My little brother is still a virgin and I decided to personally take care of this aspect! He doesn't know yet, but I'm the one that took care of all our other bothers, all five of them (well, not at the same time, ofc). I know that my boobs are very sexy and a man simply cannot resist, so I wasn't too astonished when I caught my li'l bro spying on me. I was tucking in my boobies, the blouse I was wearing was kinda tight and I got uncomfortable. He was by the door, peeking silently just like a weird stalker. He's a virgin, so I guess it's more than normal to be curious, it's natural and healthy, in fact. I don't want him to be socially awkward around girls like most virgins are, I want him to be aware of his attractiveness and to be confident. In my opinion, to avoid the friendzone you have to be a very confident individual, girls usually friendzone guys that are too shy to ask what they want and to say what they think. Sooo, I decided to make out of my adolescent brother a mature confident man. I invited him inside, let him touch and play with my big tits. He obviously got a massive boner and I offered myself to "take care" of it. He was initially reluctant, but after he heard that this is like a tradition in our family, he accepted. He couldn't believe it at first, and kept asking if I really did this for all our brothers. I'm a helpful sister!:)) I think he accepted the blowjob I proposed out of curiosity, more than anything else, although he did sexualised me before: always peeking when I was changing my clothes... things like that. I began confidently to suck his big cock (out of all my brothers, his is the biggest), not hurrying, just letting him to get accustomed to the sensation. Then, wanting to surprise him I DeepThroated his cock, multiple times! He liked it and asked me to do it again, again, again! Guess it's something to have your cock DeepThroated by your own sister during the first blowjob you ever got. It was a long blowjob, an intense and huge pleasure for both of us. For me because I was guiding my brother on the road to sexual maturity, for him... finally his cock met somebody else than his own hand! I wanted him to have the full experience, so I decided to have sex with him. He was pretty good for a virgin, it's probably that huge cock. I rode his cock for a while, flapping my red curls. It was so pleasant, I wanted more, so we fucked doggy-style for a while, I had like three orgasms in a row! I was expecting him to cum sooner, but he resisted decently and was a gentleman: he first made me cum several times, then he came! He had orgasms before, masturbating, but he told me later that this one was unique, completely different. I cannot say I have done this out of pity or condescension, I had more fun than ever, even if I never regarded my brother as a grown man, with whom I might have sex someday. Now I see the things in a completely different light and am glad that I was his first
