Have you ever had sex with a sibling's partner or ex-partner?

Question

You're a 19 year old girl and you still live at home. So does your 21 year old sister. She's been dating this guy for 5 months and you know that they are having sex on a regular basis. You aren't dating anyone at the moment and, admit it: you feel just a bit jealous. He is a handsome guy, athletic, finished college three years ago, has started a career, has his own house, drives a nice car, etc.

But you'd never do anything with your sister's boyfriend, would you? One Saturday, he invites his sister over to his house for a cookout around the pool. She invites you along and you don't have any other plans, so why not? You arrive and within a few minutes, your sister gets a phone call and she must go fill in for another employee who called in to work because they are sick.

You stay at the boyfriend's house and he offers you a few beers. You're both in the pool and you start having a "splash fight" and soon he is holding both of your wrists to restrain you. As you look up, he is looking onto your eyes, then he looks down as if he can see through your bikini! You know he wants you, and you are feeling rather horny, too, but. . . this is your sister's boyfriend!

Could you say no? Have you ever been in a similar situation and said "yes?" If you said yes, what happened: kissing, making out, or sex? Did your sibling ever discover what had happened. Or did any of this happen with your sibling's ex-partner after they had broken up?

Honestly, the last time my brother and I liked the same girls was high school. Most of those gals showed little interest in him, and even less in me. So this was never an issue. He's married now, and there is no way in hell I'd want his wife for myself.

Then again, the gals I've been interested in from college-onward, he'd probably assume most of them were "losers" somehow. (He was always very prejudiced against any gal I would find attractive.)

Now, my two other brothers:

The one is 17. His girl is a blasian chick from the Detroit area who is about 15. I may like blasian, but 15 is way WAY too young in my book. So... I'm gonna leave that one alone.

The youngest brother I have is just about to enter high school this fall. There is no way I'd take a girl from him, assuming he even got one. He's always been shy around girls, and is still fighting hard for the right to be single and not have one. Even if he caved and got one, she'd be less than half my age. So... not happening.

Where is just absolutely freaking wrong It's cheating but it's worse because you're a sibling.

Trashy bitch move on the younger sister's part. I would never do that. If someone's in a relationship, you stay the hell away from them even if they're hitting on you.

Thankfully I will never be in that scenario since I only have brothers and they're all straight. However, becoming involved or meddling in some way with a sibling's relationship is a terrible idea that fucks everyone over in the end. I learned that the hard way.

Absolutely not. I value my relationship with my sister way too much to jeopardize it that way. Plus, knowing that someone had previously been with my sister would gross me out a little in the first place.

Angry_Mango · Answer

my bro and sis both dig chicks anyhow and I dont lol.

heavenonearth · Answer

Never have and never will, but I only have a brother anyway, and I'm not interested in girls.

I consider my best friend a sister though, and neither of us would mess with each other's partners or ex's. It's just off-limits.

vishna · Answer

Considering my sibling is married, no, I hope to never do that. And she better not do it either.

I think you've been watching too many movies 😛

Mustachekitteh · Answer

Nope never did that and I wouldn't do it. Any of the dudes my sister dated would never be guys I would ever want to be with.

nikki_24 · Answer

06CuriousMind · Answer

i would probably be tempted. I dont see the problem with getting together with other peoples ex's, even if they are close to you. if it didn't work out between them, then they are fair game. depending on how it ended of course

GrantS · Answer

I won't and I can't, unless my sister makes a drastic life changing choice at age of 21

TacosRAwesome · Answer

For me that's almost incest. Which makes it gross.

datgirl · Answer

I was young (14) she was 21, which at that age is a big difference. My brother was away at college and it just sort of happened over the course of 6 months. The first time just sort of happened, but she stayed with us as my brother (we shared rooms) still lived at home technically, but was gone a lot. I felt bad, because looking back I didn’t have the capacity to control myself and we were clearly attracted to each other. Top top it off we didn’t use protection and she wasn’t on birth control. I ended it after about six months after we nearly got caught! I feel really bad to this day, they broke up shortly after for other reasons and I abstained from sex until college. We also never spoke to each other about our sex life. We just would do it about 2/3 times a week. I regret it to this day.

Never with my own brother's ex's but I have twice had sisters as girlfriends, though not at the same time. Both times it was the younger sister first then the older one. One was about six months later, the other two years.
