Call the boyfriend

"Don't show it to anyone"
"Don't wear anything revealing"
"Don't go out in public"
"Don't touch it... anywhere... Don't flirt, kiss, touch or, uh, do anything with anyone"

Her words echo in your mind as you reach for her cell phone.

You think.....

These things are just the start of the payback you have in store for her body.

You think to remember Jeff's number, as you and he used to be buds before he started dating your sister, then realize he's probably on her #1 speed dial.

The phone barely rings when you hear Jeff's voice, "Hey babe, your brother gone to camp yet? Your dad fix the pool filter yet?"

Pool filter, you ponder. You remember dad fixing it two days ago.

You realize that the pool would be the best way to show off this body in something revealing.

"It's fixed" you say over the phone and then you invite him over.

You are all excited at the thought of getting **** against your sister.

You start going through her drawers to find something, revealing, like a bikini. You've never seen her wear them when you were around, but you've seen several in the laundry, and she once caught you taking a peek at them and you got in big trouble for that.

You don't find anything in her drawers, you check the closet and still nothing. You check the laundry room, and there, hanging up drying is the very one you were ogling when she caught you. A basic yellow halter top, and Brazilian cut bottom. You step into the bottoms and pull them up. They fit snugly and feel very comfortable. checking them out in the mirror, you can see a camel toe and squeal with delight.

After fumbling for a while, you manage to get the top on and tied. Looking in the mirror, you play around with your breasts, trying to get the perfect look on her ample chest.

You've always lusted after her body, not in an incestuous way, but as any guy would for a body like this and now you are staring at it in the mirror and it's making you horny.

You were about to get off before when the phone rang, but now you can get to work and see what pleasures this body holds.

Your nipples are now poking out through the bikini top and you can feel a warm dampness in your crotch.

Staring at yourself in the mirror as your hands explore this body, you can't help but get turned on. Your hands roam down to your new sex and begin playing as before, only with more vigor.

You spread your legs a bit and work your hand on your pussy lips through the sheer fabric of the bikini while the other hand fondles your breasts.

Moans of pleasure start emanating from your mouth and you can feel yourself close to orgasm.

This is it, you begin rubbing vigorously. Your legs are getting weak, you go back and lay down on the bed, all the while your hands keep rubbing.

You now plunge your hand under the bikini, touching your moist hot lips. You are panting for breath as the orgasm approaches.

You slip a finger in and begin to wiggle it, when your orgasm explodes. You arch your back thrusting your pussy upwards as your hands plunge in and out, Rubbing and finger fucking your new sex. The climax seems to go on forever, un like when you were a man. there is no instant release, but a constant flood of pleasure building up to a peak and gently flowing back down to a warm satisfied feeling.

You've never felt so relaxed in your life. You sit on the bed, looking at yourself in the mirror, and grab a quick pic with her cell phone to remember the moment.

The pleasured look on your face and the soaking bikini bottoms give it all away. she will know what you did and boy will she be pissed.

The door bell rings.
