Your Sister... and her boyfriend

You open the shower door and reach for the towel but it isn't on the hook. You look to where the silhouette is standing and see Gwen through the steam. She is standing there holding your towel with a curious and slightly sinister look on her face.

"May I have my towel please?" You ask.

Gwen replies, "You mean MY towel? And just who the fuck are you and what are you doing in my shower?"

"Gwen, listen. I can explain." You begin but she cuts you off...

"Answer my questions! Who are you and what are you doing in my shower?!" She almost shouts.

You hear footsteps running up the stairs and think that Isaac is back and will help you explain. Your hopes are dashed when Randy, Gwen's current boytoy, runs into the bathroom, almost colliding with Gwen. "Hey babe! What's wrong? Who are you...? Whoa!" He says as he looks in your direction and sees you in all your naked glory. You try to cover yourself with your tiny hands and again plead with Gwen to give you the towel. The cooling water on your skin was beginning to cause you to become chilled and you could feel your skin getting all covered in goosebumps while your nipples were hardening in the air conditioned air. Gwen lifted the towel high out of your reach and spoke to Randy, "I found this 'thing' in my shower and she won't tell me who she is or how she got in here. And would you looky there? She has some of my underwear laid out to put on. This skank is just a common cat burglar come to steal my stuff. Tsk tsk tsk, bad pussy cat! Maybe we should tie her up and call the cops, huh babe?"

You gasp at hearing your sister mention the cops and then shudder when you see Randy's face as he appears to be imagining tying you up. He says, "We do have those special items in your closet. They should restrain her quite well until we decide what to do with her." His menacing smirk causes another chill down your spine and a tingling between your legs. You think to yourself, 'OMG! Is the thought of being tied up turning me on?! I have to say something quick.'

You blurt out, "Gwen it's me, John!" and quickly recount the story of how you came to be in this predicament. You leave out the part about Isaac and the risk of pregnancy because that would be way too embarrassing. Like the fact that you're standing naked and dripping wet in front of your sister and her boyfriend isn't embarrassing enough.

Gwen and Randy stare at you slack jawed as you finish your tale and then they slowly turn their heads to look at each other before they both begin laughing. "Oh boy! That's a good one! My little brother is so going to pay for this little stunt. But I have to hand it to him. He does have quite the imagination. And he somehow got a very pretty girl to go along with his prank. Is he paying you or are you just as demented as he is? No matter. You need to pay too." She then turns to look at Randy and said, "Grab her!" And before you can react Randy pounces on you and wraps his muscular arms tightly around your naked body. He straightens up to his full height and you find your feet almost a foot above the floor. Gwen motions for him to follow her as she goes back into her room.

You try to protest and struggle as Randy easily carries you into Gwen's bedroom. Gwen has pulled a box out of her closet and motions for Randy to put you on her bed. Randy drops you unceremoniously onto the bed and before you can react he has your arms pinned above your head as Gwen snaps handcuffs on both of your wrists and attaches them to the headboard. You begin to writhe and scream at Gwen when she produces a ring-gag from the box and pushes it between your lips, securing it behind your head. "There now. A little peace and quiet while we work. We'll have you wanting to tell us where John is soon." She says with an evil laugh.

Meanwhile Randy has been busy securing your ankles to the posts of the footboard so that you are spread eagle on your sister's bed. Gwen and Randy stand back and admire their handiwork with hungry expressions. "Hmmm, she looks good enough to eat, eh babe?" Gwen says to Randy. He smiles and nods, "I think I'll let you have that fun while I feed her some of my meat stick."

Hearing the conversation between Gwen and Randy you start to worry how far they'll go, _'Oh God! I am in big trouble now! I hope Isaac gets here soon. Before things go too far.' _You renew your efforts to get them to release you and to let you explain. Your attempts to speak sound more like moans of pleasure than you intended.

"Ooh babe, I think she likes that idea. Look at how wet she is. She's practically gushing" said Gwen.

Your eyes go wide with shock and realization that Gwen was right that your pussy was a virtual flood of fluids. 'Is this really turning me on? What does that mean? Am I into bondage and submission?'

As you are distracted by your musings about the implications of your body's reaction to being bound and at the mercy of your sister and her boyfriend, they have been busy undressing. You are shocked out of your utter trance by the feeling of the bed shifting. You look towards the foot of the bed to see Gwen with a wolf-eating look on her face crawling towards your exposed pussy. You start to shake your head and try to protest as you feel and see Randy straddle your torso with his bare cock exposed. You notice it is hard and thick and bigger than average. Maybe 7 or 8 inches long. He places his hands on your breasts and squeezes them around his shaft while his thumbs begin to press and tweak your nipples. As he starts to thrust his cock between your breasts you feel Gwen's mouth start to rain kisses upon your inner thighs as she works her way towards your hot, wet pussy.

Soon you shift from protesting to truly moaning at the pleasure your sister and Randy are giving you. You start to buck your hips into Gwen's face as you lift your head up and line your mouth up for the head of Randy's cock to hit your lips and tongue when he strokes forward. You taste his precum on your tongue. Gwen lifts her head up to say, "OMG Babe! She tastes so sweet and her pussy is twitching and sucking my tongue inside her. She is so wet that I bet you could slide right in without any resistance."

Randy replies, "Damn babe! Between this slut's mouth and your words I am getting even harder and won't be able to hold out much longer."

Gwen says, "Mmmm, you should definitely try dipping your cock into her tight, hot, wet cunt and stroke it a few times before you cum and miss this opportunity."

Randy says, "Let's switch places so I can feel that tight cunt wrap around my cock and squeeze and milk me. But I gotta be careful because I am SO close!"

Gwen giggles and replies, "Maybe you don't be careful and dump your load inside this dirty skank! It would serve her right if you knocked her up for conspiring with my little brother to pull that prank on me."

Your eyes almost bug out of your head at hearing their words knowing what that would mean for you. You didn't see the shared look between Gwen and Randy with the unspoken message. You begin to struggle harder against your bonds as Randy moves between your thighs and lines his bare cock up with your unprotected pussy. Gwen laughs as she straddles your head and lowers her wet pussy onto your mouth. Just as she starts grinding on your face you feel Randy push into you with one long stroke. It seems agonizingly slow and you can feel every inch invade your tight snatch. Your pussy is absolutely gushing now despite your fear of lasting consequences. You can hear Randy and Gwen kissing as you feel hands on your breasts, tweaking your nipples. Randy is all the way inside you now and you feel so full. You can feel his swollen balls resting against your ass as he pauses inside you. You can feel his cock pulse and twitch a little inside you and you know that he is very close. Completely helpless beneath them you have resigned yourself to your fate.

Randy begins to slowly pull out and your pussy seems to be squeezing his cock in an attempt to keep it inside you. 'Damn! My own body is betraying me!' you think as you feel Randy almost completely out of you now. He suddenly plunges back in with a **** and speed that utterly left you breathless. Gwen seems to be picking up her pace as well and you can hear them both panting and gasping with the exertion of their activities. Randy is downright grunting and howling as he slams his cock in and out of you like a wild beast. You feel yourself bucking your hips up to meet his thrusts as your sister seems to be nearing her peak.

You feel her pussy gush out rivers as she screams and falls onto the bed beside you panting and writhing in ecstasy. You now have a clear view of Randy as he pounds away at your pussy. His face is red and his breathing is labored and you can tell that he is trying so hard to hold back so you can experience an orgasm before he finishes. You feel your body is primed to explode and he is the detonator as his wonderful cock slams in and out of you. Rubbing your most sensitive places. And then it happens. You feel the most powerful orgasm you have ever felt wash over you. The feelings overwhelm you as they effect every part of your body. Electric tingling can be felt from your scalp to your toes. This is unlike anything you have ever before felt. You scream through the gag as you hear Gwen egging Randy on, "Do it! Shoot your baby batter into her! Spill your potent seed inside her womb! Knock this nasty, sneaky, little slut up for pulling that prank! Do it!"
