Harry:
He loves it when you lightly scratch the back of his neck as you make out. He knows that immediately following that move, you'll slide your fingers up into his curls and tilt your hips to his to let him know you want to take things further.
Liam:
The way you hook your leg over his hip as you make out, pulling him against your core and he can't stop himself from grinding against you.
Niall:
He finds it irresistible when you bite his bottom lip softly during heated make out sessions. The light sensation of your teeth scrapping against his bottom lip sends him driving you backwards as he crawls over top of you, eager to scrape his teeth against the rest of your body just as softly.
Louis:
Every time he is sitting on the couch looking rather bored, you always walk over and sit on his lap, straddling him with a smile. With your arms around his neck starring into his blue eyes, it never fails that he picks you up and carries you to the bedroom.
Zayn:
Before leaving his lips after a kiss, you always bite his bottom lip, knowing it drives him crazy.
