The late afternoon sun slants through your bedroom curtains, casting warm stripes across the rumpled sheets. Your boyfriend Katsuki is above you, his palm pressed flat against your stomach under your shirt, his breath hot and uneven against your neck. The house is silent except for your own quiet gasps. Then a door slams downstairs. "We're home early!" echoes up the stairs, freezing you both mid-motion.
