My girlfriend and I were partying with my best friend at my house when my best friend got up to grab another beer and When he was walking by my girlfriend sitting on the couch she leaned forward and ripped down his sweat pants. He jumped forward and she pulled him backwards, which wasn’t very hard considering he only weighs about 150 lbs and is 5’6″. He spun around and lost his balance, almost landing on top of her. We were all laughing until we seen his HUGE COCK flopping right in front of her face and just stared in shock and disbelief. My girlfriend said “Holy shit! That’s the biggest dick I’ve ever seen!” He pushed off the couch and ended up right next to her with his sweat pants down around his ankles and his huge cock hanging out and laughing. My girlfriend asked him how big was it when he completely hard and he told her “Grab it and find out.” She looked at me and asked me if she could? I was still in shock and told her “Go for it.” She reached over and started stroking it and smiling at me, asking me if “Do I look hot with his huge cock in my tiny little hands?” All I could do is nod my head yes and stare in disbelief. She told him to stand up in front of her and started stroking it with both hands. His cock started getting longer and bigger as he’s looking down at her and smiling with his massive head starting to swell up inches from her face. She asked him how many inches it was and he said “11” when I’m rock hard, but I’m not there yet..” My girlfriend looked at me and asked me if she could get it rock hard and I said “sure”. Before either of us knew what she was about to do she leaned forward and stuffed the head of it in her mouth and started sucking on it while stroking it with both hands. She looked at me and pulled her mouth off of it and with a huge smile asked me if she looked hot with her lips around the head of it? I couldn’t believe she was practically cheating on me with my best friend RIGHT IN FRONT OF ME! I was hurt, confused, jealous and really confused as I started getting rock hard watching her. She started sucking on it really hard and fast grabbing his ass and pulling his massive hard on into her mouth as far as she could. Next thing I know I’m watching my girlfriend sitting on the edge of the couch and deep throating the whole thing all the way to his balls! His eyes rolled back in his head and he said “No one has ever been able to do that with the whole thing before!” My girlfriend looked up at him and asked him “Does your girlfriend suck on it this good?” He couldn’t even say anything as she started slamming the whole thing in her mouth over and over. She pulled her mouth off of it and looked at me and asked me if “Do I look hot sucking on your friends huge dick?” I just nodded yes and couldn’t stop watching her. She stood up and grabbed him by his dick and told us to come into the bedroom. She pushed him down on his back and told me to lay on the other side of him and start jacking off watching her. I was rock hard when I pulled my dick out and started stroking myself. She kept watching me and smiling as she was stroking it with both hands and sucking on his balls. Sliding her mouth up and down his shaft from his massive head to really tight balls. She told me to kiss her and When I leaned over she grabbed his cock with one hand and then pushed my head down on his raging hard on with her other hand, laughing and telling me to suck on his head! I tried pushing up but I was at an awkward position with no leverage. She kept rubbing his head across my lips and telling me to suck on it. I kept turning my head away and telling her NO but she said she wasn’t going to stop until I at least put the head of it in my mouth for just TWO Seconds. She told me that I may as well do it because she’s rubbing it across my lips anyhow and kept trying to shove it in my mouth. I noticed that he was just laying there laughing and smiling with my girlfriend rubbing his head across my lips and totally letting her do it. I finally agreed to do it only if she let me up after I did it and she agreed. I opened my mouth and she pushed my head down on his raging hard and shoved as much of it in my mouth as she could. Then she let my head up and I thought she was going to let me up when she’d push my mouth back down on it and forced me to keep sucking on it. She kept saying how horny it’s making her and how hot it looks and to keep sucking on it while she started touching herself and told me to keep doing it until she came! The I noticed his hands grabbed my head and he started fucking my mouth. The head of his cock swelled up rock hard and his cock was raging hard. My girlfriend started touching herself and telling him to fuck my mouth harder! She leaned over and started sucking on my dick and making me hard as my best friend and her are totally getting off on forcing me to suck my best friends cock that is so hard it looks like it’s at least 12″. My girlfriend started to cum and telling him how it’s making her cum until I feel his massive head get even bigger, his balls got really hard and he told her that he was going to cum too! She told me to suck on his cock harder and deeper! He started to cum and shoving it down my throat as far possible when she started to deep throat me and begging me to keep sucking on his dick! She started begging me to keep his cock hard and DON’T LET HIM GO SOFT! I didn’t know what else to do so I started sucking on him how she told me to and he stayed rock hard. She Told me to lay on my back and started to 69 with me. As I’m sucking on her pussy and looking up I see his huge cock start rubbing her pussy lips and his massive head starting to stretch her tiny little pussy lips. She asks me if I can see her pussy lips wrapped around the head of his cock? I told her that I could and she asked me if it looked hot with his huge cock in her tiny little pussy? She knows her tight little pussy lips getting stretched by his massive cock looks super hot and then she asks him “Do you like fucking my tight pussy with your huge cock inches from my boyfreiend’s face?” He must have because he started to cum again and she started deep throating me until I came. She started screaming for me to suck on her clit harder so I could make her cum on his cock.. She would make me do things after that and totally get off on being a dirty little whore. Especially when I would walk in on her being naughty. She’d love getting caught on her knees sucking on a hard cock, the other guy thinking that they just got busted cheating by her boyfriend. Id walk in and the other guy freaking out, and she’d keep sucking on his raging hard on. Getting off on her boyfriend seeing her and just keep going.
