My dick accidentally popped out in front of my wife’s little sister [MF]

I have been with my wife since we were kids. She has 2 younger sisters and we have always been close. A while back we were living in an apartment and we went through a period where her youngest sister, who still lived at home was spending a lot of time at our place. She was like 19 at the time, very cute party girl type who loved to drink. She wasn’t getting along with her parents so she crashed with us a lot.
My wife was working nights and I was in between freelance gigs, so me and the sister spent a lot of time together. Not that I was complaining, about the cute young redhead walking around in a towel and hanging her underwear to dry in my bathroom.
She slept on our couch, and wasn’t exactly an early riser. Well one night she mentioned they switched her shift and she had to get up really early for work the next day. I told her I would get her up. My alarm went off at 4. My wife was working overnight so she still wasn’t home. I sleep in my underwear, had she been home I probably would have put on pants to go wake the sister, but it was the middle of the night so I just went in my boxers.
I told the sister it was time to get up, and she didn’t budge. Not exactly surprising. I noticed her blanket was all pulled to the side and she was sleeping in her underwear too. She was wearing a tight little pair white cotton panties that hugged her mound beautifuly with a little pink bow on the waistband just below a small tuft of red pubes poking out. I definitely looked a little longer than I should have, and wound up with a decent halfstack. I realized I should stop staring and get her up. I leaned over, gently shook her shoulder, and again told her to get open. She opened her eyes and mumble something. I couldn’t hear so leaned in closer and said “what?”
Very calmly she said “Your dick’s out” I was tired so it took a second to register and before I fully understood what was happening, she grabbed my semi with 2 fingers. I had forgotten to button my fly and it was just hanging there pretty much right in her face. So she calmly picked it up with those 2 fingers and again said, “dude… Your dick fell out. As she held it it obviously started to get bigger. She gave a little laugh and put it down. “You should probably put it away now.” “Oh shit I’m so sorry I had no idea” “Oh relax I’ve seen a boner before.” “Thanks for getting me up. I’m gonna go get a shower while you take care of that”

My wife gave me a blowjob while I was talking to her sister [MFF]

I have been with my wife since we were kids. So I’m very close to her family. She has 2 younger sisters, and they talk all the time. About everything, I mean like everything. One night they were out drinking together and when I picked her up from the bar she was telling me how her sister’s husband just got into bondage and they spent they tax returns on a crap ton of specialized toys… So yeah they were super open about that kinda stuff.
While we weren’t into bondage, my wife is not without her kinks. She gets off on fooling around in dangerous situation. Like sex in public places and stuff. She loves the thrill of maybe being caught.
Well one day her sister calls up on a video call and she said she had to run to the bathroom and asks if I could grab it. So I’m talking to the sister while we wait for her, when my wife come out of the bathroom signaling that I shouldn’t say anything. She walks over to the chair in front of me and lifts her sundress to show me she isn’t wearing any panties. She sits down, spreads her legs and starts masturbating in front of me. Fingers deep inside while she gets all wet and creamy and tastes herself. All while I’m trying to hold a conversation lol. Her sister was telling me about her recent vacation (I think) while I just gave her a lot of “yeah” “uh huh” “oh wow”. Once I was thoroughly turned on my wife crawled over to the couch and undid my pants and wrapped her lips around my dick. She gave me an incredible blowjob while I poorly tried to pay attention to the conversation. Eventually I finished in my wife’s mouth and had to tell her sister it was a back spasm.
My wife hopped right on the phone to save me, “Sorry I was finishing up the cinnamon rolls for dessert.” Her sister said “Yeah looks like you still got some frosting on your mouth” as my wife wiped the cum off her lip and sucked it off her finger. “Yeah I couldn’t help myself, they are so hot and sticky”
The next time her sister was over our place my wife couldn’t help herself and told her what happened. “Ohhhh well that explains it hahaha you weren’t bored that was just your O Face hahahaha. ”

I tricked my sister in law [F] into looking at old photos of me fucking her sister [MF]

Years back my wife’s little sister was visiting us from out of state. It was cool because we had been together since we were kids, I had even briefly dated her sister before I got together with my wife in like 9th grade. Nothing serious, but obviously we were all close. She was cute, and we probably flirted a little more than we should have, but no one ever took it too far or got upset, it was all harmless fun.
But all that flirting was definitely a turn on. I wasn’t about to start anything up but I did really enjoy the attention and the sexual tension. With that in mind, I came up with a way to excentuate that while getting to show off a little as well.
Back in highschool, I had gotten to take a photography class, which was nice because it gave me the chance to develop my own film. Back in the day before cellphones this was the only safe way to take nudes, especially in highschool. I had quite the collection ranging from classy artsy stuff, to spread eagle, and crummy blowjobs. My girl had taken some very flattering closeups my dick at the time as well. I have a small box of some of my favorites I keep handy for jerking off with.
My plan was fairly simple. I took this box, and I moved it to the cabinet under the sink in my guest bathroom. Next I would stage the toilet paper to be on it’s last square just as her sister was about to go in. She would ask through the door if I had anymore. I would tell her to check under the sink. I had indeed put a roll under there, but I had also had the box of photos placed precariously behind it. Removing the roll insured the box would fall out, spilling the photos all over the floor. So now, she is in a locked room, with her phone, and a whole box of amateur porn of me and her sister. I have even subtly placed a hair on the lid of the box, that would tell me for sure if the hair had fallen off, the box had been opened.
Well I set everything up and even though she seemed to be feeling fine just before, the little sister would up spending a full 30 mins in the bathroom that night…. I later checked, and not only was the hair gone, the photos were all out of order. I absolutely LOVE knowing that she was going through all the photos. I wonder if she just looked at the naked pics of me, or she was looking at her sister as well. I wonder if she got turned on seing my cum in her sister.
