Akihiko and Misaki were at the zoo and stood at the monkeys' cage.
"Aww, Usagi-san, aren't they cute!" Misaki said to Akihiko who was stood behind him.
"Yeah, especially those two over there." He pointed towards some monkeys in the back who where, to Misaki's disgust, mating with one another.
Before Misaki could scold Akihiko for being stupid, he felt his lover grind his clothed package against the teen's rear. "Usagi-san, get off!" Misaki hissed.
"I can't help it, Misaki, they're giving me ideas."
~Five Minutes Later~
Misaki and Akihiko re-emerged from the public toilets, Akihiko with a satisfied smile on his face and Misaki looking completely pissed off.
"Get the fuck away from me, you asshole!" Misaki said, glaring at his lover.
"Oh, come on Misaki, don't pretend like you didn't like it; I had to cover your mouth to stop you from screaming with pleasure."
Misaki gave him one last death glare before storming off, with Akihiko following him, laughing.
I hope I made it clear enough what they did in the toilets. If not, they had sex :P
