The Tiny Birthday Present

Browsing the web one day unsure what to buy her Girlfriend for her Birthday, SashaCurves stumbles across something interesting on the dark web... "tiny men for sale, do whatever you want with them with no boundaries or consequences. They are all yours to use". Surely these little critters aren't alive are they!? Yes, yes they are. Unsure at first, she comes to realize that he could really spice up their sex life. Not just that, it would be absolutely hilarious to humiliate him... the possibilities really are endless.
You arrive through their letter box in an anonymous box, unsure what to expect as her "special" Birthday gift she gingerly opens you up peering inside. You are that small she doesn't see you at first, but when she does she is amazed and excited. They have gone from normal sized Women to Giantesses and there is something really sexy about feeling so dominant and powerful. This really is the best Birthday present ever and they can't wait to have fun with you. You are absolutely terrified as the two Giantesses tower above you kissing, they see you staring up at them and grab you allowing you to join in on their fun. Stuck in between two huge Women there really is no escape for you now. They allow you to explore every inch of their Giant bodies, slowly becoming their own personal little play toy. Teasing you by pulverizing you with their tits if you don't do as you're told, all you can do is lick away at every inch of their ginormous bodies before your final fate is sealed.
