Matt starts having weird thoughts... his best friend is quickly turning into a simian caveman and is emitting the strongest musk he has ever smelled. However, the musk is starting to become intoxicating. Trying to fight the urge, Matt exclaims "Dude, will you please go take a shower and finish your business?" Ben, obviously worried about Matt losing his patience, gets up and heads to the bathroom. As he shuts the door behind him, Ben quickly strips and finally gets a chance to observe his body' changes in the mirror. Wanting to quietly relieve his erection, Ben turns on the shower and begins to whack off, obviously turned on by his changes so far into a caveman. After leaking what seems to be a cup of precum.
Matt is going crazier by the moment, thinking of his friends smells and how they are turning him on. The bathrooom is emitting a copious amount of that amazing musk that Matt was revolted from just a few hours ago, now he had to get to it at all costs. The thought of being with a man, much less a Caveman, disgusts Matt, but he can't control himself as he quickly strips and runs towards the door. Just as Matt opens the door, Ben blows his load, covering Matt's head and torso with the smelliest cum either guy had ever experienced. Dumbfounded and waking from his pheromone induced trance, Matt freaks out and falls down as Ben tries to help his friend out. "Matt, are you ok?, Ben exclaims as he picks his friend up. "What the hell just happened? This is SO disgusting! I don't even know how I got in here!", exclaimed Matt. "I was watching TV, then blanked out and wake up covered in your simian spunk!!!", said Matt. Stumbling as he left the restroom, Matt says,"I feel strange, light headed. Please grab me a towel and help me get back to the couch."
Ben helped his friend over to the couch. As he put Matt down, he noticed that Matt's brow had become more pronounced like his was 16 hours ago. Not trying to alarm his friend, Ben didn't say anything to Matt until he could figure out what was happening.
