Lucy weaves her fingers firmly into Peter's hair, returning the kiss and pressing up against him, then insinuates her leg between his, hitching up her skirt a bit in the process.

After a little while, she lets go of him (though doesn't pull away or really stop kissing) to reach down and lift her skirt and pull down her underwear. Stepping out of it and lifting her leg to pluck the panties off one ankle, she then tucks them into the front pocket of Peter's leather jacket with a grin.
