>MC, Heroine, and Bull all old friends
>Get together to drink, start placing random bets on things using card games, dice rolls, or coin tosses
>MC loses, bull gets to grope heroine
>The get together again, not drunk this time, but cuck challenges bull to another bet, again wagering heroine
>She gets upset with this, obviously
>Cuck loses, bull gets to kiss heroine
>Que montage of cuck betting again and again, always losing, thus heroine does more and more stuff with bull
>All the while, the cuck's getting into seeing heroine do stuff with the bull, as is she, now taunting him casually for his bad luck
>Bull bets on his next win, he gets to spend a weekend with heroine
>Cuck actually has a chance to win, heroine even sees this
>Purposefully loses, que 'Smug heroine NTS smile'
>During their weekend getaway, they video call cuck and the place a bet on a coin toss whether bull gets to come inside her on her risky day
>It's purposefully obscured and they say it came up for the bull
>Narrative climax, sex sex sex
>Heroine comes home, they embrace, the MC claiming he's lucky she's his
