"I, uh, what?" asked Matt, blushing.
Cole could see Matt's dick getting hard in his pants. "Come here, Matty" he said.
Matt was almost helpless to obey. The awesome display of masculintiy that his brother had become compelled him towards Cole.
Cole stood up from the bed and ordered Matt to worship him. Cole hit an impressive double biceps pose for his brother. Matt's hands reached up to feel the massive peaks. Almost more than the size, Matt was struck by the hardness of them. Matt could feel the blood pumping through Cole's engorged veins.
Next, Cole moved Matt's hands over his massive pecs. Matt let out a little sigh as he tried to grasp Cole's chest. His thumbs began to fondle Cole's nipples.
"Suck on them." Cole commanded.
At this point Matt was only too happy to oblige. He moved his head down and alternated sucking on his brothers delicious erect nipples. Cole began to breathe harder and his cock was now needing attention.
Cole put his hands on his brothers shoulders and forced Matt to his knees. This time no words were needed, Matt happily pressed his lips to Cole's large, and getting larger by the second, member. Cole let out a very loud groan as he forced Matt's mouth over his thick cock. Despite Matt's gagging and weak attempts to come up for air, Cole face-fucked him with ferocious intensity.
It didn't take long before the tingling returned to Cole's body. His already sore muscles began to swell again and his cock was growing too massive to be held by his brother's throat. Cole began to scream as he pulled out from Matt. The screaming continued as the cum started to fly.
Matt looked up at his brother in complete awe and worship. Cole was growing taller, his muscles impossibly more swollen and his cock and balls spasming violently in an almost unending orgasm. Cole's eyes rolled back into his head as he fell backwards onto his bed. Matt was briefly pulled out of his funk and remembered he had the same pill as Cole in his own room...
