Caught

I was jerking off the other day while house sitting a sister in laws place. I was in the hot tub with a few beers waiting for my wife to show up so i took my shorts off and started stroking myself. Little did I know that her daughter (17) at the time saw me through the kitchen window and was in shock but I didn't know that at the time. Well i guess she told my wife when she got there and later on while in the hot tub with my wife she brought it up saying " hey you know Sydney saw your jerking off in the hot tub eh" and I was like I have no idea what your talking about and my wife looked at me like?? You think she would make that shit up? She told me when I got here, she said your pa to were and your stroking yourself. Man was I embarrassed as hell not only for me but Sydney too. I told my wife that I was going to go apologize to her but she said she had already left. I couldn't believe it. Super embarrassed and thinking my wife hates me or is judging me huge i get and grab a couple more beers come back and now my wife is naked in the hot tub, I'm like what the fuck is going on as she laughs. She tells me to take them off again and get in, I'm like what if she fucking comes back, don't worry about Sydney she says she got a dick to suck tonight(her boyfriends). So I get naked and hop in, we're making out feeling and fingering. She tells me to lay back on the tub and slowly licks my inner thigh, next my balls then starts sucking. She take my cock out of her mouth and tells me "i think its fucking hot you got caught" i was like really? I thought you would be fucking pissed, nope made me super horney for sure. She hopped up bent over the edge of the hot tub and told me I could have whatever I wanted. In my head I was like wow this is nuts but I'm going get what I want. I firmly push my face and mouth into her pussy and locked and ate for a while, she moans what about my ass you want that too? Fuck yes I said, I started licking her asshole while I had a couple fingers in her pussy and she was super enjoying it. I tried to put my dick in her ass but she was too tight and didn't want to force it and ruin the experience we had going, I tried a couple more times and she told me to spit on i said you suck it sloppy and ill spit which she did. I tried again but just couldn't get it in. I threw it in her pussy instead and we fucked for a good while. Finally she told me tonstop and said she wanted my cum, so she went back to sucking my dick until I gave her a nice sloppy facial in the hot tub. All she said after that was we need a hot tub at home.
