Yes, mouth

You realize your prescription for Shanta is similar to that of Yvonne's save that Shanta would get cum on her face and hair, and Yvonne would do a lot more masturbating.

I wish each time Shanta swallows cum, it gives her energy and makes her very happy. I wish that after she swallows two loads of cum, any ailments she has are gone. I wish she was immune to sexually transmitted diseases, and I wish she could not transmit them either.

"Doctor?" she asks as you had gone silent making your wishes. "Can I get your semen?"

"Oh, sure. Kneel in front of me. Being on your knees is the best way to get semen."

Shanta kneels in front of you. You lower your pants and boxers, and she starts sucking you off while you play with her hair. She is very good at oral sex, and you don't last long before you cum in her mouth, giving her an orgasm.

As soon as she ingests the cum, Shanta feels happy and energetic. "Wow, that was great!" she says.

"It should be. Now I'll need to see you once every two weeks. Go and make an appointment."

"Thank you, doctor!" Shanta licks her lips.
