Magnus was the last person to care about size when it came to a relationship, believing that a person's body should dictate what was yearned for by either heart or soul. Their sex life was as balanced as their marriage, and while Magnus was no stranger to being the one in Alec's lap, he'd had more than his fair share of toned legs straddling his thighs as well.

Humming happily at the brush of Alec's nose and lips against his face, Magnus reached an arm around him to slip a hand into one of his back pockets. "You don't know that, precious," he said, still marveling at how Alec failed to notice attention when it was turned in his own direction; for someone so astute, Alec missed some obvious observations. "I'm glad to know that your size is as much a factor in your faithfulness as your marital status," he teased, squeezing his ass through the jean pocket.

He sucked in a breath when Alec's teeth grazed the shell of his ear, only half able to concentrate on following the design Alec was drawing. Luckily, the powder kept it intact, and he smiled as he looked down on it. "Mine, but also your own." He never wanted Alec to feel like he was a possession, even if the mix of alcohol and powder brought out a possessive side from Magnus.
