Watch for a while.

"Oh yes John!" Rachel gasps as she lowers herself onto the penis of her blonde lover, both of them completely unaware of your presence as watch them with your mouth open wide in shock, with your gaze firmly locked on Rachel's thick erect cock inbetween her supple legs.

"Oh yes!" Rachel moans contentedly once she has completely impaled herself on Katie's own member. Rachel gazes down at Katie adoringly, and starts to grind herself on Katie's member, drawing out sounds of lust and pleasure from her lover's lips.

Rachel gasps aloud when Katie wraps her hand around Rachel's thick erect cock. You watch in amazement as Katie is barely able to wrap her dainty hand around Rachel's thick shaft, before proceding to stroke it. Low moans escape the back of Rachel's throat as Katie jerks her off.

"I want you to ride me like the slut you are, Rachel. I want you to cum on my cock." Katie hisses.

Rachel wipes the beads of sweat which had gathered on her brow with the back of her hand, before nodding her head emphatically at the blonde underneath her. Rachel pushes herself upwards then sinks herself back onto Katie's cock. Rachel places her hands on Katie's chest, drawing a moan from her lover as she caresses and fondles the blonde's own impressive boobs. As a result her arms are pressing her round, juicy tits together ever so slightly, while she begins to ride Katie, bucking her hips as she impales herself on her lover's member time and time again, her breasts shaking softly between her arms and her erect cock slapping against her stomach.

"Oh God, John!" Rachel cries out, unaware of your presence while Katie doesn't appear to mind Rachel calling out your name, instead of hers. Instead Katie clasps Rachel's legs tightly and uses her hips to thrust her cock deep into Rachel's juicing pussy.

As you have been watching this incredible scene your conciense has been fighting a losing battle. Your conciense has been screaming at you to get out of the room, but your thoughts have been unable to penetrate the fog of lust and confusion that has clouded your brain.

"Fuck yes John! Fuck me!" Rachel cries.

After one last look at Rachel's beautiful face, and seeing the lustful grimace plastered on it, you glance down at Rachel's huge tits bouncing and shaking wildly as she rides her lover's cock. As you slowly back and retreat into the hallway your eyes dip towards Rachel's cock, oozing pre-cum before closing the door to Rachel's bedroom as quietly as you can.

Once in the hallway you slowly tip-toe across the landing towards the staircase.

"Oh fuck,John!" Rachel shouts once you reach the staircase. "You're going to make me cum on your cock!"

Every step towards the landing and away from the bedroom feels like a major effort, as your throbbing cock is screaming at you to join the two women and get in on the action.

Once downstairs you make your way to the kitchen, and pour yourself a glass of water before sitting down in one of the chairs by the table. Your thoughts are a whirl of shock, lust, anger and love. Your thoughts turn to the events of the past few weeks. Despite the use of hindsight, you can't recall any clues that would reveal Rachel's 'big secret'. Despite the constant banter and teasing Rachel always has kept her distance when the two of you threatened got close.

"Oh FUCK Y-Y-Y-Y-E-E-E-S-S-S!!!!!" Rachel's cry of ecstacy reverborates throughout the house.

Your thoughts turn to the chain of events that transpired this morning. Less than an hour ago Rachel was suffering from a serious hangover, and looked like she was on ****'s door, but right now she was upstairs recieving the pounding of a lifetime from her seemingly estranged friend who lives in their home town an hour or so journey away.

Rachel and Katie have vaginas as well as penises, which meant they weren't shemales- meaning they were never men. You have heard of rare cases of people being born with both sexual organs-making them hermaphrodites- in Far Eastern countries, but never in this country.

With your mind still in a mess, you make your way to livingroom and turn on the tv before sitting down on the sofa, **** for any kind of distraction.

......................................................................................................................

"Hello? John?" Rachel's calls from the top of the stairs twenty minutes later.

"Yeah, its me, Rachel." You reply. You deduce that she has heard the sounds coming from the tv.

"You're home early." Rachel states. You detect a note of worry in the tone of her voice.

"I've only been home a few minutes." You lie. "Couldn't really get into the mood for a work out. How are you feeling?"

"Better, thank you John". Rachel replies as she walks down the stairs.

You stand up and make your way to the hallway. You note that she is fully clothed, and bar the flushed state of her cheeks you couldn't tell that she had only recently been having sex. Your eyes slide down to her groin, looking for any visible sign of her secret.

"Well, well, well." A soft voice calls from the staircase. "This must beJohn, the person I've heard so much about."

Both you and Rachel glance upwards towards the source of the voice and find yourself looking at a very familiar blonde making her way down the stairs. Rachel's blushing intensifies at Katie's words.

"Er, hi. Y-you must be Katie." You say awkwardly. "You staying long?"

Katie's face twisted into a lewd smirk. "No, I think we are done here, aren't we Rachel?"

Rachel's face turns to a bright shade of betroot, before nodding slightly. "Yeah, I'll see you soon Katie.

Rachel and Katie hug each other a little longer than you would consider friendly before Katie gives Rachel a peck on the cheek.

"See you soon, Rachel." Katie says, her eyes roam over your body. "Bye John, nice to meet you."

"Er, bye." You reply before Katie exits the house via the front door.

"John?" Rachel calls out after several moments of silence. "Are you ok?"
