucked them back in. They were getting tighter now, drawn up a bit as he got closer. I sucked even harder, making loud, greedy sounds, letting drool run everywhere.
When he finally came he aimed his cock down so the first thick ropes landed on my tongue and the balls I still had in my mouth. I kept sucking through it, swallowing what I could and licking the mess off his sack afterward. His balls were covered in cum and spit. I licked them clean, slow and thorough, making sure nothing was left. He stayed standing over me, breathing hard, while I finished the job, giving each ball one last soft suck before letting them slip from my mouth.
I sat back on my heels, chin and chest soaked, and looked up at him. He smirked and wiped his cock across my lips one more time.

“Good boy,” he said. I just nodded, already thinking about the next time I’d get to drop down and suck those black balls again until my jaw gave out.
