Woman catches her boyfriend and best friend kissing

A woman who got her boyfriend to hit on her best friend to see if her BFF would try to steal her man got more than she bargained for when her partner kissed the other woman and put his hand up her thigh.

Kelsey and her boyfriend Sam took part in an experiment with the To Catch A Cheater YouTube channel, which stages situations for couples in which one partner suspects there might be room for infidelity.

In that case, though, Sam was in on the experiment, and Kelsey’s best friend Britney was the one being tested. Kelsey wanted to find out whether Britney would be romanced by Sam if given the chance.

While Kelsey met Sam through Britney, she has been having trouble trusting her best friend.

‘She’s the kinda girl that likes somebody that’s already dating someone,’ Kelsey says at the beginning of the video. ‘All the guys the guys that she’s dated are currently in [a relationship].’

Sam then pretends to have spotted Britney by accident at a coffee shop, and after saying hello to her, sits down at her table for a bit of a chat.

Quickly, Sam gets on the topic of parties and asks Britney what she’s doing for Halloween. Sam then starts his charming offensive, telling Britney she should dress up as Selena because she’s ‘Mexican’, ‘cute’, and ‘bad’.

The video then cuts to Britney saying ‘My birthday’s tomorrow, by the way. Hint hint…’

Britney and Sam then engage in a flirty conversation, with Sam telling Britney he wouldn’t mind ‘stalking’ her on Facebook and asking her what she wants for her birthday.

Getting results: The experiment seemed to work a little too well at times, such as when Sam and Britney ended up locking hands

Contact: Sam at one point put his fingers on Britney's leg, brushing against her calf. Kelsey was shocked to see her boyfriend establishing this level of physical intimacy

Thus, Britney tells him she’d like some chocolate cake, and after a good amount of giggling, Sam offers to take Britney out, ‘just you and me’.

At that, Britney says she wouldn’t mind, as long as Sam doesn’t bring his ‘creepy’ friend who has apparently been sending her photos of his genitals.

This is the occasion for Sam to brag about the size of his manhood, telling Britney he doesn’t send ‘d**k pics’ because he prefers to show people ‘in person’.

He then asks Britney who she thinks would win a size contest, himself or the creepy friend, to which Britney says: ‘I mean, you, for sure.’

When Sam tells Britney: ‘I’d send you a picture, but mines [sic] don’t fit on the screen’, Britney does bring up her best friend and replies: ‘I just don’t think Kelsey would like that.’

‘It’s your birthday tomorrow, maybe I’ll show you,’ Sam adds.

‘Show your d**’ to me? For my birthday? Is that the best you can do?’ Britney asks, before adding a question of her own: ‘Do you want me to blow out the candle?’

Bold declaration: To assuage Britney's reluctance to kiss him due to his relationship with Kelsey, Sam told Britney he was planning on leaving his girlfriend

Sam tells him he would ‘love’ for her to ‘blow out this candle’, prompting Britney to declare: ‘You’re bad. I can see why Kelsey is into you.’

As the conversation continues, Sam puts his fingers on Britney’s leg, brushing against her calf. He does it again a few moments later, causing Britney to ask: ‘Why are your hands so soft?’ and to grab Sam’s hand.

Meanwhile, Kelsey, who is watching the experiment unfold, seems to get uncomfortable and appears unnerved to see her boyfriend touch her best friend’s leg not once, but twice.

Kelsey then seems absolutely scandalized to hear Britney tell Sam: ‘I think you already know I like you though. Wish I could find a guy like you.’

Sam then points out he’s right here, to which Britney replies’ Yeah, but you’re Kelsey’s.’

This is when Sam drops a bombshell, telling Britney: ‘I really plan on breaking up with her.’

Kelsey can be heard uttering a shocked ‘What?’ and asking the host of the YouTube program whether he told Sam to say that.

Demanding explanations: Kelsey makes it clear during the phone call that she's not pleased with how her boyfriend acted during the experiment

Not working: Sam tries to point out that he did it for their couple, so that Kelsey could clearly know what Britney was capable of, but Kelsey doesn't buy it

Meanwhile Sam carries on and ask Britney: ‘If I broke up with her right now, would you want to be with me?’

‘I have to think about it, maybe,’ Britney says.

At this point, Kelsey asks to stop the experiment because she needs to call her boyfriend. But not long after, Sam and Britney lean towards each other and end up exchanging a kiss on camera.

‘F**k that,’ a distressed Kelsey says. She then promptly calls Sam demanding explanations. ‘You f*****g kissed her?’ she asks.

‘I thought this is what you want,’ Sam says on the phone. ‘You set this up, this is for us.’ He hen further throws Britney under the bus, telling his girlfriend: ‘I’m saying now you know what she’s all about.’

‘But I got more than I bargained for,’ Kelsey tells him.

‘That’s your fault. You did this to yourself,’ Sam replies.

The argument does little to appease Kelsey, who promptly shoots back that he doesn’t ‘get to say that’.

Their conversation continues escalating and doesn’t seem to end happily for the couple. At the end of the clip, a seething Kelsey declares she’s more mad at her boyfriend than at Britney.
