It's for your own Good.

You get all nervous and shaky immediately. The thought of Evelyn's hand touching you there... No, it cannot happen, they will discover that you have a hard-on. They will get mad at you for being a slut, Lily will get mad. You hide your bulge with your hands and try to hide your whole body from them.

Lily embraces you again. "It's ok. I get that it can be shameful, but it's the best way to make sure that you are healthy..." She hugs you tightly and her hand caresses your chest with care. "We can leave you alone for a while if you need to... take your time."

"I don't want to... it's wrong." You say.

"You... You never...?" Says your sister.

"No!" You say. "I'm not a... a..." You know you are lying, you remember what happened last night with the wicked Amelia, you remember that dirty experience when she put your dick in her mouth. Why would anyone do that? Why did it feel so good? "I'm not supposed to touch myself... It's sinful. I... I have to wait for my wife."

Your sister hugs you even tighter. "You are a sweet good man, and someday you will make a woman very happy... but this is not like that, this is a health issue for your own good. You are not cheating anyone...Evelyn here is a profesional, she is used to these things. You are safe with her... and with me."

"Indeed." Says Evelyn, still with the same motherly but professional tone. "Most boys feel the same as you. They feel that it is wrong to touch themselves, even if it is a perfectly normal and healthy behaviour... You are not the first one that I have encountered... If you so wish... I'm more than capable of assisting you if that makes you fell better."

"But... we are not married..." You say.

"And we don't need to be. This is a medical checkout, we can discuss the possibility of our wedlock in another time, sweetly." She smiles at you again, trying to make you feel confortable, and she weirdly succeeds. "I'll even wear some latex gloves, so I won't be technically touching you..."

Lily speaks close to your ears, still hugging you, still touching your naked chest. "I can do it too if it makes you feel better... You won't have to marry me later, don't you?"

"But... but..."

Her hands linger over your chest. "Mark, I want you to know that you are safe here, no one will do you no wrong... This is for your own good: take your time. We will do it when you are ready and you will be the one to choose how. It can be Evelyn, it can be me or we can leave you alone. You choose."
