I had sex with my girlfriend’s sister while she was ill upstairs – I couldn’t help it, she’s stupidly hot & came onto me
A MAN has revealed that he slept with his girlfriend’s sister whilst his partner was ill upstairs.
After a night out with friends, the man confessed that he went back to his girlfriend’s mother’s house – but things took an unexpected turn when his partner’s sister came onto him.
Keen to open up on the situation, the anonymous man took to social media to share all, leaving many open-mouthed.
Posting on Reddit, on the r/relationship_advice thread, the man, who writes under the username @snatchmountain, titled his post ‘I slept with my girlfriend’s sister’.
He then explained that he cheated on his 21-year-old girlfriend with her ‘stupidly hot’ sister, 27.
The man confessed: “Basically went on a night out with my friends, my girlfriend and her sister with her friends. Good night, all had a good time.
“I was staying at my girlfriend’s mother’s place after, so was the sister.
“We got home late and we were all p****d, but decided to stay downstairs and watch TV before going to bed.
“My girlfriend went to bed after 20 minutes or so as she was knackered and felt ill.
“After 10 minutes her sister sat next to me and we were watching TV, all good and she then just came onto me.”
The man revealed that the sex was ‘incredible’, but now he doesn’t know what to do, as he added: “She is stupidly hot and I just couldn’t say no. We had sex and it was incredible.
“She has two kids which makes it even worse.
“After doing it a few times we both went to bed. I went to bed with my girlfriend, the sister in the spare room.
“In the morning, when we were all having breakfast it was like it never happened.
Four red flags your partner is cheating
Private Investigator Aaron Bond from BondRees revealed four warning signs your partner might be cheating.
They start to take their phone everywhere with them
In close relationships, it’s normal to know each other’s passwords and use each other’s phones, if their phone habits change then they may be hiding something.
Aaron says: “If your partner starts changing their passwords, starts taking their phone everywhere with them, even around the house or they become defensive when you ask to use their phone it could be a sign of them not being faithful.”
“You should also look at how they place their phone down when not in use. If they face the phone with the screen facing down, then they could be hiding something.”
They start telling you less about their day
When partners cheat they can start to avoid you, this could be down to them feeling guilty or because it makes it easier for them to lie to you.
“If you feel like your partner has suddenly begun to avoid you and they don’t want to do things with you any more or they stop telling you about their day then this is another red flag.”
“Partners often avoid their spouses or tell them less about their day because cheating can be tough, remembering all of your lies is impossible and it’s an easy way to get caught out,” says Aaron.
Their libido changes
Your partner’s libido can change for a range of reasons so it may not be a sure sign of cheating but it can be a red flag according to Aaron.
Aaron says: “Cheaters often have less sex at home because they are cheating, but on occasions, they may also have more sex at home, this is because they feel guilty and use this increase in sex to hide their cheating. You may also find that your partner will start to introduce new things into your sex life that weren’t there before.”
They become negative towards you
Cheaters know that cheating is wrong and to them, it will feel good, this can cause tension and anxiety within themselves which they will need to justify.
“To get rid of the tension they feel inside they will try to convince themselves that you are the problem and they will become critical of you out of nowhere. Maybe you haven’t walked the dog that day, put the dishes away or read a book to your children before bedtime. A small problem like this can now feel like a big deal and if you experience this your partner could be cheating,” warns Aaron.
“When I now have sex with my girlfriend, I imagine it is with the sister.
“What the HELL do I do?! Such a f****d up situation.”

Many were horrified by the man’s actions and encouraged him to call it quits with his girlfriend.
