Chrissy Marie is arguing with her boyfriend. Apparently she had cheated on him with his own brother. "I've already said I'm sorry, what do you want me to do" she asks. When he tells her he has an idea she assumes he's talking about something sexual. She gets a playful look and says she'll do anything. He says he knows how to make things even, but she'll have to trust him. She smiles seductively and agrees. In the next scene he asks Chrissy to strip naked and sit in a chair. He chains her arms to down and starts tying her legs together. She had no idea he was this kinky, but she seems excited. Once her arms and legs are tied up he locks a ballgag in her mouth and plays with her perfect tits. Chrissy is enjoying herself so far, but her demeanor quickly changes when he picks up her cellphone and tells her he's inviting someone else to come over. He explains that since she slept with his brother, the only way to make things even is to have sex with her sister Megan. He sends Megan a message from Chrissy asking her to come over. Chrissy struggles and moans in protest as he continues playing with her body while they wait for Megan to get there. Megan walks in and sees Chrissy tied up and gagged. Instinctively she rushes over to help, but the boyfriend grabs her from behind and drags her onto the bed. Once Megan is also tied up, he explains the situation to her. Megan is very unhappy about the idea of having sex with Chrissy's boyfriend, but he isn't going to let that stop him from saving his relationship. Once he has Megan naked he starts handcuffing her. Realizing that she's going to be having sex soon whether she protests or not, she offers a compromise. She asks if it would be good enough if she blows him instead of having sex. He reluctantly agrees and lets the handcuffed Megan suck his dick while Chrissy is still tied up and made to watch. Megan sucks his dick with skill, but gets tired before she can finish getting him off. She asks him to make Chrissy finish the job since she's his actual girlfriend. He isn't happy about this. He tells her the deal was that they'd skip sex if she sucked him off, and since she didn't finish the job they would have to fuck. He roughly positions Megan on all fours so he can fuck her doggystyle. He takes Megan roughly. She takes his dick like a champ and seems to be getting a little into it. She eventually says to Chrissy "I see why you fuck this asshole, this is some good dick". Chrissy is still struggling and making a lot of noise in protest as she's made to watch her sister and her boyfriend fuck right in front of her. She seems to get even more upset when her sister starts enjoying it. Megan gets fucked until her knees start giving out. She eventually drops onto her stomach as she's getting dicked down. The boyfriend flips her onto her back and starts plowing her from on top. He eventually blows his load all over her stomach while his unfaithful girlfriend Chrissy does her best to scream in protest through her gag.
