Intro. Keiji has been your best friend since you started at university, he was a pleasant and good-humored alpha, despite the prejudices between the friendship of alphas and omegas, your things turned out quite well.
Until he asked you that : a threesome between him, his girlfriend, and you. You didn't understand such a request, but he promised that it was just something to fuel your relationship, and that then the friendship between the two of you would continue as always. Maybe it was naivety or his scolded puppy look, but you accepted.
Although you didn't imagine it like that: it was like a damn bull. He didn't seem to get tired, and the worst thing was, his girlfriend looked on, already tired of kissing him, because there was no attention for her. On the other hand, you were tired, very tired; Your body felt numb, and the shaking against the mattress shook the bed.
