I started lifting her nighty without looking at her but she somehow managed herself and allowed me without saying anything. I lifted her nighty up tha... it was about her panties level. She immediately slides it bit down in shyness. But I told her what are you doing mom. Oil will touch her clothes and it will become unusable and slide it up back again. She was wearing black panty that day and I could see it. I was immediately hard on looking at my mom’s panty. Her full legs were exposed and panty. .. hmmm... don't you big brother? She said as she brought her chest right down onto my face. "Do you want to fuck me?" she asked in a seductive tone while rubbing her boobs side to side along my face. Her tits were so soft against my face and her ass continued to grind on my dick, had I not already blown my load 30 min ago I would have definitely lost it again right now. Trying to hold myself together, dizzyingly and faintly I tried to murmur an answer "no... no I... I don't". "Hmmmm.... So I tried dirty talk. Softer stuff at first, but I was desperate. I wanted to see that look in her eyes that she used to get when she was really coming. I wanted that passion she used to have. I wanted her to beg for it again. I talked about watching her with other men and she even said, "Sloppy seconds" once. I'll admit it. That took me over the edge, but really, only because she was actually participating. See, I was the only one actually doing the dirty talk.I don't know if she let her. Her eyes were rolling back in her head, as I was deep in her. ‘Oh, oh shit! You’re hitting my spot!’ Kimberly announced. It looked like she had a strong feeling to urinate, but instead her pussy squirted a waterfall that lasted about eight seconds. I could not believe how wet she made me, but it turned me on even more. I entered her again and I was pounding away faster and harder. Kimberly was shrieking and pulling me closer to her. ‘I want to be on top.’ Kimberly sighed. ‘No problem, baby.
