Sandy's mind felt... tingly.
It was weird, like she could feel her brain being rewired. She had always been straight as long as she could
remember; she had only gone down on Kat because she wanted to please her boyfriend. She still desired someone
strong... someone manly to wrap his arms around her, and protect her. At least, until now.
She was still conscious, but when she tried to think about sexuality her mind went all fuzzy. It was like she
was on a sidewalk, but a few of the blocks were still drying. Slowly, though, she began to feel less hazy. She
thought of Dan's masculine features, his broad shoulders and strong pectoral muscles. She felt no reaction,
only a sort of indifference, at most a feeling of admiration, but no trace of desire. When she thought about
penises, or men having sex with her, she actually felt nauseous. She knew she should be desiring men, but they
did nothing for her now. Experimentally, she pictured Kat in the nude... her supple breasts, her wide hips,
her moist vagina... Sandy felt herself drooling and becoming aroused. She now actually wanted Kat, wanted her
bad... wanted to kiss her plump lips, slip her tongue between them... both pairs of them.
"You know you want me... just give in to your desires, Sandy. You want it. I want it. What's stopping us?"
Kat grabbed Sandy by the shoulders and brought her into a close embrace, locking lips with her, tongue
fighting tongue as they groped each other's curves. Dan felt himself growing moist, feeling his sister's
desire. Part of him knew he should be mad, his sister was stealing his girlfriend! But another part realized
that really, he was his sister; he was a part of her, and a part of any relations she might have with Sandy.
His thoughts were interrupted when he felt Sandy's finger probe into him, down his throat, filling him. Oddly,
this felt more fulfilling than when Kat masturbated with him earlier, perhaps because another person, someone
he cared for, was doing the penetrating.
Sandy withdrew her finger, and lay on the floor so that her feet faced those of Kat. She removed her skirt and
panties, baring her crotch. Kat seemed to sense what Sandy wanted, so she mirrored her position, legs spread
on the floor, feet to feet.
"I've always wanted to try this," confessed Kat, "but I never found a willing partner. Let's do it."
She lifted her right leg over Sandy's left, while sandy did the same. They slid their crotches together,
as Sandy's vagina grew larger and larger in Dan's vision. Sandy rubbed her vagina against him, her labia
touching his, in a strange sort of genital kiss. He could feel her warmth against his own, their fluids mixing
together. When their clits touched, Dan felt overwhelmed with bliss; Sandy's pussy was a perfect match to his
body.
Once the afterglow from their mutual orgasm died down, Kat spoke with Sandy.
"I've been thinking, and I have an offer to make you. One that concerns Dan."
"Yeah? What is it?"
"Well, I've been having a couple of second thoughts, given how things have gone. I could change him back if
you want, but you're my lover now, you wouldn't be attracted to him if I turned him back to how he was. There
are, however, other options."
"Other options?"
"If you like, I can transfer Dan to you. He can become your pussy instead of mine. I originally cast this
spell as a way of getting back at him, but it could get little disconcerting to think that he's down there
whenever I masturbate or pee. I mean, I'm his sister and the novelty may wear off eventually."
She paused.
"I suppose I could also turn him into a girl, but then it would be complicated." She sighed, "Perhaps I could
turn him into something less intimate, or add him to someone else..."
She looked at Sandy
"He was your boyfriend. It's up to you."
