Input: Text: my so and i went to a sex shop and i picked out a toy that was much bigger than me on purpose. the sex and fantasy was great with it, but it obviously stretched her out. then a week later, i went back and bought another toy, a bigger version of it and it was black... i blind folded her and used the new black toy instead and she definitely enjoyed it not knowing it was the new one. when she found out it was a different one, she was shocked and amazed. to cut the story short, she was definitely much looser, but now when we do it normally without the toys, i've noticed she is not as tight as before. it was the biggest object that went into her.

TIFU by buying my SO a dildo that is much bigger than me... scratch that 2 dildos...
