Regarding beagles, somewhere else on the forum a member said that they are well endowed for their body size. Then, some time in the last 2 years I saw a homemade vid with a woman in her bedroom getting mounted by a smallish dog that looked a bit beagle-like. His hair might have been a bit longer, but his coloring and size were like a beagle. It wasn't a high res vid. It was filmed from across the room, like as if she'd set up her phone on something way back away from herself.
If anyone is trying to figure out this vid, she seemed to be over 40 years of age. She and her dog were definitely not newbies. He knew exactly what she wanted, and how they would do it, and she knew exactly how to place herself for him. They looked to be long term lovers with a ton of experience doing exactly what they did. She and him walked from the edge of the bed a few feet out from it to an open area in her room. He was looking up at her and paying close attention, and knew exactly what time it was.
Anyway, he did stay lodged in her for 30 seconds to a minute. She was facing away from the camera. So, there was not a side view of his bits, at all. Smaller dogs sometimes seem to hump longer, like closer to 40 seconds of humping instead of 18 to 20 seconds, like some Danes.
