Steve glanced at Bucky, uncertain what to do. Bucky gave him an encouraging nod—he should make the first move. Steve took a deep breath, taking Peggy’s hand. “You sure you want this?” he asked.

As she turned to Steve, Bucky saw her worry and concern melt away. “Oh yes,” she said, holding his face and kissing him. A slow kiss, gentle with love and feeling and desire.

Bucky watched Steve kiss her in return—his lips, his tongue, his hands. They were stunning together, and then they turned to look at Bucky.
