According to Primal Hardware (a sex toy company in Franklin, Newhampshire), a lot of people fantasize about being full of alien eggs or having eggs inserted into them.
This new sexual fetish is called Alien Impregnation Fetish.
So, Primal Hardware makes eggs out of gelatin, you insert them into the bottom of the Ovipositor sex toy, keep adding until they pop out inside you.
