What triggered it all was Sophitia from Soul Blade, ad her all-time popular move "widow-maker". When I first found out about the move (I was a 10 or so) I found that using the move against the girls...is a lot of fun! From then on, I secretly indulged myself at every 3D-fighting games I found (which was the SOLE reason of my buying any 3D-fighting games at all). Seeing the girls writhe and moan in pain all the while holding their crotch is a scene so erotic I fapped while doing said moves over and over again. I mean, come-on, you must've also thought of this, right? Let me give you some examples that I considers the most...yeah: 1. Aside from Sophitia's widow maker, I find that Kilik's Dirty Bo (or Mina's Opening Treasure) as even more enjoyable. Imagine you are a girl and your feet rendered helpless with you, barely standing with your nether-region wide-open and close to ground, and Kilik's Bo is just below ready for some leverage. What happens next is for you to imagine. 2. In Rival School, the team attack that occurs when you're partnered with Skull AKIRA, called Gang Bang err, Gang Buster was so very enjoyable. You hold the poor girl in place while AKIRA hit and kick our victim helpless. As a finisher both you and AKIRA strikes at the girl's nether region, simultaneously from opposite sides. By the way, AKIRA's a girl. 3. All Hail King from Tekken. His Manhattan Drop and Head Bomb are the only reason for his existence. Head Bomb looks like he's ready to cunni the girl but drops his head with a crushing force instead, you know where. Manhattan Drop is Atomic Drop on the wrong side of impact. 4. Don't forget Busuzima from Bloody Roar. His throw move looks like the ass-spanking you do to brats, but he hits them at the opposite side of the ass instead. After I was introduced to Japanese Culture, I eventually learned of what's called denki-anma (literally close to electric-vibration). Denki-anma is an act of tickling your opponents nether-region with your foot, or heel. However, due to the erotic nature of it, it's often employed during a sexual play. And sometimes, the tickling might even be replaced with violent stomping or kicking for much desirable effect. Oh, and don't forget the wooden-horse. While maybe not using the literal wooden-horse, but this act defines sticking one's nether region to a blunt surface all the while being bondaged or suspended to let gravity do the job. Very erotic. YOUR contribution is greatly appreciated by providing more examples or any material containing this. Adieu for now.
