Birthday Weekend Celebration With Nephew

We landed late the first night so hung out at the hotel and just partied at the bar.  The next morning we ventured out and being in Colorado we grabbed a weed vape and began our weekend off fun.  We partied late that night and crashed once we got back.  The next morning,  the nephew, being a college kid, was passed out. My wife whispers to me, "Let's go shower."  Typically we don't fool around if we have company over, wife's rule.  I was excited about the offer.  We headed to the bathroom and before hopping in, of course we took a hit on the vape.  

We hopped in the shower and started making out.  I was totally turned on, just the thought of my wife wanting to do this with her nephew asleep in the room next to us.  Knowing we weren't spending a ton of time in the room we booked a single room, 2 queen beds and shower.  My wife only cums from clit play, so I kneeled down in the shower and she bent over.  I teased her lips and ass a little before starting to lick her clit.  As I was licking her clit. I couldn't help but jerk my throbbing hard cock.  I'm not sure if it was either the weed high or nerves of the nephew in the next room, but my wife was close pretty fast.  Once I could tell she was close I stopped stroking my cock and spread her ass open for a better angle.  She just kept breathing heavier and quietly moaning with the build up.  I could tell by her asshole puckering, she was close and I whispered cum for me baby.  Just then,  she let out a louder moan and thrusted her ass against my tongue as she cummed.  After she finished, I said to her, "You were kinda loud." She said, "He's a heavy sleeper we're good."  That turned me on even more. 

She then said to me, "You already look turned on. Do you want a blowjob or do you want to fuck me?"  She didn't talk like that ever,  so I took the fuck. She bent over in front of me and I slowly slid into her soaking wet pussy. She has always been really tight so I have to start off slowly. As she got used to me, I was able to pound harder. With the high going, it felt more amazing than normal.  My wife is a bbw with a big ass and huge breasts.  As I began pounding harder,  I could hear her breasts clapping in the water.  Again, my wife, typically shy and quiet was moaning with every thrust.  After fucking for maybe 5 minutes,  I could see light from the bathroom going into the room.  I found it odd. I thought we locked the door.  The shower curtain was white cloth, but had see through areas near the top.  I'm tall so while thrusting I peaked over and saw her nephew in the doorway,  his shorts on the ground and his dick in his hand.  He was standing there jerking off to his aunt moaning and getting fucked. This turned me on as well, knowing he was there. We have talked before and he had joked in the past about the size of his aunt's tits. He never asked, but I was young too at one point. I knew he wondered what his aunt's tits looked like.  After a couple of minutes I looked again and he was still going.

I got my wife's attention, and mouthed to her, "Your nephew is jerking off at the door."  I honestly thought we were fine and she would say something over the curtain to go away.  She looked at me and whispered, so you want to stop.  I said no,  I'm getting close.  She said nothing back, just bent over and spread her ass. I didn't even know who she was at this point. I slowly slid back in her wet pussy and started pounding again.  A couple of minutes later as I was pounding ass, she looked back and mouthed to me, "Is he still there?" I peeked over, and of course he was still there, jerking his cock.  I shook my head yes, and gave her the jerkoff signal with my hand. She smiled at me and mouthed back to me are you close? I nod yes but continued pounding her ass. My wife, then in her normal speaking, voice no longer a whisper moaned out, "Fuck me hard baby."  I couldn't even believe this. Not only was she still wanting to have sex, knowing he was there,  but she was basically putting on a show... 

I couldn't believe what happened next.  As I was thrusting hard against her ass, her breasts smacking back and forth in the water, she was moaning now loudly with every penetration. She grabbed the shower curtain next to her and peaked out. She stopped moaning and she looked.  I couldn't even believe she was doing this. Within minutes of doing this,  she grabbed the curtain and swung it back, opening the curtain almost fully,  exposing her naked wet body bent over in front of him,  mine too technically. Her nephew stopped immediately, jaw dropped to the floor,  cock in hand.  I stopped also while deep inside her.  She said without missing a beat, I don't know why either of you stopped. I wasn't going to miss this opportunity so I began pounding again. Her breasts started bouncing back and forth again.  Her nephew just stood there,  staring at her.  My wife then said, "You were spying and turned on by this.  You'd better take advantage of this. It won't happen again." At that moment he began jerking his cock again. 

I noticed at this point as I fucked my wife,  she kept looking his way,  watching him jerk his cock.  It didn't take me long after and it was really close.  I said out loud,  "I'm close baby."  I was thinking she would just thrust up against me and have me cum inside her.  Again she threw a curve ball. She climbed off my cock and turned quickly on her knees in front of me.  Huge tits with skin-colored areolas and her hard nipples on display. She grabbed my cock in her hand and started jerking it as she took my cock into her mouth.  She pounded my cock in her mouth maybe 5 times and I exploded. First load into her mouth, the rest she pulled off and jerked onto her breasts and face. Just as I finished cumming on her breasts, her nephew let out a moan and shot his load all over the ceramic tile floor.  My wife watched as he came and finished. She looked at him and said, "Good boy."  Then she stood up and said to him,  "Please wipe up your cum. We're going to clean off, then you can shower."  She shut the curtain. 

I said nothing, just cleaned up.  We dried off and went into the room, and her nephew went in to shower.  I asked her where this all came from. She said I think the vape made me really horny and took away my fears of others.  She then said she was going to talk to him about not telling anybody about this.  I agreed. She got up and walked back to the bathroom towel wrapped around her and opened the bathroom door and walked in.  I could hear her saying something.  She was in there for a bit then walked out of the bathroom with no towel on.  I said to her,  where's your towel?  

She said she walked in and the shower curtain was half open and he was jerking off. She said, "Hey, I thought you already did that."  He responded that he couldn't stop thinking about her breasts and got hard again.  I guess she dropped her towel and he jerked off looking at her nude and came again. She said they would talk later about not telling anybody. 

Funnily enough, later on he and I were drinking at the bar and he brought it up while she was in the bathroom. He said I couldn't believe Aunty did that,  I laughed and said me neither.  He then said that when she came back in and caught him jerking, she dropped her towel and said, "Oh sorry."  He said to her he didn't mind.  But what my wife didn't tell me was,  he said, "I love your huge breasts."  My wife smiled and saidt hey are nice but that I liked her ass more.   She then turned around and bent over,  revealing her asshole and pussy in doggy view. Her nephew said she looked back and smiled. As she did that, he came again in the shower.  He said to me he had no clue Aunty was a freak and that I was a lucky man.  I laughed and said typically she's not.  

Nobody has talked about that day since. We partied the next 2 days before returning home.  I can't imagine being him and having my aunt do that with me.
