Marcus' eyes widened when he realised what Cassius was about to do and now he couldn't think of anything else besides Cassius' hot mouth on him.
"Ohfuuuuck," Marcus groaned when his lover sucked him in. He grabbed the edge of the table so hard it should have cracked, as he resisted the urge to thrust into Cassius' mouth.
God, it felt so good... of course he'd had his cock sucked before, but never like this. Just looking down to see the other man on his knees was almost enough to bring him off, and now what he was doing to him... all he could do was moan Cassius' name and grab a handful of his thick dark hair.
