Fucking my Wife's sister... in front of her.

Carla pushed herself up once again and with no ceremony whatsoever lowered her sweatpants to the floor. She was wearing nothing beneath, and my eyes roamed over the soft light colored patch that marked her pussy, the lips invitingly parted, just a tad.

"So, Brent, Mind lubing up for a couple strokes?" Carla smacked her sister's ass once again, bringing a groan from Kaila.

I immediately took the hint, and grasped Kaila's hips with my hands. My exposed cock slapped neatly between her cheeks, and the groan in response was everything I needed. I shoved my now aching cock into my wife, and reveled in the near scream of pleasure that emanated from her lips. I thrust into her, once, and then again...

"That's enough..." Carla's hand on my chest pulled me backwards for a bit, and I felt my cock pull free of my wife. The wet feeling of her lubrication on me remained, and I felt Carla's teeth at my ear.

"All nice and wet for me..." Carla purred. "I always wanted to do this..."

Carla pulled me backwards towards the couch as I heard a frustrated grunt from Kaila, who now had half turned to watch me and her sister as we moved. My pants slipped over my hips almost of their own accord, and Carla fell back onto the cushions, pulling me atop her as she did so.

"Gonna fuck you right in front of her..." Carla grinned at Kaila, before her gaze returned to me... "Fuck me..." A nearly feral growl issued from her lips, before Carla's fingers in my hair pulled me down for a deep and passionate kiss, her tounge demanding entry into my mouth as my cock found that perfect notch in her body.

I was surrounded by her heavenly pussy in seconds. Aided by the copious amounts of her sister's lube on my cock, I easily slid into her and her gasp in response was everything I needed.

"Yeah, fuck me..." Carla moaned loudly. "You know how good he fucks, Kaila... you know he did this to me all night long last night..."

"Now you're just being mean..." Kaila complained. I glanced over to note that her thighs were tightly pressed together now, as she watched her sister and I thrust against each other, hard and fast.

"Fuck... you gonna knock me up too?" Carla grinned into my face. "How many innocent women have you violated this week? How many poor defenseless wombs have your sperm in them? Daddy..."

The word seemed way more attractive than it had any right to be. The image of Helen and Kaila, both with full bellies. was more than I could really handle. I felt the stirrings of my orgasm starting already.

"Fuck, Carla, slow down, or you're going to make me come..." I warned her, to Carla's renewed motion beneath me.

"Uh-uh... I want to show my sister how fast I can make her stud come..." Carla grinned at me, before kissing me urgently. "Want to show her how much her husband likes my pussy... How much he likes giving me a baby..."

That did it. Carla's dirty talk was hitting all of my hot buttons in quick succession, and I felt the seed racing through me. I thrust into Carla deeply, unable to resist the urge to come, and felt the first pulse of my come flowing into her.

"Fuck... Carla..." I moaned her name loudly, right in front of my wife, which brought a soft sob to her lips. I was shocked at the reaction, and noted that there were some tears on Kaila's cheeks. I couldn't stop coming however, and the combination of exhilaration, concern and lust for Carla all combined to cause me to lose track of almost everything save the the feeling of hot willing woman, and incredibly intense orgasm. The sound of Carla's voice joining mine in moans told me she too had reached her peak as I spurted into her again and again. For a second her voice almost seemed to come through in stereo.

"Is... it... totally weird I just came while crying?" Kaila spoke quietly as Carla and I panted against each other. I looked over at her to notice that she had much more obvious tear marks on her face now. "I mean... I thought... I hated it....but I loved it. I loved watching that.... Oh, I'm sick..." Kaila shook her head softly, her hands pulling on the rope. "Ok... so... you two made your point..."

Carla's breath against me suddenly caused a pulse to flow through my lower body. I mean... why was I still hard? I had just come inside a gorgeous willing woman, and yet... the image of my wife, so wet, so aroused, and yet so in need of comfort brought a sudden lust for her to run through me.
