Which Betrayal?

"I missed you," Anastasia confessed as he rubbed Xavier's arm that was wrapped around her neck, keeping her in place as he cuddled her from behind.

"I missed you more," he replied, kissing the top of her head as he breathed in her scent.

Anastasia chuckled lightly, rubbing his arms even more gently as she smiled in satisfaction.

Xavier had returned after spending a few weeks away from home, dealing with a certain person who kept killing innocent people. 

When he returned earlier, he found Anastasia in the shower. Unable to resist, he got into the shower, filling her up from behind—making the shower turn steamy. 

As if that wasn't enough, he lifted her and rushed to the bedroom, filling her up once again, arms wrapped around each other, unwilling to let go unless they'd had their release.

After their steamy night, they slept. The next morning, Xavier got a boner and they continued from where they left off.
