Breaking their intoxicating kiss, Leo touched his forehead on Becca's, literally hearing how fast her heart was beating in her chest.
Becca was once again left breathless and gasping for air by him.
She felt a little nauseous so wrapped her arms around his neck to stabilize herself and though it was just a small gesture, it made Leo's heart swell with joy.
Such a small gesture but meant quite a lot.
Becca was finally taking the first initiative to do something so intimate with him. She trusted him so much to the point she was using him to stabilize herself. She knew he wouldn't let her go, never let her fall.
Besides all that, Leo was mostly happy because he was with her and she wasn't rejecting his touches, instead she was touching him as well.
She loved him touching her and Leo would gladly give her more, way much more.
