My girlfriends sisters - Part 3

This is the third part of this story, to understand the context please go back and read the first 2 parts. This is optional, but it will help you understand more if you do.

Emily swung the door open, coming home from her day of college. She looked at Angelica, my cock in her mouth. Then looked at Grace, who was watching. She didn't look at me.

Angelica took my cock out of her mouth, and said "its not what it looks like." Even I knew that was probably the most stupid thing she could've said in the moment.

She stepped closer in a strangly calm manner.

"Not what it looks like? To me it looks like you just took my boyfriends load in your mouth, with our underage sister watching. Is that not what it is?" She stepped closer to me, and looked me dead in the eye.

"You are sick."

She stormed off upstairs, and I was at a loss. Everything was running through my head, but not one was an idea.

Angelica wiped the rest of the cum from her face and onto her clothes, then sat on the couch with her head in her hands. Grace was bright red, and just sat on the couch staring into space.

After about 10 minutes, I decided to go upstairs and try to talk to Emily. I knocked on the door.

"Honey?"

No response. I gulped, fearing for the worst, and took a step inside the room. The bunk bed to my left blocked the view of the left of the room, so I reluctantly took more steps into the room, each one with more dread than the last.

When I finally stood in the room, Emily gripped me by the shirt.

"You truly are sick. But the more I think about it, the more it turns me on. So, fuck me, here and now."

I quickly got fully erect again, and within seconds she was fully naked, bent over her bed.

I put my cock on the slit, trying to find the entrance, before she reached back and pushed it inside her. I started moving my hips, back and forth, still feeling guilty about what she walked into.

"Are you going to just stand there or are you going to fuck me? Get on with it!"

I gripped her hips, and slammed deep into her. The feeling of guilt left, and all that was left was lust. I thrusted into her as hard as I could, my cock penetrating her cervix every time. The neighbours banged on the wall, so her moans could easily be heard from downstairs. Both Angelica and Grace ran up the stairs and into the room, and I stopped.

"What the fuck are you doing? Don't stop just because they're there, I was close!" Emily shouted. I carried on, as hard as my body would let me, ensuring to put on a good show. Emily's moans grew louder, the neighbours banged harder against the wall, and Angelica and Grace were both masturbating.

Finally, she reached her climax. Her pussy tightened, her legs straightened, and her fists gripped the bedsheets so hard her knuckles turned white. Like a chain reaction, Angelica screamed, her legs closing tight around her hand. Grace was the opposite, her legs spread wide, her hand sped up, and she squirted all over the carpet.

I stood in shock, trying to process what had occurred. I pulled my cock out of Emily and rested it on her back, still hard as a rock.

"Give them what you gave me." Emily said quietly. Without waiting, Angelica assumed the same position at the side of the bed, using her hands to spread her thighs wider. I slipped my cock inside of her, and started thrusting hard, giving all the energy my body had left. Emily flipped over, lying on her back, and Grace sat between her legs.

"I always wanted to try this." She said, and started licking Emily's pussy. I watched in amusement, and Angelica orgasmed a second time. I pulled out of her, a small pop as my cock came out, and Angelica and Grace swapped positions.

This was it. I was about to fuck a 14 year old. I was terrified, and yet so excited. I slid my cock inside her pussy, tighter than both of them even during orgasm. She screamed, and I moved slowly. As my hips retracted, there was a trace of blood on my cock.

I put my hands on her hips, slid them up her waist and around to her chest, where I could feel her B cups perfectly fitting into my hands. I moved slowly, and she tightened with each thrust.

Emily came once again, gripping Angelica's hair tight as Angelica furiously masturbated, moaning just as much as Grace.

It wasn't long before Grace orgasmed again. Her juices poured like a river down my cock, slowly dripping from my balls. Angelica moved over to me, sucking Grace's juices from my balls. I could feel my own orgasm on its way.

"I'm gonna cum"

Emily bounced into action. All three seemed to want it, but she announced priority.

"My boyfriend, my load."

She put my tip in her mouth and stroked my cock with vigor. I moaned loud, and shot my entire load into her mouth. She swallowed the entire thing, same as she had done many times. Angelica looked upset.

"I wanted some!" she protested.

"I don't like the taste, but I wouldn't have minded if some got on my face at least." Grace wasn't too upset, she just seemed envious.

I sat down on Emily's gaming chair, and continued processing what had happened.
