Steve was straining forward as The Bull backed off, not wanting to let go of his birthday present, eager to keep sucking. He had an idea what was coming next though. Steve relaxed and stared lustfully at the huge cock that had been pounding at his face for the last ten minutes. It was visibly throbbing and clearly ready to give Steve exactly what he knew was coming and what he was more than willing to receive.
"The Bull's ready baby, are you?" Stacey asked. The patronising tone was still in her voice, reminding Steve of his total submission to the situation. He turned to face her and saw her wry smile as she looked down at him. She had stopped stroking his dick and was squeezing it now, grinding her palm on the head. The feeling was intense and almost uncomfortable. He squirmed a little and knew that he had no control over anything at all that was happening.
Unable to speak Steve simply nodded at Stacey, his expression a mix of desperation and resignation to what was going to happen. Her smile deepened, she ran her fingers through his hair and turn his head back to face The Bull's cock. It was still throbbing, still rock hard, still huge and waiting to release.
Stacey kept her hand on the back of Steve's neck and spoke to The Bull.
"Pump him full of cum." She instructed.
Immediately The Bull complied, thrusting his enormous long dark brown cock into Steve's mouth with more force than before. He was slamming it into the back of Steve's throat and pulling it all the way out again. Over and over, all the way in and all the way out.
Stacey had started stroking again. Long, fast and hard strokes. She knew Steve was close to cumming himself as his hips and legs were writhing violently and he was moaning constantly.
After a minute of this frenzy The Bull stopped with his cock right against the back of Steve's throat. It happened in an instant but Steve knew exactly what was going on and he experienced it in slow motion. His head was held in place by Stacey's hand.
The Bull's legs trembled slightly. Steve felt a heavy pulse run through the base of the thick dark shaft resting on his tongue. A hot rope of cum forced it's way directly down his throat. A second followed immediately after.
The Bull pulled back so the huge throbbing head was just inside Steve's mouth. Steve sucked hard, he wanted it all and he was getting it.
Stacey echoed her previous command in a low whisper "Pump him full of cum, pump him full of cum."
The Bull did exactly that. A huge blast of warm spunk covered Steve's tongue. Another followed, and another. Wave after wave squirted into his mouth. Steve lost count but there was a lot. Each one a hot jet delivered as powerfully as the last.
Steve's mouth was filling up. He was amazed how many times and how consistently strong The Bull could eject the streams of cum into him. Just as he was beginning to think there would be too much for him to take it stopped.
The Bull kept his cock in Steve's mouth. It pulsed strongly every few seconds and Steve enjoyed the sensation. The Bull slowly started sliding his cock up back and forth over the length of Steve's tongue. The warm cum moved around his mouth mixing with his saliva. It felt amazing. Steve whimpered. He felt like he would explode.
"Swallow it, there's a good boy" said Stacey.
Steve sucked on the big black cock in his mouth and let the huge pool of cum slide to the back of his throat. As he started to swallow he also let loose his own seed. It squirted on his stomach. Several modest lines of hot cum shot out violently and he groaned loudly. He had never orgasmed so hard.
The Bull slowly withdrew. Steve opened his eyes and once again took in the dominating sight of that enormous cock. There was a lot of cum still on it.
Steve was breathing hard. "Well done baby" Stacey said. "Clean it up". She continued to rub the head of his now limp dick and the feeling was on the pain/pleasure border. It kept his submission to Stacey and The Bull in mind.
Steve opened his mouth without hesitation and The Bull laid as much of his long dark shaft as he could on Steve's waiting tongue.
Steve passionately cleaned off the rest of the cum, sucking at the tip trying to get every last drop from it. He enjoyed the slight give in the still impressively thick shaft as The Bull's massive erection subsided.
Steve felt The Bull start to pull out for the last time. He wrapped his lips as tight as he could around the big cock as it slid from his mouth. He didn't know if he was trying to make sure it was perfectly clean or keep it in place.
The Bull turned and walked out of the bedroom with his back to the couple. Steve watched longingly at the several inches of black cock clearly visible, even from the back, hanging between The Bull's legs. It was still a powerful sight and far bigger than Steve's when erect.
Stacey turned his head back to face her and kissed him hard. "Happy Birthday baby" she said again, still rubbing his sensitive little dick.
Steve shuddered again. He closed his eyes and laid back. The taste of cum was still in his mouth and the sensation of The Bull's massive thick black cock pounding his mouth over and over again was burned into his mind. He couldn't stop thinking about it.
