My GF Sister and I Part 3 [MF]

It’s been a while since my last story, but I think what I’ll tell you guys next will make up for the delay.

A few weeks after the last events I planned a dinner in my apartment with some friends, my girlfriend and of course her sister. I set it for eight at night and got a message from my girlfriend’s sister saying that they would arrive before the rest of my friends around five in the afternoon. I agreed and waited until I decided to take a shower.
A few minutes later I heard the noise of the front door opening, I turned off the shower went to the room to get dressed, when I turned my back to the bedroom entrance I felt someone grabbing me from behind and putting her hands over my body slowly going down, I was extremely truned on…
I almost jumped when she whispered in my ear – “Waiting for me?” – When I turned around, it wasn’t my girlfriend but her sister. She pulled me and kissed me, she looked extremely horny and went down with her mouth down my neck with both hands on my back. When she said she was coming I deduced that she was coming along with my girlfriend, but I was completely wrong.
She was taking off her own clothes as she ran her mouth down my body until she was on her knees, threw my towel away and grabbed my cock with desire starting to slowly masturbate me while looking up smiling. It didn’t take long for her to start licking all my cock, very slowly teasing me as much as possible, she increased the speed, using her tongue very well, driving me crazy.
That’s when my cell phone started ringing, I glanced over and saw that it was my girlfriend and I had to answer, when I tried to turn around her sister held me, I still managed to reach the phone and answer while she continued sucking me. I tried my best to have a normal conversation with my gf on the cell phone, but her sister blowjob was delicious and I could only give short answers so my girlfriend asked if everything was okay, while her sister stuffed my whole dick in her mouth. With a brief sigh I said yes and filled her sister mouth with my cum, but my cock was still hard…
She swallowed everything and when I signaled that I was going to turn off the phone she looked at me with a malicious look and asked me not to turn it off, she threw me on the bed and climbed on top of me, rubbing her wet pussy on my cock. I tried to keep the conversation going on the phone, then felt my cock entering her pussy, she started to go up and down on my dick, really fast and really hard, I could hardly stand to continue.
Her ass and breasts swayed as I fucked her horny slut sister and suddenly she let out a loud moan, my girlfriend seemed to notice something, but luckily she couldn’t hear well and believed me when I said it was the television. Finally I hung up and we both started laughing as I got up throwing her bed reversing the position.
I fucked her for a few more minutes until I came in that delicious little mouth, my girlfriend was hot but looking at her sister was even better. I got ready and she took a shower, before we went to the room I got another blowjob. The rest of the night went on without any surprises.
Would you like me to tell you about my girlfriend too? Or just go on about the sister?
