Ex boyfriend (weed and sex)

So my ex boyfriend is my weed man and I️ bought weed from him today but later on realized my nails were too long for me to roll up. When he hit me up later and asked if I️ had smoked yet I️ told him no any why I️ didn’t. He asked me if i wanted him to do it and I️ said sure. What a stupid thing for me to do... he came over rolled it up for me and we both got High needless to say we ended up having sex and he cummed in me 🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️ this is the first time ever. And I️ was so shocked. Why did he have to cum in me while we’re not together. I️ hope this doesn’t turn into something else if you know what i mean 😩
