Jeff strutted forward, grinning cockily, holding out his huge tool in his big hand. Chris and Dominic just stared, eyes wide, jaws dropped open. Dom slowly started to thrust again, getting turned on by what he saw. Chris moaned softly, likewise aroused by the sight of Jeff, but confused by it as well. "H- how did you get so big?" he panted.
His massive brother chuckled. "What do you mean? I've always been a huge beast!" He raised his giant arms and flexed them for emphasis, his monstrous biceps rising up high, utterly enormous. He continued to strut toward the two on the bed, his huge dick leading the way, until the tip touched Chris' cheek. "Bet you'd love to get a taste of that..." Jeff purred.
Chris wanted more than a taste. He eagerly licked and kissed the huge head, worshiping the flared helmet until it began to drool pre. But a problem soon arose. As he opened wide to take it in, only the head would fit in his mouth, and only just barely. Chris sucked happily, but Jeff pushed forward, trying to go further, to no avail. Hearing his brother choke as he tried to ram it down his throat, Jeff pulled out. "Be right back..." he said, before turning and walking out of the room.
"Fuck," Dom commented, driving his dick home in Chris' accommodating ass, "Your bro used to be a shrimp! I can't believe that's even him!" Chris could only nod in confused agreement. First Dom changed, and now Jeff? It was a mystery that was becoming stranger by the minute...
Chris had no further opportunity to ponder the strangeness that was around him, as Jeff came sauntering back in, his huge legs rolling around one another as he walked, his giant cock jutting out in front, as hard as ever. Chris opened his mouth wide as Jeff approached, letting out a muffled squeal of excitement as the huge tool slid in, inch after inch heading down his elastic throat until his nose touched Jeff's torso, all of his brother's twenty freaky inches firmly inside him. "Aww yeah, that's more like it..." Jeff growled, as he began to slowly pump his hips back and forth, fucking Chris' improved mouth and throat. His massive body shuddered with pleasure as he felt Chris' extra-long tongue dart out and caress one of his huge balls. "FUCK YEAH!" Jeff roared, thrusting his powerful hips harder, driving his dick roughly down Chris' throat while his balls slammed into Chris' chin, their progress halted only when Chris' talented tongue got in the way. Jeff reached out and grabbed Dominic's shoulders, pulling the other muscleman closer. Jeff leaned in to meet him and they kissed, their tongues wrestling as they sucked on each other's mouths, their hands roaming each other's huge arms and shoulders and chests. Both musclemen fucked Chris with increasing vigor, turned on by each other and by their own bodies. Below them Chris was in heaven, getting roughly fucked from both ends by two massive studs, his emo brain overwhelmed by the pleasure he was experiencing.
