Milhouse seemed to have lost his shyness, as if his lust for his best friend had taken over his whole body. He thrust as strongly as he could, then retracted until only the head of his cock was inserted in the hole, before thrusting once more. Every time, it sent a shiver down Bart’s spine as he felt himself coming nearer the edge of climax.
It was Milhouse who came first however. In a final thrust, he finally released his semen into his friend. Bart felt every gush of warm juice pouring into him. Instinctively, he clenched his butt muscles so that nothing would escape him. Knowing he was close as well, Bart grabbed his cock and gave it a few strokes. Soon, he was milking all over his stomach. He loved the feeling of Milhouse squirting into him and him shooting his load at the same time, like it was a single jet of cum.
Soon however, the moment was gone. Milhouse took himself out of his friend, panting and rolled on the side of the bed. Bart put his leg back down, still spread and had a big smile on his face. Something came to mind then.
