Rin waited in her room quietly, shyly crossing her legs as the door opened. The male quickly closed it, turning to face the girl. As blue eyes met blue he went to her, kissing her neck
"L-Len..."she squeaked "remember if the others realize what we are doing it's game over"
he looked at his twin lovingly "Then lets make sure not to wake 'em" he muttered, kissing her sweetly. Rin wrapped her arms around the boy's neck
"Len... I love you" she whispered as she came up for air. "daisuki dayo" Len ran a hand up her leg, pushing her down and kissing her again, licking her bottom lip. she allowed his tongue to slip into her mouth, easily dominating her own tongue as she mewled a little, breaking for air. Len sucked on her neck, leaving huge red and purple hickeys all over her neck and collarbone.
"I love you" he muttered, nipping at the sensitive spot on her neck, making her whimper. she was getting louder and louder, Len too busy to notice. he slid his shirt off, untying the back of her nightgown and tugging it over her head, leaving her in her bra and underwear. he slowly ran his hands down her sides as she whimpered and mewled.
Miku walked down the hall, hearing a sound. she peered into Len's room. empty. she turned to Rin's room. yep. definitely that room. she opened the door innocently
Len smirked, looking her in the eye as he grabbed a bra strap, teasingly pulling it down and kissing her shoulder. at that moment light flooded into the room and a gasp was heard. the 14 year old twins looked at the silhouette of the blue haired girl. the girl stared back with her mouth hanging open. they were too shocked to move. Len was the first to recover, throwing his shirt over Rin, running over and slamming the door in Miku's face. Len put his shirt back on, sleeping on the floor, still slightly shocked. from then on Miku never looked either of them in the eye again.
