Like the title says. Kinks are biting, orgasm denial and over-stimulation. No non-con please, and no feeling guilty or w/e afterwards. Aftercare and cuddling would be great.

Bonus 1: At one point two of the others sex each other up, which is a huge turn-on for China.

Bonus 2: A/B/O dynamics; China is an omega in heat, and the others are alphas (if this bonus is filled, an additional scent kink would be very much appreciated).
