We are staying at the in-laws house and they went out of town. I was looking for my wife who I didn't know had been napping and reading in her moms bed. I called out for her and she said "I'm in here". When I walked in she was lying on her stomach wearing only a t-shirt and her underwear. I walked in and climbed on top of her and reached under her and started rubbing her pussy while I nibbled on her ears and kissed her neck. After a minute of rubbing/nibbling I rolled her over and tore her panties off and spread her legs so I could lick her swollen clit. She grabbed the sheets and bit her pillow to keep from being loud while I was fingering and licking her pussy. I kept this up until she came and filled my mouth with her wonderful juice. As I swollowed she shoved me on my back and grabbed my cock and before I could say anything had it in her mouth and I could feel the back of her throat. She kept going up and down, I reached up and started rubbing her ass. She felt my hands and moved closer so I could finger her while she sucked me. I gently put a finger in her ass so I was fingering both holes. I could feel her moaning around my cock till she finally turned around and said "I can't take it anymore, put your cock in me now!" I rubbed the head of my cock on her mound and then swiftly inserted my whole cock into her vagina as she let out a loud moan(so much for not being loud). We looked each other in the eyes for a second before we started kissing as I grabbed her hands and held them out. I pinned her down and lifed up and looked her in the face as I pulled almost all the way out and coming back down. I did this slow a few times before I sped it up. She started moving her hips to match my movement. As we lay there fucking each other I could feel her pussy tighten around my cock and she stiffened up as she had her first orgasm that lead right into two more. Then she pushed me back and rolled over stuck her ass in the air and we went right into doggy style almost without missing a beat. I could feel the back wall of her vagina. Everytime I hit it she would squeal a little and I loved it. I kept making her squeal every two/three strokes. She came so hard two or three times and after the last one rolled over and took a breath and said "well, what next?" I knew what was next I rolled her back over and started fucking her in the ass, slow at first then faster and faster as she the extacy of the moment took hold. I pounded her ass till she had yet another orgasm. I could feel my time coming so I started switching from her ass back to her pussy and back a few times. I got to where I couldn't hold it back any longer pulled my cock out rolled her over and stuck it in her pussy and she tightened up as she was cumming again. I looked her in the eyes as I gave her a few more pumps and released my load deep in her pussy. My cock still in her I laid on her shoulder and we held each other for a minute or two. When we finally got up we looked at each other and laughed. I bet thats the best fucking that has ever happened in her parents bed. Now we have to wash the sheets and maybe flip the mattress over. I just hope they go out of town again soon so we can use their bed again.
