Yep, Cucked by your Sister pt 2

Fuck it! You wanted to get your dick wet.

"I should warn you...about my friend." You say. "He's kinda big."

Allison purrs. "Mmmm...I was hoping you'd say that. Don't worry Jesse, I've had bigger than you. It's all good baby."

You look at Fiona, she has finished undressing and was stroking her monster. It seemed even bigger than you remember. "Okay then." You say.

As you undress Fiona begins running her hands over Allison and sucking her pretty little tits. Your sister is careful to keep her huge breasts and cock away from Allison. She had her hair up in a bun so it wouldn't brush against Allison.

"Mmmmm...you friend has very soft hands. Ohhhh...he really knows his way around a woman's body." Allison moans.

Both you and Fiona put on your condoms, your sister's looks like it could fit your arm. You crawl between Allison's legs, you rub your head up and down her slit a few times then slowly enter her wonderfully tight wet pussy.

"Ohhhhh...I know that cock. Hey baby...mmmmm...yeah give it to me..." She pushes up against you as you start fucking her slick gripping snatch.

You fuck her for a while as Fiona attends to her little breasts and neck and stomach and legs with her mouth and hands. Allison was really getting worked up, as were you! Sensing you were starting to get close Allison gasps. "Wait baby...not yet...let me feel your friend...god he's good with his mouth..."

Fiona had an ear to ear smile. Too late to change your mind now. You back out and walk around to the side. Your sister slathers her pole with a goodly amount of lube and dries her hands on a towel. She takes up position where you had been just moments before. She places her well lubed cock up to Allison's slit. Fiona is staring you right in the eyes.

"Oh...he does feel big..." Allison says as she tenses up a bit.

Fiona grabs the base of her monster with one hand while hold down Allison by the stomach with the other. Still while looking at you she none to gently forces her first four inches or so into your girlfriend.

"Oh....that's...that is big...OHHHHH FUCK!" Allison screams. "FUCK! STOP! STOP! GIMME A SECOND! FUCK!"

Fiona stops, leaving herself about a quarter way in Allison's stretched to the limit cunny. You'd never seen anything close to this as Allison's hot pink labia was taut and tight around your sisters gigantic lubed girth. Fiona bit her lip and swallowed a laugh at Allison's reaction and your amazed expression.

"Oh fuck...Jesus...give me a minute..." Allison is gasping and straining against the bonds. "...fuck Jesse...he isn't big...he's fucking enormous! It's so big, it's sooo big. Fuck he's stretching me so...Just...just...just...oh god...I'm gonna...OHHHHHHHHHHHH GOD!" You stand stunned as Allison is wracked with an orgasm just from feeling Fiona's incredible girth. Her muscles tighten and her body convulses.

She is practically panting as her breathing is rapid and shallow. Allison is talking quickly. "So big, so fucking big. He's stretching me...fuck..." Fiona squeezes a few more inches of her well lubed beast slowly in. "OHHH...God! He's filling me up, I've never felt so full. Oh my god he is magnificent! Okay...stop...stop...fuck...give me a second." Fiona stops again, this time about halfway in and already past were you could reach inside her.

Allison is holding her legs open as wide as she can given the bonds. She has a determined demeanor about her. She grits her teeth and seems committed to taking it. "Whhoooo...whow...okay...Jesus he's not even all in yet...who are you!? Where did you meet a man like this Jesse?"" Fiona stifles a laugh. "How much more Jesse...how much more?" She asks, a bit nervously.

You are beside her slowly stroking yourself to stay hard. "Sh...He's about half way in." You inform her.

"Half way!? You've got to be..." Fiona leans in heavily, cramming another four to five inches in. Allison screams. "FUCK! AUHHHHHHHHHHHHHH FUCK!" Her masked face contorts in pain. "Stop.stop.stop.stop..." She whimpers. "That's it. That's all I can take...FUCK!"

Fiona looked a bit disappointed as she wasn't fully sheathed yet, another two inches and she would have been balls deep. But she stops regardless. She waits a moment to allow Allison time to stretch and adapt. Allison calms a bit and Fiona then begins fucking your girlfriend. Slow long smooth strokes, pulling out half a foot before plunging back in once more. She silently mouths words to you as she does so. 'She's so fucking tight!'

After only a dozen or so strokes Allison is rocked by her second climax. Something about the pleasure mixed with pain of being stretched and pressed to the limit has her cumming fast and furiously. "OH FUCK!" She screams. "I LOVE THIS BIG FUCKING COCK!!! OHHHHHHHHHH!" In the whispered panting gasps just after the orgasm she sighs. "Fuck...I'll never be the same..."

Fiona then really turns up the intensity. She fucks your girlfriend deeper, harder and longer than you ever could. She takes Allison over the top time after time after time. Allison kept screaming and talking. She would say things like. "Who are you? You're the best...the fucking best!" and "I've never felt like this before! So full, so full!" and "Tell me who you are! Please!" and "This body was made for your huge cock you fucking bull stud!"

It is close to four when Fiona finally lets loose. With impressive control and silence, probably developed during the previous years of keeping the family secret from you, she just lets out a low grunt as her massive balls shoot their load up Allison's hole. Allison's body goes loose, she is a sweaty and her breathing erratic. She just moans. "...ohhhh...ohhhhh...you're the best ever...ohhhhh..."

Fiona pulls her cock out of her fuck toy, your girlfriend. Allison gasps at the sudden emptiness of her gaping cunt. Fiona slaps her anaconda down on Allison's stomach, giving you a sense at just how deep she had penetrated. Jesus! Peeling the massive condom off her member Fiona holds it up for you to see the size of her load. Then she drops it unceremoniously into your bedside garbage bin...gross!

She whispers in your ear. "You'll never satisfy her now...bitch. Your little pencil dick belongs to the family now, don't forget it." She gives you an evil wink, picks up her clothes, then leaves the room.

Allison moans. "...don't go...I want to meet you...ohhhhh fuck..."
