[Doushoku (Kuguri Oimo)] NTR Love -I'm The One Who Loves You-

Classmate Yui finds herself trapped and utterly at the mercy of a childhood friend who confesses "I LOVE YUU... SO MUCH" while demanding she declare "THE ONE WHO YUU CHOSE... WAS ME," escalating from forced oral service to a full creampie as he broadcasts every lewd detail over a phone call. The betrayed boyfriend stumbles in to witness her moaning "AH... YOU'RE GONNA CUM ALREADY? HOLD IT IN SOME MORE~" before being forced to watch his girlfriend enthusiastically service another man, her final mischievous text suggesting they skip school together leaving him utterly cuckolded.
