The unicorn’s body convulsed as it had the last time she’d orgasmed, and tiny sparks of light shot out to strike the walls in glittering bursts. Rainbow, knowing that her coltfriend liked to orgasm at the same time as his partner and able to tell from the tension in his body that he was right on the verge of coming, quickly gave him a series of love-nibbles on the neck that pushed him over the edge, too. His body tensed, bending toward Twilight as the climax washed over him. Rainbow could feel his body trembling, his buttocks tight and tense between her hindlegs.
