I don't own South Park.
It was a sunny Wednesday in august and there were only a couple of days left before summer vacation, therefore a few students showed up at school that day. Because of their strict mothers, Stan and Kyle had to attend school. Neither Kenny nor Cartman nor any of their friends were obliged to come and besides them only the ugly kids and the Goths were listening to Mr. Garrisson's boring talk about ancient Egypt. In the end of his talk, he told the students to write an essay about it in pairs. Kyle grouped up with Stan automatically. Ky started to write. Stan gazed into Kyle's eyes, but he looked away and continued with the paper.
Stan put his hand over Ky's lap. They exchanged a long, deep look. Kyle understood. With the other hand, Stan wrote "Handjob?" in his notebook. Kyle nodded. Stan made his way into Kyle's pants, silent and carefully, rubbing Kyle's length over his underwear, caressing it while looking into his green eyes. Stan entered his underwear, feeling every inch of Ky's increasing cock. He massaged the head for a while, Kyle bit his under lip, trying to avoid being loud as usually. Stan started moving his hand up and down, rubbing and feeling Kyle's hard cock. Kyle moaned with the eyes. A party under the desk. He looked at Stan. He wrote "CUM" in the paper. Stan threw his eraser on the floor and pretended to go catch it, but he quickly opened Kyle's pants and pumped his hard dick faster while he quickly licked the tip of it. Kyle was biting his lip so hard it was almost bleeding. He came in Stan's mouth, who grabbed the eraser on the floor and put Ky's cock where it belonged. The boys exchanged another look. Finally, Kyle wrote "my turn".
