I have had, I love you inside me
Stage 0 - no commitment: "How long you want baby?"
Stage 1 - return visits: "See you next week"
Stage 2 - she's cumming more often, the kissing's more involved, some (off-menu) extra(s) included for free: "I love you inside me"
Stage 3 - you spend more time cuddling, kissing and talking and neither of you care: "I want you to fuck me again". If she's indie maybe you overstay without charge, if she's in a bhouse or parlour she pays management for the extra time. You maybe have sight of her socials and private life.
Stage 4 - she's fucking you with intent, constant eye contact, snogging, licking, she's the sex monster, her words and noises are all sexual and she's using your cock to hit every spot inside both holes and the back of her throat: "I love you". Things may be going raw now and loads are wanted inside.
Stage 5 - Terror town! : You meet her family, she gets an abortion without telling you, you're overnighting for free, she cooks for you, you wake up in cold sweats without her, you try to break up and she gets violent or harasses you, "You're mine now baby" and you detect a little menace in her words, she dumps you and you can't handle it.
Stage 6 - You're fucked!
