Fucking (alternate)

You knew something was up. "Handicap?" You ask suspiciously.

She nods. "To even the odds. Boys are just better at video games, it's not fair." She pats you again really close to your junk. "What do you say? Give me a chance?"

You play along. "What do you have in mind El?"

"Well..." She begins nervously. "...now that your...you know...available for...you know..." She clears her throat. "Sex! Let's fuck Jesse!" She now begins stroking her rapidly expanding girthy womanhood through her clothes. "C'mon, I want to fuck you . I've wanted it a long time and now there's no reason not to."

"Uh...wow. You're awfully bold about that!" You say with apprehension upon seeing the monster cock outline through her clothes. She keeps rubbing, it was getting stiff fast. She senses your fear and realises that this is all too new for you. "It's ok if you don't want to do it." Elsie says looking a bit dejected but mostly afraid that she might've hurt your feelings. You and Elsie have always shared a strong bond since you were kids. You'd do anything for her. Something had changed in you ever since the revelation. You'd begun looking at Elsie in a new light. You didn't really know what these new feelings were but you knew that you’d do anything to make her happy. "I'll do it" You say. "But please be gentle. It's the first time I've ever done anything like this". Elsie squeals with happiness and crushes you in a bear hug. Her soft body and magnificient tits make you rock hard instantly.

She suddenly pops up and begins piling blankets and pillows in the center of the bed. You stand and watch her, wondering what she was up to. She gets a nice pile when she suddenly pulls down her pants. She asks you to lay down onto the pile so that your ass is sticking up but you are still facing the screen. She is careful to position your small dick just so among the cushions beneath you. She adds a few more cushions underneath your dick to make you feel good as she misjudged your size. She gives you the controller again.

"Ok lets do this!" She says as she squeezes your little ass.

God this family was crazy! But you were horny and ready so what the hell. You look over your shoulder and see her taking off her loose pants and underwear freeing her 10 inch monster, thick as a beer can. You were having second thoughts about this but seeing Elsie so happy changed your mind.

She climbs in behind you. From over your shoulder you could see her big tits , then her beast, then her big balls which were more than twice your size. "Shit... I need to get a condom". She hurries over to her desk drawer and pulls out what looks like a really large condom and slips it on. You now see her applying lube over her cock which she acquired from the same drawer.

She turns and rushes back behind you. She was stroking herself as you instinctively spread your ass cheeks to help her enter. She was surprised with your willingness. Elsie starts applying more pressure to your hole and with a pop she suddenly gets in. As expected it hurt to take something that big but this was quickly replaced with a pleasurable feeling. You look back at her staring at you lovingly. "Just relax a bit". Elsie says. You try to relax as she feeds more of her beast inside of you. Finally you feel her huge and heavy balls tap against your much smaller balls.

"Mmmmm...there we go. Ohh... that's really nice. Mom and Fiona are just so fucking stubborn. They never let me use their ass. And Fiona does not let me use her pussy either." She sighs. "You feel so good big brother." She then hands you your controller once more. She rests her controller on your ass as she starts thrusting her hips, pistoning her thick rod in and out of your ass. You let out an involuntary moan and Elsie giggles. It strangely felt right as her superior nutsack slapped against your much smaller balls as she fucked you.

She starts the game once more. The match is fairly even as you battle on the screen. You hear her sigh. "Ohh...your tight ass is rubbing my cock......big brother, you have no idea how good it feels to have your incredibly hot ass around my cock." You did not realise it but you were moaning like a bitch in heat at this point.Elsie giggled again. "I'm glad I make you feel this way big brother". It was very pleasurable and you wanted more and more and more!! "Ohhhhh...yeah, give it to me Elsie!".

Elsie reaches down behind her and begins fondling both your balls and hers together. "Elsie!" You yelp. "God...you're gonna make me make a mess out of your bedding!". "It's fine. But you'll have to clean it up if you lose." Elsie says with a naughty grin.

You start with the match. She suddenly pulls out her dick with only her head remaining inside. You want to complain about the sudden emptiness but you focus your attention on the match again. Just when it seems that you're about to win she then slams her entire length inside making you orgasm instantly between her sheets.The **** of impact on your ass also makes you loose grip on the controller. She wins Round 1 again. "That's not fair you cheated." You complain. "Well you did agree on a handicap" Elsie grins evilly. Even when she grins like that she looks adorable,you observe. Round 2 takes a while as both of you are distracted. She picks up the pace a bit, her slapping flesh causing your little ass to ripple in response. By your moans and movements she could tell you were getting close. So was she but decided to hold on a bit longer and give you another orgasm. The receiver should always get more orgasms, Elsie surmises. She starts fucking you with inhuman stamina, faster, harder and deeper as she presses her advantage in the game. You shudder beneath her and let out a wail of ecstasy as your on screen persona is knocked out. Your prostate is squashed flat as her fuck stick saws inside your now abused butthole and you have the biggest orgasm in your life. Your ass starts clenching on her massive pole as you orgasm. Elsie shudders at that feeling of your ass clenching and tightening around her hard cock as she whimpers and sighs but she wills herself to hold on and not give in to orgasm just yet.

"Oh my god..." You shudder again. "...you made me cum on the bed.... again" Elsie lifts your ass a bit with her hard length still inside you and gasps as she looks down under you and sees the mess you made under your now flaccid and even smaller looking dick. "What a mess! I never thought you could come so much. And your penis looks really cute in this state". You feel your cheeks burning up at that statement and you look away. Elsie quickly notices this change in your behaviour. "I'm really sorry big brother... I didn't.... I just... I mean it's normal in men....but i'd never...." Elsie looks at a loss of words. But she seems genuinely apologetic. "It's ok Elsie. I've already 'kinda' excepted the fact that I'm the runt of the litter". She seems relieved. Although she mutters inaudibly under her breath. "You're not a runt Jesse".

As you catch your breath she starts Round 3. Having just climaxed you had a clearer head once more, however you were heading over the edge yet again while your little sister showed no signs of slowing down having not even cum once . The fight on screen is a one sided beat down as she fuck you much more faster than you previously thought possible.
