20 minutes later

You weren’t sure where you found the patience to wait that long. You did half heartedly update some research notes and read over data sent through by your colleagues. Even Brynn had come through with new findings on the formula. There might be some tweaks to the inject for effectiveness in more people.

Your erection was in effect currently. You shut the laptop and stood, taking a breath to steady your nerves, and tried not to be creepy as you crept your silent way to the hall. You could see a dim sliver of light through the gap Leslie had left open of her door. There was a conscious decision not to hold your breath but to keep your inhalations and exhalations controlled and quiet as you tiptoed closer. You stopped with the cold wall to your back and closed your eyes, standing by the door now, taking a moment. Then you very carefully took a peek.

They were going at it, your mother and your aunt. The sisters were on the bed, on top of the sheets, completely naked, on their sides and locked together. They kissed like they needed to breathe through each other’s lungs, your mother’s hands caressing Aunt Les’s cheek, jaw and neck while the career lesbian was busy getting knuckles deep between her sister’s thighs. You couldn’t quite make out your mother’s pussy with the light and shadow but you definitely could see the motion of your aunt’s fingers curling in and out of her. You realised you were squinting to try and see it, to see your mother’s pussy, and all the psychology in the world didn’t matter to you in that moment. You got a hold of yourself, slipping a hand beneath your waistband, sighing quietly.

Patricia’s moans were growing louder as Leslie worked her. You could tell she was trying to stifle it, but the instinct to keep quiet was getting overtaken by other desires.

“Ohmygod Les, fuck me… yes… fuck me…” she whispered urgently, her occasional gasps silenced by muffled moans and wet smacking lips. “Les! Urhhnn! Yes!” she squealed breathlessly as she came, body curving around your aunt’s hand that continued to rub the good spot. You watched your mother orgasm, the curvature of her ass accentuated by her bend. You were fixated on the rise and dips of her body now glistening with sweat and tried not to stroke yourself too fast. Her body finally relaxed after long sensual seconds and you saw your aunt still restless next to her, licking and kissing her neck as Patricia giggled. That’s when Leslie lifted her head slightly and her gaze tracked over to the door. Your heart skipped a beat as you locked eyes with your aunt, the woman smiling that devilish smile of hers.

“I’m not done with you,” your aunt told your mother, shifting onto her knees and moving up the bed. Your mother laid onto her back, had no idea you were there, entranced by the glorious nakedness of your aunt just as you were. Those tits defied gravity and those thighs were wide and welcoming. They were positioned around your mother’s head now, that glistening lesbian pussy slowly lowering towards Patricia’s waiting mouth. Leslie watched you at the door with her smile, then reached over to something that had been obscured by a pillow. The purple dildo waved at you as if to say hello and your aunt closed her eyes for a moment to enjoy her sister’s mouth. Then she leaned forward, running her hand down your mother’s swelled tits, smooth stomach then to her legs, parting them. Your view was direct and well lit. Your mom’s dripping pink snatch was pointed right at you and then Leslie’s dildo flopped down onto those lips.

“Are you ready for this?” asked your aunt, her eyes never leaving yours. You saw her arching her back slightly, easing her pelvis off your mother’s face so she could take a breath.

“I’m fucking soaked, Les,” moaned your mother. “You know I’m ready.” You could tell by the way your aunt bit her lip that your mother was now back to hungrily eating pussy, and you could also see the subtle gyrating of Patricia’s hips as she rubbed herself against the tip of the dildo.

“Mmm…” sighed your aunt, as she spread your mom’s lips with one hand while changing her grip on the dildo with the other to get it ready. Your aunt was right. God your mother had a beautiful cunt. So pink. Mouth watering. Then it was filled as Leslie slid the dildo in. You gripped onto yourself tighter as you imagined unsavoury things while watching scandalous reality. You could hear Patricia’s moans though the muff muffling her and it was fucking music. Les fucked her, increasing the pace steadily, playing your mother like an instrument. Patricia didn’t slack off either. The faces your aunt was making were unmistakable and she couldn’t quiet her groans as miniorgasms fluttered up her body. “Mmmm Patty…” she moaned, still thrusting the fake dick in and out smoothly. “Ohmygod yes… that’s the spot...ahh…” Your aunt’s eyes locked with you again. “I’m gonna cum Patty… oh fuck…yes… ohhnmmm...” And then she did, legs squeezing together and squishing your mom’s head in that heavenly vice. She held onto the dildo still half buried in your mother’s cunt as she convulsed. You wondered how long Patty would be able to hold her breath, and you thought that she may have been in some trouble when she started to kick her feet. Then you heard your mother’s gasp, Leslie slipping forward off her face as she dug the dildo in deeper. Your mother was climaxing again, her sister still squirming on top of her, your mother’s legs shaking. They were a wet and sticky shuddering mess as the orgasms rolled over them and you realised you had to stop before you blew your load. You let go of yourself, your hand claw-like for a second, then took a deep breath as your cock cooled off ever so slightly.

Still observing the pair you saw your aunt move herself back into a snuggling position with your mother. They were back to kissing, your aunt licking and tasting all over Patricai’s face to sample her own flavors. There was contented humming and after a minute or two the fondling slowed and a sheet was pulled over them so they could sleep. Your mother nestled her head under your aunt’s chin, a smile on both of their faces, but Leslie still had a half-open eye on you. She winked then shut her eyes. You wondered what you should do. You weren’t sure you would be strong enough to wait another 20 minutes. You slid down and sat on the floor, your back still against the wall next to the door, your cock still standing at attention.
