[Usapesa] Shemale TF Skeb Comic 1 & 2

A late-night study session goes deliciously wrong when a bookish young brother deciphering a magic tome recovered from a dungeon accidentally triggers a gender-morphing spell on his doting elder sister, swelling her chest until her sweater bursts and leaving a very unexpected addition between her thighs. Mortified by her masculine voice and impossible new body, she collapses in tears until her sibling vows to undo the magic — and stumbles onto the cure: passionate anal sex with him reverses the transformation, though only from the waist up. With her enormous breasts restored but her stubborn hard-on unchanged, the siblings gleefully keep 'experimenting,' promising to feel good together lots and lots from now on.
