I continued plowing her ass, and felt like I could do this forever, when I looked up and noticed the other three girls, Lilith, Madison and Kendall, all standing in front of the bathroom door. They must have opened it without me hearing, and were all three standing there watching me give it to their friend.
All three were naked, including my baby sister, and I just froze as I took in the sight of her naked gorgeousness. This was it, I could tell. This was the moment that all depravity had taken over and there was no limit to what we could do. Kendall's eyes were locked onto me, and I could see that she was more aroused than anyone else right now.
Trish was a bit late in seeing them, but didn't miss a beat. "Oh yeah, watch him take my ass girls! Watch him fuck the shit out of me! Kendall, watch your big brother fuck his cock deep into my ass! Oh god!"
Trish's ass began to quiver as she came beneath me, and her pussy let out a stream of sweet, clear squirt onto the bathroom floor as she climaxed violently. My cock was being squeezed and tugged on so deliciously by her ass that I just couldn't stop myself from blowing into her hot ass, all the while keeping my eyes on Kendall. Her eyes stayed on me as well.
The lotion we had used as lube had begun to dry up, and the friction as I pulled my throbbing dick out of her ass was wonderful. Every last drop of cum was dragged out of me and left coating her insides. Trish moaned appreciatively and rested her face on the cool tile, keeping her ass in the air.
"I win," she sighed, giggling to herself.
"That was so fucking hot," Kendall said. "I just want to fuck every single one of you to death."
"Is it ok to feel this naughty?" Madison asked playfully, fingering herself absently. "That was so bad, what you two were doing."
"It felt so nice," Trish answered. "You want to feel what it's like?"
"I don't know if I can take his cock up there," she responded, but her fingering sped up.
"I'll give you a taste," Trish replied, scooting closer to Madison. "Or rather, I'll get a taste myself."
I watched in fascination as Trish crawled beneath Madison and lifted her chin towards her thighs. Eliciting a wonderfully depraved moan from Madison, Trish began to gently lick her asshole. I could only see Trish's chin as her mouth worked Madison's cute little butthole. My cock wasn't getting any softer by watching this.
"Oh my god, she's eating my asshole!" Madison announced. "It feels so good..."
Lilith had begun to explore her own anal opening with her fingers, and switched back and forth from her pussy and her ass. Kendall was watching and rubbing her mound, but her eyes kept darting back to me and my cock.
"Everyone leave!" she said suddenly.
The other three girls looked disappointed, but then they realized what I hadn't quite yet. That she intended to get naughty with her brother.
They all left the bathroom and Kendall shut the door behind them, but then called to them through it.
"Go fuck each other for a while!"
"Kendall, what is going on here?" I asked.
She went to the sink without answering me, got a wash rag, and rinsed it in warm water. Without saying a word, she bent in front of me and began to wash my penis, gently and lovingly.
"My friends have a tendency to get carried away," she said finally, with my dick in her hands.
"What are you doing, then?" I asked.
She looked up at me. "I know you're worn out, and probably a little sore. But can I just use your dick to get off?"
I nodded, and Kendall crawled onto my lap. My dick felt clean and fresh now, but it had not lost it's stiffness. She touched it gently, moving it around with her fingers so that it found her pussy. I had never thought it would go this far, but now I was about to fuck my sister.
"I'll be gentle," she said, licking my face from my chin up to my forehead. It was a blatantly sensual move, like something an animal would do. "But I won't stop until you cum."
I couldn't help but thrust myself upwards and into her tight little hole. She cried out as I penetrated her all the way, her sopping pussy accepting me immediately. Her head dropped until her head touched mine, and she began to squeeze her pussy around me, milking me without rising and falling. I couldn't stop myself from touching her breasts and her clit.
She responded excitedly when I flicked her little nub, and when I sped up my movements she screamed as a powerful climax exploded from within her. Her pussy shot a steady stream of girl cum all over my stomach, which turned me on immensely. My sister was a squirter! How fun...
I didn't know where the semen came from, but I could feel it boiling inside of me. The circumstance of this whole thing was arousing me beyond belief. I started pounding into her, using her pussy to satisfy my needs, allowing her to derive pleasure from it too but really just fulfilling my wants. I turned her over and spread her ass, driving my cock back into her from behind. As I stuffed her pussy, I started working my finger into her asshole, making her squeal and grunt. This was really happening! I was fucking my sister on the bathroom floor!
"Do you want me to cum in your pussy, or on your face?" I said finally.
"All over my fucking face!" she answered. "You can have my pussy any time you want it, as many times as you want it! But right now I need it on my face..."
"You got it."
I pulled out and she spun around, lowering her beautiful features to the level of my cock. I stroked myself off and let it blow all over her. My cum emptied out of me and onto my baby sister's face, it was so perfect!
Kendall looked so wonderful with my cum all over her. She kissed and licked at my cock before taking it down her throat and holding me there. I twitched and tensed with her mouth
against me, and as she held her there, I felt her finger snake up and touch my ass. I let her explore, actually enjoying it as she rubbed my butthole and teased my entrance. It was so depraved, I think that was getting her off again. She finally pulled back from my cock but licked her finger and inserted it into me. I was shocked at the intrusion, but felt her stroke my prostate from inside and watched as she massaged fluid out of my cock this way. It was quite sexy.
"Did you like Trish's ass?" Kendall asked me.
"Just wait until you try mine..."
I love sleepovers.
