Kiss her

As soon as Marcie finishes talking, you wrapped your arms around her and pushher against the wall of the elevator. She stares at you with wide eyes for a moment as you tilt your head slightly and lean in to kiss her. By the time your lips meet, you can feel her hand rubbing at your crocth through the front of your pants. Your own hands slide down to her big ass, squeezing.

You are so caught up in making out with your twin sister that you almost miss the eleveator door when it dings open on your floor. You manage to reluctantly pull yourself away from her at the last second and catch it.

"If you hadn't done that, we might have had to use the emergency stop button," she said with a giggle.

Marcie snuggles up next to you as you step into the corridor, and you slide and arm around her, placing your hand on her ass. She looks up at you and smiles, and you can't help but lean in and kiss her as you walk. Somehow her hand finds its way back to your crotch and gives your manhood a firm squeeze through your pants.

At last you arrive at your room. The two of you can't stop kissing and groping each other long enough to open the door, but somehow, after several attempts, you manage to fumble around with the key and get it on the lock.

When the door swings open, you drag her inside and slam the door closed. You push her against the wall again, and this time she lifts her legs and wraps them around you. Your hard cock grinds against her pussy as you dry hump her against the wall.

After several minutes you put one hand under her big ass and another between her shoulder blades and lift her off the wall. All of her weight presses down on your erection and you moan into her mouth as you turn and carry her to the bed.

When you are in position, you sit her ass on the mattress and she unwraps her legs from around you. Your hands immediately go up her shirt, pulling it over her head. As soon as its off, she does the same to you. You then lean back down and kiss her as you unfasten her bra. At the same time she is undoing your pants.

Marcie shrugs her bra off and you let your pants fall to the floor. This time your sister breaks the kiss and leans down to free your cock from your boxers. Before they even hit the floor, she wraps her lips around you. You gently massage her shoulders as she slides all of you into her throat and begins bobing up and down your shaft with her hot, wet mouth.
