Hyper-realistic digital illustration, 26yo adult female fairy with iridescent wings lying on her side in a fetal-like curl, wearing a sheer, gossamer silk slip pushed aside to expose her backside. A 32yo primary biological male is positioned behind her, his body pressed against hers in a tight wedge. He is performing slow, deep plunging thrusts into her anus, showing visible penetration depth and skin contact compression at the glutes. Her platinum hair is messy and splayed, her expression one of deep, rhythmic surrender. The scene is set in a shimmering fairy glade with floating embers and soft, warm amber lighting.
