Rachel removes her underwear,gesturing for you to come closer and as you do, grabs your head and rams it inside of her. She moans as you're pulled slowly into her vagina until you curl up within your friends womb. Rachel caresses the bulge you've created, still moaning as she moves to finger herself.
On the inside, along with hearing Rachels moaning and getting jostled by her movements, you can also hear the sounds of her heart beating and her digestive system that you were in previously gurgling away.
After a while, Rachel is too tired to let you out and falls asleep with you still inside her womb.
