She Had Dared You To Pull Out, So Of Course You Had To.

She had dared you to pull out, so of course you had to.

Your sister asked you how you always got the hottest, curviest girls to sleep with you.  You told her it was because you had the biggest dick around.  Once you had managed to get in bed with one of them, word spread like wild fire.  “I won’t believe you unless I see it with my own eyes,” she said.  After a statement like that, what else could you do?  You pulled down the gym shorts you were wearing and your sister’s eye’s nearly popped out of her head and her jaw almost hit the floor.  It took her a little while to collect herself, eventually she stammered, “It’s huge!!  I never would’ve imagined you were this big!!  Can I touch it?”  You nodded and she reached out and grabbed it.  

As she played with it your cock instinctively started to harden and grow.  “Are you telling me it’s going to get bigger?  Do you mind if I find out how much bigger?”  You told her to go right ahead.  That was when her inner slut came out.  She got down on her knees and started stroking your cock with both hands, licking the head every now and then.  You couldn’t believe this was happening.  Your own sister was down on her knees in front of you fondling your cock and it felt better than any other girl who had done it before.  That was when things got even better.

“It’s SO BIG!!  My boyfriend is big, but I’d be willing to bet you’ve got at least 4″ on him and you’re a lot thicker than he is.  I wanna see what it’s like to be split open by a beast like this,” she said as she stripped, revealing her big, soft, round breasts.  She pushed you down on the couch, climbed on top of you, and slowly lowered herself onto your giant cock.  She gasped as your cock went deeper than you suspected any other cock had ever gone into her and you could feel how wet her pussy had gotten from just looking at you.  After she got down as far as she could, she just sat there for a minute, trying to get used to the feeling of being completely full.

Eventually she started bobbing up and down on your cock, quietly moaning with pleasure as your cock stretched her vagina to it’s limits.  As her body adjusted to the overwhelming size of what had just been inserted into it, she started going hard and faster, forcing more of your cock inside of her.  As the thicker parts of your cock forced their way into her vagina, her soft moans turned into screams of sexual delight that you had heard many times before.  That was when you felt her first orgasm coming on.  Her body went rigid, her breathing became rushed, and her pussy grabbed even tighter at your cock.  That was when you grabbed her by the hips and started thrusting up into her, which was enough to push her over the edge.  She through her head back and screamed in orgasmic ecstasy as her body convulsed around your cock.  Then she went limp and fell onto your chest.  

It took her a few minutes to recover from her mind shattering orgasm, but when she did, she said, “I want your cock back in me right now!!”  You weren’t going to say no, so you told her to turn around and get on all fours on the couch.  She did as instructed and you quickly shoved your cock back into her.  This time you were in control, so you went balls deep on the first thrust, her pussy feeling even tighter than before.  “OH MY GOD!!!  Your cock feels even bigger than before!!” she squealed.  You continued to bury your cock to the hilt, making your sister have a miniature orgasm every time.  After about ten minutes though, you felt the urge to cum start to build.  Your huge cock started to throb and get even bigger and harder.  You knew your sister was about to explode to because her pussy was starting to contract around you.  After a few more thrusts you unloaded stream after stream of hot cum into your sister as she shuddered again in orgasmic pleasure.

After a few minutes you finally emptied your balls and pulled out, your cum dripping from your sister’s pussy onto the couch.  This time it took her almost 10 minutes before she could collect herself.  When she did, she just smiled at you.  “If your not busy do you think you could come by tomorrow?  I’d like to try a few new things…”
