As a surrogate. 
Brother stopped getting along with sis in high school and now that he's 30, he still only tries to deal with her on holidays. Which is too bad since he's married to her best friend, who still keeps up an active dialogue with her. His parents also keep bugging him to try and get along with her but he refuses and tries to focus on other things, like having his first child. Unfortunately, after years of trying and failing, he and his wife find out that the only way they can have a child is through a surrogate.
They're crushed but try to make the most of it and plan to have a date night later that week where they'll start looking through surrogates. To his disgust though, his sister shows up and his wife calmly tells him that she told his sister their problems and his sister volunteered. What's more, his wife likes the idea so much she practically says it's we as the surrogate or no one else.
Guy talks to his parents and they think it's a great idea, even offering to help pay for the bills his sister will rack up. He's flabbergasted but after a month, he relents. Sis gets impregnated and everyone talks about how great she is while brother tries to put on a smile, even though he secretly tells his siste he'll be watching her every step of the way and if she does anything that might harm the baby, he'll show her how he really feels about her.
Sister just giggles and then announced to everyone that her brother just invited her to come live with him and his wife. Brother reluctantly agrees after much pressure.
However, sis takes her duties seriously and works with her SIL and bro to do the best job she can while still doing some part-time work. Wife adores her and brother reluctantly thanks her. Things seem to be going great but after 3 months, things start to turn south.
For one thing, sis and wife are spending a lot of off time together and one day brother walks in on his wife seemingly rubbing his sister down. Sis denies it but wife admits she felt bad about how horny his sister said she had been and was thinking about masturbating her (the two of them had briefly had a sexual fling). A small fight occurs but things patch up and sis gets a dildo. Sister starts happily masturbating and even cleans her rubber cock in front of her brother and his wife.
She even starts going around the house nude when she can, much to brother's chagrin. Wife starts it too and brother starts to think he's the only sane one, even as his eyes are drawn to his sister's breasts.
It all comes to a head when brother is asked to help with sister's water aerobics, which she first does in a bikini and then strips out of that. Wife isn't around, so she openly teases him and admits wife has been dying for a 3-way and that she's noticed brother checking her out. He keeps angrily denying it until sis decides to get out of the pool. He grabs her by the hips and then hate-fucks her for all the stress she's been causing.
Brother is distraught afterwards but sis thanks him and calls wife to let her know what happened. The three then decide to start having a 3-way relationship until the baby comes and then possibly continue it.
I figured the reason bro hated his sis was because she seduced him while wearing a disguise when she was 18, with them both losing their virginities. Brother felt she had used him and just wanted something to always use against him, when she really did love him and wanted him to benched first...even though she went the absolute wrong way about it.
