36 Voyeur +18

(Jenna's pov)

'Wonder what is taking her so long?'

She thought, tearing her eyes away from her watch on her hand and back to the movie. [G.I. Joe: Retaliation] which is a great movie, but she wasn't that interested right now as one of the main character is about to die.

So she got up and went to check on her sister, walking up the stairs when she heard a scream.

"Kyaa~"

Stopping in confusion, she looked between upstairs were she heard the scream came from and downstairs with lost of explosions. Her only thought was,

'Huh, I guess they are watching a different movie.'

She begin climbing the stairs once more when she heard Beth said unexpected.

"See something you like, master?"

She instantly froze with one leg raised on the top step as she heard something that she was most certainly not been expecting to hear. Turning her head to her sister's bedroom, she was soon surprised to see the door partially open.

Holding back her shock, she quietly and slowly went up. She was a few steps away from the stairs he heard Alex reply,

"Definitely. Now come here."

It was filled with lust and had a commanding tone to it which made her open her eyes in panic as Beth wasn't like being told what to do. Ignoring how she was turned on by the tone of his voice, squirming in desire to be in her place.

Then, to her further shock and confusion, she'd heard her Beth say,

""Yes, Master."

Shortly after hearing those shocking words from Beth, she made her way towards the door and crack it open wider, so she can get a good view inside. At this point, her heart was pounding rapidly, imagining what she will see.

There before her was one of the most erotic sights she ever saw and left her confused: her sister, wearing a white lacy lingerie with matching stockings, walking towards Alex, who was half naked.

The confusing part was how her breast got bigger in size, it was even bulging from the top.

'How...'

She thought before being thrown out the window as her eyes widen in shock as what she saw next. They were suddenly all over each other, kissing deeply and desperately.

She could tell right away that Beth was the more experienced kisser and Alex was clearly happy to let her take the lead. He massaged not only her sides, but her buttocks and back. Beth pressed into him, rubbing her body instinctively back and forth against his erection.

After a minute of kissing, Beth pulled away first and said,

"Master, I want you to take your large naughty cock and have the wild, steamy mother-son sex on your father's marital bed. Signifying that you own me completely~"

Another shock went through her body at the sound of Beth's low, seductive voice. She had never heard her normally timid sister ever sound so slutty. It was the same voice she used whenever she and her fling were feeling especially horny.

"Aaah, what a dirty woman I am, wanting to disgrace my vows to my husband. But if it's for my master, I wouldn't mind~"

Without even noticing, one of her hands reached down to her wet, clothed pussy. She watch on as Alex said nothing when suddenly Beth dragged his hands to her breast as she continued talking.

"Don't worry, Master...Your toy understands perfectly!"

She watch as Beth squatted down, her legs spread wide and stared up at Alex's cock long, throbbing cock and it was even ;;leaking pre-cum from the tip. She licked her lips, remember the taste of his cum many minutes prior.

Moving her panties to the side, she slowly started to caress her slit. Watching as she let out wet smacking noises around his cock. Low moans were heard echoing throughout the room making her excited. Too excited.

As she was pleasuring herself, a soft moan escaped her lips before she could stop. She froze in panic as Beth suddenly stopped kissing Alex's cock suddenly. She was acutely aware of a single bead of sweat, rolling down her neck as stood up.

Then felt a fresh wave of relief as Beth walk toward the back when she disappeared from her sight. Ignoring Alex who let a a whine that was mixed with confusion.

"N-huh?!"

When Beth reappeared, she was crawling on her marital bed, in nothing, but her white stockings on her feet. Then she spread her legs wide, using her hands to keep them that way. Show Alex and herself her gushing pink pussy.

"I'm ready for you master~"

With a growl from Alex; sending shivers down her spine, he made his way to his mother and sheathed himself in her pussy in one go. Their moans of pleasure made her arousal quickly flared again, demanding her hand back where it was.

Her hands started to move once again, circling her clit over her panty, sending shivers across her body. Then she began to use her other hand and that hand of her's reached for her perky breast under her clothes.

Catching her rock hard nipples with her slightly chilled fingers, the contrast making her shiver. The pleasure started to climb when her other hand found her slit, effortlessly slipping inside her wet folds.

She just stood there, her fingers going in and out, her gaze firmly on two bodies slapping each other at downstairs. She experienced another small panic when another moan escaped her lips; however they didn't hear it.

Thankfully, her moans were drown out by theirs. After all, both of them weren't in short supply when it came to moans, gasps and muffled shouts.

Her hand's started to go in and out faster as Alex suddenly began pounding her roughly into the bed with wild passion. Her hands quickened as she watched Alex's huge cock disappear again and again inside her sister, pushing her towards an orgasm.

Beth was soon spread-eagled, her formerly flat stomach swelling up and deflating with each thrust of him penetrating her. Her thick, muscular thighs extended to either side of his smaller body in a perfect V.

Her eyes were glazed over, her face was radiating bliss as she was staring up into space, a stream of drool running down from her open mouth. Soon loud banging noises was heard with every thrust into her as she could only stare in shock.

"Ohh, fuck~Master, puh-please slow down, you're breaking your toy's pussy in half! Ooo~!"

She screamed. Her gaping vagina was squirting almost continuously, jets of transparent fluid ejected forcibly into the air before they landed on the floor there was a steadily growing puddle of juices underneath her.

Her back was arched and she was jerking spasmodically under the grip of a pleasure she had never seen on her face before. She had to licked her lips, trying to moisten her suddenly dry lips, wanting to experience the same pleasure she is now feeling.

She didn't know how long she stood there, pleasuring herself to orgasms as she watch the two of then having sex. Then she heard Alex screams out,

"I'm gonna cum! I wanna dump my load inside your womb, Toy!"

As soon as Beth that she instantly wrapped her stocking-clad legs around his body, heels locking together behind his bouncing, thrusting butt. Trapping him in place as she could only stare at them in shock.

"Do it! Pump your hot, wet, fat love into my pussy! Give me a creampie that'll ruin me, so fuck your toy like the whore she deserves to be treated as!"

With a final thrust from his cock, Alex creampied Beth as she bit her lips to muffled her own orgasm.

'C-C-C-CUMMINGGGGG!'

She shouted in her mind as she dirtied her fingers and the ground underneath her with her female juices. After such an amazing climax, she crumbled to the floor, slightly chilly surface meeting her steaming skin.

Standing back up on shaky legs, she peek once more inside. Then her eyes widened when she spotted a stream of white liquid trickling from her sister's pussy.

'T-There's... wow, there's so much...'

She thought, dazed by how much he is pumping inside his mother as she thought back to the basement.

'H-how come he didn't cum that much inside my mouth before...?'

Several seconds passed before the stream stopped. Beth's screams had toned down to a squeak as she fell limp on the bed. A few more seconds passed before Alex pulled out of her dripping pussy and laid next to her.

Soon she heard sounds of sucking which left her stunned and in such a state, she didn't notice she had been leaning more of her weight against the door. She yelped in fright when the door suddenly creaked open and she stumbled inside.

Her face immediately burned as bright as her hair the moment she realized the situation she was in. She slowly raised her head to look at the others. Her face turned an even darker shade of red when she saw Alex and Beth staring at her in shock.

"A-Ah... h-hi."

After revealing herself in such an abrupt manner, she wasn't able to properly focus. With her clothes being ruffled by her actions and the wet stain on her skirt. They can guess what she was doing as she watch them a few seconds ago.

Despite that, however, she couldn't deny that what she had just seen was extremely erotic. With her mind occupied, she didn't notice the glint passed through her sister's eye when it disappeared.
