Kevin was so into what Megan was doing that he almost missed Anthony undressing. He licked his lips as Anthony stroked himself, then looked down. He smirked as he pulled back all the way to the head, then slid in fully, doing it over and over.
"You should see Anthony," he moaned to her, "He's naked behind us... stroking himself. DO you want to watch me suck him until he comes, love?"
