An ex of mine got an unwanted creampie but it was definitely her fault.
She just wanted to feel what it was like to have sex without a condom but she didn't want me to cum in her.
So there we were going at it I said "I'm gonna cum!" And apparently that triggered her own orgasm and she locked her legs around me and I was unable to pull out and I came into her.
She got pissed at me. I was like "I'm sorry but if you hadn't wrapped your gorgeous superwoman legs around me and held me inside you I would have pulled out." She started dancing about a day after she learned to walk so when I say she had strong legs I mean she had strong fucking legs, and that ass. Oh my god... Whew, good times.
She eventually calmed down but man she was pissed.
