"You know, staring to you like this began to make me a little excited" Beth giggled rubbing her dress between her legs, "so why don't we have a little fun?".
Melanie watched Beth as she was completely paralyzed with her magic, looking how her roommate's clothes began to disappear like she did with her. Beth had a nice pair of B cups boobs way less bigger than Melanie's, but had a nice body and waist with a hairy but trimmed vagina.
"Do you like what do you see?" Beth giggled standing naked in front of her only wearing her witch hat and black long stockings. "I don't know if you're into girls, but there's a first time for everything".
Beth used her magic to make Melanie stand in the air in the doggy style pose, begining to lick her pussy.
"B-beth what the hell ar-are you... Doing!" Melanie yelled as she moaned and blushed, completely embarrassed in her current situation.
"Don't worry, this will get way better later" Beth inserted two fingers inside her and she kept licking, Melanie could do nothing but wishing for her ‘torture’ to end, just moaning in the process.
"Let's change things" Beth used her magic again now to make Melanie lay on the bed, the witch sat on her making both of their pussies touch, Beth started to get really wet as Melanie that didn't want to admit that she was beginning to enjoy it. Beth moved making both pussies rub each other, stimulating their clits. It didn't took long to make Melanie cum, squirting all over the bed.
"Ha! I knew you would like it~" Beth said staying completely normal as Melanie was very exhausted. Beth used another spell to make Melanie recover her energies, "oh girl~ we have one more thing to try, it is a spell that I learned recently and I HAVE to used with this perfect body of yours that I can't wait more" she laughed, making Melanie wonder what was all of this about.
The witch's hands started to glow with a purple aura she moved to her crotch, looking how that aura lengthen making Beth grow something between her legs, a real cock. The glow stopped and therefore the growing of Beth's new equipment, a 8 inches dick with testicles that replaced her vagina. "Ready to test our new little friend~" she grabbed her new asset rubbing it with Melanie's sex.
Melanie again could do nothing against the witch's powers, just feeling how a big penis went to her insides, feeling every inch filling her. Beth slowly began to fuck her even harder every second, she couldn't enjoy it more. "Oh god Melanie, your body is just perfect" she felt how her ballsack slapped Melanie's crotch as they had sex, "I need to make it all mine" Beth apparently never saw a good body like Melanie's, making her even harder.
After some minutes Beth couldn't wait more, she entirely filled Melanie with her seed, squirting shots of cum from her pussy as she pulled out the cock.
Beth stared and her dripping penis, cleaning the cum with her fingers and licking it. Then she removed the magic from Melanie making her able to move, but was exhausted again to do it.
"I'm glad you enjoyed every second of our session as I did, but I have many other plans for you, Melanie~"
