So this one is probably not going to do it for most here, but this little 7 minute video from 10+ years ago is easily my go-to when I'm being efficient. It's so simple, I imagine it won't seem the least bit special to anyone else. I don't know who this Vanessa woman is. I've found at most 3 videos of her that she may have done for abbeywinters.com and nothing else. And for the life of me, I don't know what it is about her that gets me going, but she fucking does it. I find her hot as fuck, yes, but it's not like she has any obviously stunning features. She seems like a normal person.
There's just something about the self-shot, low res camera, her Australian accent, the context of her getting home from a rough day and just wanting to cum and relax. I'm not usually one for too much talking, but I love the way she guides the viewer through her routine, what gets her off, and ultimately letting us know when she's about to cum. The confidence she gives off makes me melt and I always watch the whole thing, finishing right when she does. It's perfect.
There's this Blender/SFM video by the artist Evilbanana with an anthro, male-appearing Eevee alone in the woods, riding one of their favorite toys. But when they cum for the first time, they begin to evolve into a Leafeon and now their body is a lot more shapely and feminine - but still they have their dick and it's even a bit bigger. So they keep enjoying themself, exploring their new body, and eventually cum again.
There's a scene in Teagan Vs. Jenna (2009) called Jenna and Scott. Scott Nails fucks Jenna Haze doggy style and the way she moves her hips and backs up against him just does it for me.
