She knew what she was doing was wrong, it was morally sinful and according to her father she'd burn in hell for eternity.
But those thoughts couldn't be further from her mind when her lips collided with the petite brunette's.
Just one kiss and she was addicted, Rachel Berry was her weakness and they both damn well knew it.
She tried to pass off their first kiss as a mistake and they agreed it wouldn't happen again, the next day they ended up in a heated make out session that still to the day neither one is sure who started.
Each time it happens she swears it won't happen again but they both know it will.
They crave each other in a way that goes beyond anything they've ever known.
One touch is all it takes for them to cave in and end up flushed and sated.
They were shy and timid their first time, but now they'd give Brittany and Santana a run for their money.
All Rachel has to do is catch Quinn's eye in Glee Club and she knows that as soon as everyone is out of sight she'll be backed up against something with the blonde wearing a familiar smirk.
At first it was just physical, purely sexual need. But both parties' feelings grew very quickly and just a few weeks in they agreed that they only needed each other.
They went out on dates, though admittedly they found it hard to keep their hands off one another, they were still in the glorious 'honeymoon' stage of their relationship.
Both girls had smiled so much during their four months together that they were sure Santana would class them 'disgusting' like she could talk though; her and Brittany were love sick fools too.
Rachel found it so hard to believe that Quinn loved her back but she proved it to her by showing her at any opportunity she could.
Lingering touches, songs in Glee and driving to her house before school with vegan friendly breakfast.
Her ultimate declaration of love? Making their relationship public at Mckinley by kissing her in front of the entire cafeteria.
Love is their welcome addiction. Their drug of choice. They're proud addicts.
