[Going to the adult shop with my sister...] Blow job training in the car with a dildo I bought~Has she improved?! She can't help but cum in my mouth during the practical training‼︎~ [Introduction] *Must read, especially for first-time viewers. This is the latest in a series of works about P-activity with my niece and sister. The filming period is the most recent data. This is a practice + practical training video for my niece and sister who has little experience giving blowjobs in private and is not good at it (she's bad at it). As a result, her technique is also amateurish, so please be careful if you are looking for a highly erotic blowjob video with slurping sounds like an AV actress. The sister is in a business suit from start to finish and doesn't take it off, and after the everyday scenes, she practices blowjobs and gives a practical training video with great effort. If you understand the older sister's personality, you will enjoy the story of how the older sister, who is not used to it, tries harder than ever to overcome her weakness in blowjobs, and how her blowjob technique gradually improves and becomes more pleasurable. I'm sorry I'm so bad... I'm gross, but I want to get better... but I'm still gross... and her feelings and the changes from before. [Main content] *Please take a look at the first 30 seconds for a brief announcement about the release of future works. Unfortunately, it was raining heavily that day... My older sister, who was on her way home from job hunting, is stupid so she didn't have an umbrella, so I, the uncle, decided to pick her up in the car. When we met up in the car, she said she wanted to go to a slightly larger used bookstore nearby because there was a manga she wanted. We had a little conversation in the car as we headed. When we arrived at the store, it was a weekday before evening, so the store was relatively empty. In addition to used books, this store also had many used items such as figures and games. My sister immediately headed for the manga section she was looking for, but I, my uncle, found a certain section further back. There was a curtain that said 18+, so it was probably adult DVDs or adult goods... My sister and I looked around the manga and figure sections, and managed to get an upside-down shot of a panty shot on my iPhone. After that, we casually wandered around the store and ended up in the 18+ section. My sister somehow ended up following my uncle and going in... What is this place!???? She was a little grossed out, but it was her first time in a place like this, and despite her grossed out words, you could see her eyes looking around with interest. Although she does seem to be a little condescending towards her uncle (a perverted man), when he suggests a dildo, saying that it could be used to earn her some pocket money, she is quite disgusted, but ultimately says that she can just buy it herself... Of course, my uncle intends to buy it himself, but that alone is not interesting, so he has my sister hold the dildo and pay for it. The cash register is like the reception desk of a love hotel, with a small window so you can't see the clerk, but it's strange to see my sister in a business suit buying a dildo in the middle of the day. Of course, the clerk is a man. The reaction of my embarrassed sister is also worth watching. I handed my sister a 10,000 yen bill and had her pay for it. The change was an embarrassment fee, so she put it in the pocket of her business suit... When we returned to the parking lot where we had parked the car, my uncle looked at the dildo I had bought and asked me if I wanted to try it today to earn some pocket money, but I said no, gross! It's my period! says my older sister. But what if it wasn't my period?! But my uncle wanted to use it as soon as he bought it... Let's practice giving blowjobs with this! I suggested. I didn't actually have to suck my uncle's dick, so it's perfect for practicing! I suggested it to him, and he reluctantly agreed, saying that it was only with pocket money... After that, we moved to the back seat and started practicing giving blowjobs with the unpacked dildo. Just as my older sister started to suck the dildo, someone got out of the car parked next to us and looked in through the front door, which had no tinted windows... Although no one had taken off their clothes, we were witnessed in broad daylight in business suits with a dildo in their mouths, so we hurriedly moved the car. We moved the car to an empty space on the roof and resumed practicing in the back seat. The dildo was the type that stuck with a suction cup, so we stuck it to the car window and had her practice giving blowjobs. At first, my sister was disgusted, but maybe it was because it wasn't my uncle's thing, or maybe she was aware that she wasn't good at giving blowjobs and wanted to improve a little... She wasn't particularly into it, but I could tell she was trying harder than usual. (Just like a niece and her sister trying harder.) However, my uncle was watching her practice, and although it was erotic to see my sister sucking the dildo, it didn't make my uncle feel good at all... Anyway, he praised my sister, saying, "That's right! You're getting good!" and suggested that they practice. She was reluctant, but agreed as long as she was given some pocket money. My uncle immediately took off his pants and asked my sister to do it just like she had practiced. Her blowjob was still as awkward as ever, and I had only taught her the most basic of things, but it felt much better than before. And the biggest difference from before is how hard my sister is trying. Maybe because I praised her for getting better, I could tell she was taking it more seriously than usual. (If it's your first time seeing her, you might think she's being serious about this!?) Technique-wise she still has a long way to go, but when I give her instructions like licking the balls...sucking...rolling...touching the balls...touching the nipples...going as deep as possible...using her hands a little faster...she does her best in her own way. She's not very good at deep penetration, so sometimes she chokes, but even if I stop, she keeps trying hard and keeps going. She's not super good at it, but she's grown to the point where she can get off just from my movements, so my uncle, who is getting more and more aroused... I tell her to stroke faster, and finally I cum in her mouth while holding her head down! Surprised by the force of the sperm that came out, my sister immediately opens her mouth with a look of disgust on her face, and the sperm overflows from her mouth. It wasn't a huge amount, but you can see that it came out with quite a lot of force by the pulsating movement of my uncle's dick while he was ejaculating! At the end, my sister spits the cum left in her mouth into a tissue and wipes it up. This is how the video goes, and in the car scene in the second half, it's just a blowjob, but as an uncle, I could sense a slight change in my sister's attitude towards blowjobs. Of course she feels disgust, but more than that, she feels sorry, wants to improve, is confused by the unfamiliar movements... and is embarrassed because she's being filmed... It felt like a blowjob lesson full of a mixture of emotions from my sister. Her confused but interested reaction at her first visit to the adult shop is also worth watching. I don't know if my sister's blowjob skills will improve in the future, but she's bought a dildo so I'll have to think of a way to use it.
