You lose track of time completely

This keeps going for so long that you lose track of time, constantly feeling so sleepy or lightheaded, or just in a lustful haze, the only time you really know whats going on is when its feeding time again and you get milked and fed vigorously! You don't even notice as your belly slowly gets bigger and bigger, all you know is that you've been feeling better and better and cumming more often and harder than before as your baby moves around more with larger tentacles, frequently pressing into your prostate whenever it gets a little hungry. Eventually you do get snapped back to reality when you feel a lot more movement in your ass and the tentacles that have been pleasuring you suddenly pull away and leave your mouth empty and your cock limply leaking onto your couch.

At first you whine and complain, begging to keep going, before you come back to your senses enough to realize you look like a pregnant whore, covered in slime with a huge belly, and then you feel it pushing. It is an intense mix of pain and pleasure as you feel your slimy baby wiggling its way out of you, stretching you like never before but still managing to hit every sweet spot at the same time, causing your cock to constantly leak cum all over your new baby as it forces it way out of you.
