well i don't remember the first hard on, but i ure remember the first ejaculation.
It was one evening we had guests and all the bedrooms were full, so i slept with my three year older sister. She was 17, i was 14. She was a hot blonde, a bit slutty. In the middle of the night i had a hard on, and got the idea to investigate the feminine anatomy. So i slowly removed the cober, and slipped my hand between her legs... she was shaved, and she spread her legs slightly, pretending to be asleep. I fondled her and then suddenly i noticed her hand was slowly surrounding my dick. I didn't know what happened, it was good, didn't want it to stop. No thoughts, just pure innocent lust. She then did slide over a bit, and venture toput her lips around my hard dick. She sucked a little and i could not resist very long and jerked a massive first dosis of sperm in her mouth! I guess she swallowed it. I remember her slutty smile in the twighlight. We lay down without a word, And after my heart had seized to race at thousands of bpm, i slept. We NEVER ever talked aboutn this incident, and it never ever happened again
that was my first ever ejaculation, and oh boy was it good.
