As his finger sunk in deeper, pressing all the way in, as Lexi writhed and moaned and squirmed, Marco couldn't deny that he wanted him badly. He was hard, uncomfortably so, and if he was willing to stop touching Lexi for a second, he would have adjusted himself. But he wasn't willing to do that at all.
"You feel so good," he admitted softly, working that one finger in and out, slow at first but then quicker, rubbing until he felt like Lexi was ready for a second finger. You can't fuck him, he reminded himself for probably the hundredth time. The toy would have to be enough.
The second finger worked in, pressing in deep; his thumb arched around to rub that spot between Lexi's balls - the prettiest fucking balls ever, Marco imagined - and his perfect little hole. Marco knew his anatomy pretty well, knew that if he rubbed with his fingers from the inside and his thumb from the outside, he'd give Lexi something to moan about.
