You lay there next to her for a while. This is almost better then normal sex, you never thought you could orgasm from just arousal alone. If you had been in the normal world you would have just fucked her and ended it, but this was something way more intense. It was a bit frustrating at times, but you could definitely handle it.
You look over to Alex and kiss her again. Without thinking you say, "I didn't know you could make me cum without a penis." Then you remember that she doesn't know what that is.
Alex looks up at you. Those big perky eyes of her's look concerned, "what are you talking about?"
You think about what to say. Alex is a smart girl, she knows about alternat universes and that stuff. You say, "what if I told you I was from another reality."
Alex gasps, "What happened. I read about this stuff but I never thought... how are things different?"
You reply, "have you ever heard of genitals? Where a man has a special organ that he puts into a women?"
Alex replies, "On sharks and some other creatures. Did humans have them in your world?"
"Yep. Dudes had a tube called a penis that they stuffed into a hole between a woman's legs. Men were also more hairy and women had growths on their chests."
Alex seems shocked, "that sounds so gross, plus it would be so hard for a girl to change to a boy or vice versa. You must be happy to be here."
You feel your crotch a bit, feeling the lack of any penis, "sort of."
