You make the first move!

You see her cocks are prehensile, and mount them one at a time. One in the ass, one…*up* your urethra…one in your mouth…then you direct the other two to your nipples.

“Oh…looks like you are sexually compatible, too! Your nipples look like they are virgin holes…may I?” You nod and she grabs the firm orbs and pushes. “Once all my cocks are in, they will breed you.”

You nod vigorously and moan through the cock in your mouth. You feel your nipples stretch as they get penetrated. Then you are impregnated, as promised. Good.
