Vacation Surprise

My wife and I go on vacation with her parents every year to a beach house on the gulf. We've all been going for the last 10 since we were dating.

One morning I woke up not feeling great. We sat at the breakfast table as they made plans to go to another beach about 20 minutes up the coast. I told them I'm not feeling great, I'm just going to hang back. My wife wasn't concerned. She just said ok, she was going to go. I said that's cool. Her mom, dad and herself got in the car and left. I really just wanted time to myself. I went into the bathroom and saw my mother in-laws panties on the floor. I picked them up and sniffed them. When my nose touched them, they were a little moist. I went into the bedroom. I put in my earbuds. I listened to some tunes as I sniffed her panties and jerked off. I was really getting into it. Pouring oil on my cock and balls.

Now I never heard my mother-in-law get dropped back off. She told them she felt a little dizzy from her vertigo. They dropped her off and my wife and her Dad went to the beach.

I'm jerking off, edging myself. My mother-in-law could see me through the crack of the door. I had her panties in my mouth as I continued to edge myself. As I relaxed myself not to cum yet, I opened my eyes and saw her looking in. When we made eye contact she pushed the door open. I started to stammer and stutter to explain. She put her finger to my lips and said Shhh. She shoved her panties back into my mouth. She took my semi erect cock in her hand and started to stroke me, and rubbing my sack. She then stripped off her bathing suit and was standing there naked. She has such a hot, thick, milf body! Small waist, thick ass, and perky c cups. She pulled her panties out of my mouth and sat on my face. I smelled the familiar smell from her panties. Once my tongue slid in it was so delicious! She let out this ungodly moan and then took my cock in her mouth. We 69ed for ever. It was so incredible. She fingered my ass and rubbed my prostate as she slowly sucked me. My face was soaked from my spit and her juices. She started to speed up. I could tell she was going to cum. She came and squirted on my face and in my mouth! I continued to lick and suck as I exploded into her mouth. She swallowed all of me! Once she was done. She turned around and laid next to my. She kissed me! It was the sexiest fucking kiss. Very soft, with a little cum left in her mouth. We made out and kissed until I got hard again.

She got up and went on all fours on the bed. I went to stick it in her pussy. She stopped me and guided me into her ass. Fuck my fat ass she commanded. She didn't need to tell me twice. I began slamming my cock into her bowels. I could feel her rubbing her clit when my balls slapped her pussy! I was ready to cum! I told her I was going to blow. Cum in my ass! She screamed! I let loose and exploded inside her fucking asshole! I pulled out and as my cum dripped down her pussy she caught it with her hand and continued to rub it into her pussy! She furiously fucked herself until she came. She collapsed into a sweaty heap on the bed. I took her into my arms as we kissed. She told me we shouldn't have done this but it was so amazing! I said the same thing. We continued to kiss. I then let her get up. She put her bathing suit back on and took her panties. She then said that hopefully we can make this work because I don't want it to end. She kissed me again.

I thought about the sex and it was a million times better than her daughter. Sad but true. I'm never going to be able to give this up!

I then just collapsed and fell asleep.
