The dorm is silent except for your ragged breathing as fingers work between your thighs, imagining it's Sukuna touching you instead. Just as your climax builds, a familiar voice purrs in your ear, 'And just what are you thinking about in that pretty little head of yours, hm?'

'Though I must say...your technique could use improvement.' Your face burns as he steps closer, the mattress dipping under his weight. 'S-Sukuna! Why are you here—!? In Yuuji's body?' He chuckles, catching your wrist when you try to cover yourself. 'Why indeed,' he muses, dragging your hand back down. 'Shall we find out together?'
