I didn't mind the break in her play on me because to be honest I was ready myself to enjoy her. I kissed her for a long while and then squeezed one of her full round breasts. She moaned and I knew she was in favor of us continuing. I reached down and undid her shorts and unzipped the fly. I told her to sit on the couch and I pulled off her shorts but left her black panties on. They were visibly moist where it counts. I leaned in between her thick legs and spreading them apart with my hands I planted a soft kiss right on top of them in the middle of her wetness. She moaned and I looked up and told her to be quiet with my finger. She giggled and covered her mouth and I then pulled her panties out of the way and took a proper taste of my mother-in-law. Her pussy was so wet and ready that it was a real shock. She must have been getting very worked up from all that she had already done to me. I knelt there on my floor with my face buried in my mother-in-law's wet pussy and ate it for what it was worth. I slid one, and then two, and then three fingers inside while I sucked and licked at her clit. She was getting really worked up, her breathing was getting quite intense. At one point I looked up at her and she had her eyes closed, her hands were squeezing her own breasts. I pulled her shirt and her bra down under them and squeezed them with her.
I was at a crossroads at this point of course. I really wanted to make her cum but I also really wanted to fuck my mother-in-law senseless. I was pretty sure my father-in-law was snipped to be baby free after their 4th daughter so I was thinking her pussy was going to be off limits unless I sneaked upstairs to grab a condom. I wasn't sure if that would spoil the mood for her if I left her alone. I stopped eating her pussy and looked her in the eye and asked if she wanted me inside of her. Just like her daughter she replied with a big "yes!!!". I told her the problem how I wasn't sure if she wanted me to leave her to get a condom. She told me we wouldn't be needing one. She told me to lie on my back and she took off all of her clothes while she helped me out of mine. I was naked on my family room floor while my mother-in-law mounted onto me. Her big sagging breasts hung down so far I could practically latch on without moving my head up too far. I sucked on each nipple while she ever so carefully lowered down onto me. I slid in very easily despite that I realized I was probably the biggest guy she'd ever had. Her pussy was so wet and it felt so good to slowly stretch her while she rode me. Her nipples were so hard I could tell she was having the time of her life. I was a little worried about starting to cum before she had used me for her pleasure but decided I'd tell her when I was close in case she wanted off.
It turns out she wanted off sooner than me. After maybe 2 minutes she pulled up and off of me and gave me a deep kiss telling me I had just made her cum...she was really quiet about it so I was surprised to hear it. She told me she wanted to keep going until I came and then proceeded to ease back onto me after a little more kissing. This time it was much harder to enter her. I think she was more like my wife than maybe I would have wanted. My wife doesn't like to have sex too soon after an orgasm, her body just isn't ready for it. Slowly though she kept on going and soon we were back to having her riding me up and down. She felt so tight and I felt so turned on by my mother-in-law riding me with my hands guiding her hips up and down, up and down. Soon I knew I was going to cum. I told my mother-in-law and started to guide her up off of me. I had no intention of fathering my next brother- or sister-in law!!! She pulled my hand away and said it was ok, and to just keep going. I figured she probably had some condition where she couldn't have kids again and just let myself go. I fucked my mother-in-law quite hard at that point, guiding her up and down and letting her slam down onto me while I filled her full. I started to cum and I felt this wave of pure pleasure pass over and through me a moment before I felt my balls release their hot white milk inside of her. She rode me much gentler for a while until I became soft and she finally took me from inside of her. She leaned down and kissed me again and then asked if I wanted to try something really wild with her.
At that point, I had already not only kissed my mother-in-law, I had received an amazing blowjob from her, eaten her out, fingered her, made her cum by fucking her and then have her make me cum by fucking me! I wasn't sure what she had in mind and I asked. She told me to sit still and then she slid up my body. She got up on her knees somewhat and moved closer to my face. She looked down at me and said she would really love it if I licked it out from her. I suddenly realized that my mother-in-law was a much dirtier woman than I'd ever realized. I managed a pretty feeble "ok" and she straddled my face and I started to lick. I could actually taste my cock on her pussy, and she was really wet but I could not taste my cum. I must have shot it really deep inside of her. I continued licking her waiting somewhat anxiously for my hot white reward. Finally she sort of eased up somewhat from my face and laughed somewhat. She had a bemused look on her face. I was worried that maybe she knew I had already masturbated that day and there maybe wasn't much that I had actually pumped into her.
She told me it felt really nice the way she was licking me but I had the wrong hole entirely. Oh My God! I had cum inside her ass! She moved back down onto me and I realized why she had been leaning back so far while she was on top of me. Her ass was much easier to reach with my tongue and sure enough I could taste the flavor of my cock on her and then suddenly I tasted myself on her, my own cum started to drizzle out. I ate all of it and continued to lick her ass until I started to get hard again. She reached back and played with me while I did something I'd never even dreamed of doing in my life. After I had all of it out of her, she climbed off of me and went down on hands and knees and told me she was ready for more. I fucked my mother-in-law in the ass harder than I had ever done with anyone else. It was so freeing and by the time I came she had already cum from touching herself with her hand. I pulled out licked her ass a final time, we got dressed and we've kept our secret ever since.
