Using her mouth, but not saying the words

She gives you a naughty smile "Well he was being so nice and sweet and I really didn't feel like going back to work so I just called in and took the rest of the day off. I then told him I was always curious how he always managed to get so many girls, and immediately his demeanor changed and he got this confident, cocky grin on his face. God it was so hot I felt my pussy start to get wet when he did that." Whoa you were not expecting that, you knew there was a risk of your girlfriend hooking up with other guys but you weren't expecting it to happen so fast and especially with one of your friends. Well you did agree you should keep communicating about what you two do so even though your not sure you want to hear this you put on a brave face. "He just looked me in the eye and said why don't you come over here and I'll show you. I was over there in seconds, so much for not seeming too eager." She lets out a giggle at this as you feign a smile. "So i straddled him and we started making out, his hands were all over god I bet he's been wanting to do that for awhile. So I start grinding on him a bit and start feeling his cock getting hard and oh my god he felt so big. I needed to see it after feeling it for awhile so I asked him to pull it out." As she's telling you this you can feel her rubbing your cock through your pants with her feet, and despite yourself you can't help getting hard. She can feel it too and gives you a wicked smile before continuing her story "So he tells me to get on my knees, I actually almost fell over trying to climb off him. I sat there in front of him just waiting for him to pull that monster out and he tells me to beg for it." Last time you asked your girlfriend to beg for something in the bedroom she got pissed at you, it caused a fight and you slept on the couch. "So what did you do?" "Oh I begged like a slut that hadn't been fucked in months." Your eye's practically bulged out of your head and she could tell exactly what you were thinking. "I need you to respect me as your girlfriend, I'm not going to beg you for anything. He wouldn't respect me either way, and really isn't obligated to." You can't really argue with the logic there but still sucks dealing with it. "So after begging for him to let me see his monster cock he let me pull it out and fuck babe, it was so worth it. That was without a doubt the biggest, fattest cock I've seen. I started pulling down his pants and wow babe even his balls were huge. As soon as his pants were off I was all over that cock. I felt bad I could only get like a quarter of it the way down so I was doing my best with what I could, licking his balls, licking his shaft, dirty talk, at one point I was even rimming him." She has never even offered to rim you "I had no idea you did that." You say exasperated "Well I did it a few times in college but it was never my favorite thing. It was pretty hot with him though with those big balls resting on my forehead and I could hear his sexy moans."
