Give him a little "encouragement"

Still sitting on the bed you throw your blanket aside and show him your beautiful naked body again, this time you deliberately show him all your private parts including your perfectly shaven cute pussy.

You move to the side of the bed and sat there with your legs on the floor, and then slowly spread your legs, while rubbing your breasts and playing with your nipples.

"What's the matter? I know you want it..." You tease him more.

He gulped and cover his crotch, you know that his boner is even harder than before, and it's possible that it's now so hard that it's painful.

You flick your forefinger, inviting him to come to you, and he slowly did, inching himself towards you, still hesitating about what to do and how to react, and finally he's right in front of you, his eyes shyly absorbing the sight of your magnificent body and beauty.

Then you did something that he never expected, you use your finger to touch the bulge of his pants, and then rub it up and down, you're surprised that his cock is so hard, it's like touching a rock.

The moment you touch it he grimaced and when you rub it he moaned silently, then you grab one of his hand and put it on your breast, he slowly but hesitantly began kneading your breast.

His touch felt very inexperienced, and you guessed that he is still a virgin and never touched a girl like this before, but slowly as he became more confident, he reached your other breast and masages it too, but still with the same amateurish touch.

Even though he's inexperienced, you do felt pleasure as he did this even though just a little, thinking that you were actually doing this taboo thing with your younger brother made the whole thing more exciting, so you pull down his pants.

He was too engrossed with touching your firm beautiful breasts to care that his cock is exposed and you can see clearly now how big his cock is.

You gently caress it and that made him shiver with delight, you hold his cock and then stroke it slowly, causing him to close his eyes enjoying the feeling while his hands are touching and rubbing your nipples.

You kept a steady rhythm and after a while you stroke him faster, and he was moaning and kneading your breasts harder, it wasn't long before he cums and you made sure he cums on your tits.

You then rubs his semen all over your tits while looking at him and he was looking at you with disbelief.

"Wow... I... I couldn't believe we just did that... I mean... you... man... that felt too good sis..." He said to you.

"Did you like it?" You asked him.

"Hell yeah... I mean it's much much better than doing it with my own hand, it felt completely different... I mean... it just felt super good... shit... I still couldn't believe it..." He innocently said it to you.

"Well I'm glad you like it... but never ever tell mom and dad about this ok?" You told him.

"Of course...! They'd kill us if they ever finds out... but... can we... like... you know... do it again... I mean... if you want to... of course but emmm..." He said shyly.

"Sure... but only if you also make me satisfied too." You said to him.

"Ok... of course... I wouldn't want to disappoint you." He nodded in agreement.
