Yeah, it must be nice to be able to come while being fucked and I kinda wish I could. As you said, having two body parts that can bring you to climax would be good.

My all time favorite sex act is sucking cock. As a cocksucker it is really fine to encounter a man who is really turned on by being fucked when there is a third party present to fuck him while I suck his cock. The combination of prostate stimulation by the fucker and my oral stimulation to his cock brings him to a massive orgasm that shakes his whole body and he unloads a huge load of jizz that is a cocksucker's delight.

As for women, I don't know, I've never done anal with a woman. Since they do not have a prostate I wonder if they get the same kind of pleasure. It's not difficult to find heterosexual anal porn, however, even a woman taking two penises at once, one in the anus and one in the vagina. Or even a third in the mouth.
