Scorpius had been worried at first, really worried. He knew how he had felt, and how nervous Lori was, but once those fingers hit the right mark, the look on his boyfriend's face shifted. He kept his hand on Lori's cock and added a third finger, stretching him as much as he could, knowing that he was still bigger.
He made sure to hit that spot a few more times, before withdrawing. His smile broadened and he came back for another long kiss. "I can't wait anymore," he whispered huskily in his ear, kissing that little spot behind it that he liked so much.
Sitting back up, he took the lube and spread it over his cock. He pushed his boyfriend's legs up further, positioning himself correctly. He caught Lori's lips again, and pushed gently against his entrance. He didn't want to drive in too quick, but pressed in and out gently until he was there completely. This was the most uncomfortable and he took a moment to rest before he got overly excited. "Merlin, you feel so good," he whispered against his lips, beginning to move.
