First Kiss (Patreon)

This scene is set even earlier than the last one, taking place when Beth had just turned eighteen. One night Lauren came home tipsy and horny after a bad date, only to hear some very distinct moans and sighs coming from Beth's room.  Lauren creaked the door open slightly to find her younger sister masturbating in bed.  She couldn't help but watch until Beth noticed her and beckoned her into the room.  Lauren sat down on the bed, expecting to talk but was surprised when Beth suddenly kissed her. Things went as you might expect from there.
