Well, yourself

He looks at you, full of hope. You walk to him and kiss him. He remembers your lessons and immediately puts his hands around your waist and uses his tongue. He's getting better and better at it.

"Very nice" you smile "I'm glad you didn't forget. I know that you are really horny, but I want you to control yourself, okay?"

He nods his head.

"Sit on the bed" you order.

He does that and you look straight into his eyes. You walk to him slowly and seductively, seeing that he looks at you in adoration. You almost feel like a Goddess now. When you are so close to him that your bodies almost touch each other, you smile. You raise your foot and touch his cock. Oh, he's hard. Then you sit on his knees and kiss him again. Then you start to undress him, you take off his shirt, slowly. And then...you lose control of the situation. He pushes you down on the bead, but he still have enough self-control to not tear your lingerie up. You are naked in less that a minute, but then he remembers that he shouldn't rush it and smiles at you. You wonder if you should scold him for doing what he's done, or praise his courage, you yourself told him that he needs to be self-confident after all. You decide to wait and see whet he'll do next.

It must cost him all his strength, but he isn't impatient, he kisses your body all over. Your neck, your breasts, your belly...it's nice. Then he kisses your legs and feet, and licks your pussy a little. He's still a little clumsily at that, but he makes you horny anyway.

"Oh Bro" you moan.

"Yes?" he asks with a smile.

"Do it. Fuck me."

He obeys. He enters you slowly, and then he starts moving his hips, still slow. You are giving him tips.

"You need to achieve a steady rhythm, yes that's good. Ooooh, you just hit a right place. A little faster. Not that fast. Good. Faster. Oh, fuck, very good!"

Yes, now he's fucking you in medium peace, if he keeps it up, he's gonna make you cum, you love how his cock enters your pussy, it is just the right size. With his every move you feel that you yourself are getting more and more excited. But then he loses control of himself, loses his rhythm in search for a quick orgasm.

"No. Slower, slower, damn you" you order him, but he's too far gone. He fills you with his cum. Fuck! And you were so close to cumming yourself.

"I'm sorry sis" he really looks like he regrets that he didn't manage to keep control of himself to the end.

"That was much better" you say. You are frustrated, but you have to admit that he made great progress "but not good enough."

Your fingers will have to suffice, this time. But next time...
