I am a guy and I had sex with my sister's boyfriend, should I tell her the story or get her to break up with him another way?

My sister's boyfriend came over, she was on her way from cheer practice, but work called her in. He was all bummed that he brought over a movie they were gonna watch, he had already brought over food. The only tv with a DVD player is in her room, my mom said it was cool so we hung in her room, he made a move to kiss me and I didn't block it.. I won't go into the details but he got me to give him oral sex and he humped me on her bed wearing her thong.. I did like the sex... I maybe BI but what should i tell my sis? and or just ask him to break it off?

  • Tell your sister but I don't know what's more wrong, you betraying your sister or wearing her thong. I'm just gonna say both and as much as I don't understand why you wore her thong I definitely know that I can go my entire life without knowing the answer to that or wanting to know.

  • Id get her to break up with him another way but if it comes down to it id tell her the truth. It may hurt your relationship for a while but itll be okay again eventually. Also if you are new to being bi and want someone to talk to, I'm here❤🌈

  • That’s hilarious and wrong all at the same time. 😂😂😂 media.tenor.com/.../tenor.gif

  • That's messed up! You betrayed your sister's trust.

    You'll have to come clean with her and it's up to her whether she wants to break it off with him or if she decides to forgive him. You don't decide whether she's still dating or not, you've done enough as is.

  • You engaged in it! Now take your medicine and come clean to your sister. If he did that with you it's probably not the first time he's done that to her And put her health at risk. If you care about her you will put her first.

  • Tell your sister so she can join you next time and you both share his cock and be his bitches, because you sound like one.

  • have you had sex again with him? Did you wear any more of your sisters clothes?

  • If you totally enjoyed all that he did, her boyfriend needs to make a choice between your or your sister... Did you wear your sisters thong the whole time? that's a bit far lol
