6 months ago I posted here about how my girlfriend (Sam) taught her sister (Annie) how to suck dick by practicing on mine.
Well its been almost half a year now and Annie has gotten better. A lot better. In fact, she’s starting to ask to do them now more out of enjoyment than actual practice. Sam has always been supportive seeing how she loves her sister dearly and has complete trust in me, and since this has been a regular thing for a while, I have gotten quite used to it as well.
I guess it was only a matter of time before this happened.
During one super hot Saturday, I visited her home again for our usual weekly date. Brought with me a box of doughnuts and some roasted chicken for the pair (they really love roasted chicken). Their dad had already left for his job earlier in the day so it was just us three chilling on the ground floor. Annie was busy watching Loki while Sam was cooking some tuna alfredo in the kitchen. Due to the heat, and how comfortable they are towards their own skin, both of them were wearing thin tank tops and beach shorts with no underwear beneath. I greeted them both and soon we were gathered around the dining table eating lunch and talking about our weeks. Didn’t really remember much of it since itwas pretty normal.
Once we’re done though, I volunteered to clean the plates. The girls agreed and they cleaned up the table and put the leftovers away. All was pretty normal until I felt a hand reach inside my shorts and hold my butt.
“Are you going to do something with sis?” It was Annie, her voice hinting that she wants to do something.
“Probably. Want to practice?” I said.
“I watched a how-to video. I was thinking I could try.”
“That video?” Sam laughed as she put away the last of the chicken. “Just say you want to suck his dick. I can teach you better things than that video.”
It was then I started to get a bit of an erection. Not a full blown one but enough to start popping from my shorts. Annie moved her hand to the front and started fondling with my trimmed pubes. “Can I?”
“Now?”
“After brushing of course.”
“How about a better idea?” Sam grinned as she approached us. “Annie, brush your teeth. And you… mind meeting us in my room in a few minutes?”
“What do you have in mind?” I asked, already curious what thoughts she had in her head.
“You’ll see.”
“Shower?”
“Sure.”
And so I did. Whenever Sam had these ideas that made her grin like that, I knew it would be something special. “Experiments” she called them, but it was more like a very tiring session. After cleaning myself up from my travel and making sure I was hygienic enough for them to do whatever they wanted, I went into her room wearing only a towel. There, both of them were talking with excitedexpressions.
“Ah, you’re here. Can you lay down?” Asked Sam while she grabbed a box of bondage gear.
I did as she said before I was laying there naked with my wrists tied to the bedposts and my ankles tied together. The restrains on my ankles were different than just standard straps. It was one long strap with each end fastened on an ankle. From that alone, it wasn’t much of bondage but the strap went under and around the mattress. That made it very much a bondage tool, and it was one I had used only twice before.
Both girls then undressed. Both are as beautiful and as eye-stimuating as always. A-cup breasts, erect nipples, and trimmed pubes that I would’ve loved to run my finger through. Just the sight of them made my dick hard.
“How good is Annie now?” Sam asked.
“Pretty good. She can make me cum a lot faster now.”
“Okay, here’s what’s about to happen.” Sam sat beside me and softly stroked my dick. “You are going to be the judge in a blowjob contest.”
“Uhh, okay.” I said, thinking about what’s gonna happen in a few seconds. “You’re cheating right now.”
She stopped. “We’ll get 30 seconds to suck you off before switching. The one to make you cum wins.”
“You’ll be blindfolded, of course.” Said Annie, twirling a black blindfold on her index finger. “Don’t want you to cheat and pick the winner.”
“So I just cum? Hold until I can’t anymore?”
“Exactly.” Said Sam. “But some rules for you. You can’t say when you’re gonna cum. You can’t ask for the timer, and you can’t speak. Moaning is fine but no speaking and the most you’re gonna hear is the timer finishing. Also, no touching.”
Hoo boy, this is gonna be interesting. “Alright.” I looked at Annie. “Are you sure about this? This is your sis you’re fighting.”
“It’s just for fun.” She smiled, eager to start. “I’ll put the blindfold now.”
And just like that, I was in the dark. I heard footsteps as one of them went to the other side of the bed, a period of silence, and a piece of metal hit the floor. It was probably a coin, I guessed, so they’d see who goes first. And sure enough, I heard the bed creak as someone got on it between my legs. I felt a hand touch my shaft… and then the contest started.
I couldn’t tell with absolute certainty who this was. My head was being toyed with her tongue, moving it in a circular motion that stimulated my entire head. Then came the suction, the bobbing of my dick in her mouth. She’s good, I’ll admit, but it could easily be either of them. Then I heard the timer’s beep, signaling the 30 seconds had ended. The force on my dick left and then quickly came the next one.
This one certainly took advantage of the first one’s work. I was already very hard and this one seemed to know that and build her way around it. I felt the walls of her mouth wrap my dick in suction as the tongue stimulated my head, and I felt no teeth. Whoever this was, she knew what she was doing. Is this Sam?
The timer beeped and the next one started. While I felt the full force of the blowjob, this one played with my balls too. Gently playing with them as it accompanied her talented mouth. Still, I felt this one was Annie. It certainly felt a lot more amateur when compared to the one before. Good, but still a level or two below the last.
The timer beeped and the next one started. By now, I knew I wasn’t going to last my usual. Whenever we did anything sexual, regardless if it was any type of sex with Sam or a blowjob from Annie, both took the time to slow down when I was starting to show signs that I was getting close. It made for a longer, more thorough experience and bigger cumshots, something both really really loved (and to be fair I do to). A “quick” session would generally take anywhere from 15-30 minutes. This though, I can tell both are trying to make me cum as soon as possible.
I started moving my hips as a result. Nothing in the rules stated I can’t start moving when close after all, just not to tell them when I’m about to cum. Whoever was sucking me then started upping her effort. This has to be Sam. It has to be.
Timer beeped, the next one started. She continued the amazing feeling that made my toes start curling. I started holding on to the bedposts, feeling I was already close. Not quite there yet, but close. One of the girls laughed as I did so but I couldn’t figure out who it was since I was using all my concentration to hold from cumming.
Timer beeped. Now I was definitely starting to getting close. My body became stiff as stone, trying to push aside the bubbling feeling in my balls. The tip of my dick was already super sensitive, able to feel every single millimeter of movement of the tongue caressing the skin. I tried closing my legs by the strap didn’t allow it.
Timer beeped. Didn’t know when it was but I edged. The one sucking hit a weakspot of mine that almost made me cum but I somehow managed to hold it in. If she had focused on it just a second or two more, I definitely would’ve popped inside her mouth. If it wasn’t clear yet I was near, it definitely is now.
Timer beeped. The half-second that took to switch did absolutely nothing. I held on for maybe just three seconds more but this was my limit. I came hard, 3 days worth of cum spewing into someone’s mouth. It felt amazing… I wonder who the winner was?
The winner let my dick and my load soak in her mouth for a while before spitting them out. “Hold his legs!”
As the loser held on to my ankles, the winner put my dick back in her mouth and started sucking hard. Harder than what either had done today. My dick, covered with my cum and her saliva, became super slippery. And having just came, it was too much.
“Please!” I cried out but she continued sucking as if nothing happened. It felt overwhelming, but even more so when she targeted my weakspots. And did she target them really well. This is Sam. No doubt about it. No one else knows me as well as she does. And being Sam, she bided her time with each one, making sure to completely exhaust each one before moving to another. Pleading didn’t help. Hell, she loved it when I did that out of desperation.
Timer beeped. The 30 seconds ended but she didn’t. My now I could feel her nipples on my torso. She must’ve moved to a 69 position but her legs are nowhere near my head.
“Annie!”
The moment she called her over, I felt two tongues wrap my head. It felt fantastic, euphoric, but over-stimulating. Both girls were obviously having the time of their lives there are my cock pleaded with me to stop it. Not that I can actually do anything though.
As someone who has experienced post-orgasm torture before, the entire experience feels unusual. Part of my body wants to push them away and let my dick recover but there is undoubtedly pleasure beneath it. Their tongues felt 10x stronger than before, and the other part of my body that loves it wants it to continue. Fortunately, it wasn’t up to me.
“Can I do it, sis?”
Annie soloed my dick, making my body move on instinct. Sam, seeing the opportunity, kissed me. Her tongue went into my mouth and I can distinctly taste my own semen in there (it was a bit salty). I was getting stimulated in the two most sensitive areas in my body simultaneously… and the two sisters were loving every second of it.
My dick started to get hard again. Even after cumming just now, it felt like it was almost ready for another. Annie probably knew too, feeling her increasing the suction as I got harder inside her. Sam stopped kissing me and decided to sit on my face. With her lips on mine, it was a signal it was my turn to start giving. And so I did as I got ever harder.
It would probably be best if I gave a signal, told Annie I was about to cum since I was about to. But it felt fair that she gets no heads-up too. I felt her mouth wrap my most sensitive area more… and more… and more…
I spewed my second load inside, hoping to catch her by surprise when in reality she seemed to have expected it. It was a lot less than before but she didn’t care. She let my cum, and my dick for that matter, stay in her mouth for a while before spitting. Good thing she stopped too because I felt my dick start getting soft.
Sam lifted my blindfold and kissed me again. “I won.”
“I know.” I looked at Annie who was playing with my soft dick and my cum that has gathered on my pubes. “Had fun?”
“Of course!” She winked. “Tell me honestly. How good am I now?”
“Uhh from a rating of 1-10? Around 8.”
“Want to practice some more?” Sam asked as she untied my left wrist, to which I immediately started feeling her smooth body. “I’ll be happy to help you get to a 10.”
“Let me get some rest first. And a doughnut.” I said, sitting upright after getting my second wrist free.
An interesting experience indeed.

Oh… sorry but I forgot to remove the “[Part 1]”. I initally wrote this to be 2 parts but then decided to combine it into one. That was my oversight.
