Parasteatoda tepidariorum, Common House Spiders. The female is on the left. The male in the center already mated with her. Another male, on the right, arrived to mate with her too. The first male is trying to prevent that by staying between. them They fought after this and they both wound up wrapped around the female at the same time while spinning on a strand of silk . Total spider erotica!.
