Tag Teaming Melanie

The two of you stalk down the hallway like predators on the search for prey. You first come to Rachel's door. You lean in and put your ear to the closed door. Nothing. Silence.
"Must be Mel."
Tommy grins stupidly at you.
"Heh, well, she does have bigger tits, so I guess that's a bonus."
You leave Rachel's door and head further down the hall. As you approach the end of the hallway, you can now clearly hear the shower running.
"Perfect."

Tommy walks up to the bathroom door and waits eagerly for you.
"Come on, man! Let's do this!"
He's obviously very excited about the idea of fucking Mel. You step next to him and open the door. A hot mist pours out of the top of the open door and you both creep inside. The glass doors on the shower are fogged up, blocking your view of Melanie's naked body, but also blocking her view of the two naked, horny perverts busting in. Tommy steps in behind you and slowly closes the door again. You quietly creep up to the shower, you at one end and Tommy at the other. Through the thick, fogged glass you can now make out the shape of your sister. Then you slide open your side of the shower.

"Ah!"
Melanie screams as you startle her.
"Jesus David, you scared the shit out of me."
She moves her hands to cover her nipples and steps back into the shower head. You enter the bottom of the shower and stand naked in front of her.
"You don't mind if we join you, right sis?"
You grab her and pull her into a tight embrace. Your hard dick slaps up against her thigh and pokes into her stomach. You reach around and grab an ass cheek and give it a firm squeeze.
"Umm, I guess not. Wait, what do you mean 'we'?"
As if on cue, Tommy opens the other end of the shower and steps in behind her. He grabs her hips and begins running his hands up and down her sides.
"You remember Tommy, right? He stopped by and we thought you could help out us a little."

Tommy grabs a handful of Mel's wet hair and tilts her head to the side. Then he leans down and begins sucking and biting on her neck. Mel closes her eyes and lets out a sigh.
"That's it. Just relax, babe."
You tug on Mel's arm and she uncovers her breasts. You take hold of her wrist and guide her hand down to your cock. She wraps her fingers around your dick and begins slowly stroking it. You reach back up and begin groping her huge breasts. Tommy sees your initiative and grabs Mel's free hand and guides it to his own cock. She begins stroking him as well. You release her breasts to grab the side of her face. Leaning in, you kiss her and slowly start probing your tongue into her mouth. Tommy seizes the opportunity, and reaches around her to grab her breasts. He lets out a moan as he begins placing and teasing her nipples. You decide to move things along and gently press on Melanie's shoulders, leading her down onto her knees. Tommy steps back to let her kneel down and when he does the water splashes over his shoulder, splashing you in the stomach and Mel in the face.

"Heh, hey man, turn that thing down so it's still making steam but isn't drowning our toy here."
Mel kneels down across the bottom of the shower while Tommy fiddles with the shower head. You grab one tit and turn her head to face your cock. She looks up at you, licks her lips and takes you into her mouth. You grab her head and slowly fuck her face. Mel starts moaning around your cock. Tommy turns back around after fixing the shower and immediately grabs Mel's other tit. He pinches her nipple, twists it, then flicks it with his finger. Seeing you are gonna be a while, he squat's down next to Mel and takes her breast into his mouth.

"Suck me, Mel."
You begin thrusting deeper into your sister's mouth. She takes each thrust like a champ, even moaning louder as you fuck her mouth. Then she does something you didn't expect and slams her head down your shaft, deepthroating you herself.
"God damn!"
She comes back up for air and sucks the head of your cock like a crazy woman. That's when you look down and see Tommy has two fingers working her pussy. You give him a stupid grin and a thumbs up. You keep fucking her face, pushing into her throat every few thrusts. Melanie begins shaking as Tommy fingers her hard and fast. You start getting more aggressive, slamming your cock into her throat. She start gagging on it but doesn't stop. Then Melanie screams into your cock and her eyes fly open. You look down and Tommy has his other hand fingering her asshole.

Seeing this is too much for you, you grab Mel's head and under her chin and then savagely fuck her throat with your massive cock. She grabs onto your thighs to stop you, but with little effect. You cram more and more of your dick down her throat. You back off just enough for her to suck in a breath, and then slam your dick home again. You feel your balls churning and hold Mel down on your cock. Your first shots go right down her throat. Then you pull back and fill her mouth. And finally, your last rope blasts her right between her eyes. You see her swallow a few times and then cough and spit out your cum. Tommy continues to furiously finger her cunt and ass. Once she regains her breath, Mel goes back to panting and moaning. Tommy bears down on her clit and she cums on his hands.
"Uh, fuck, rub my pussy, just like that, keep going!"
Melanie's orgasm lasts a few long seconds and then she slowly comes down off her high. Tommy removes his fingers and stands up.

You step back and watch for what Tommy does next.
