i was seen masturbating by my step-sister who has zero sexual knowledge! when i thought it was bad, she said "how do you do it? do it one more time!" with great interest!? furthermore, my step-sister, who casually asks "is it okay if i rub it with my hand?" and starts handjobbing! i, carried away, said that even if i do it with my mouth, it will come out, and she started taking it in my small mouth! i ejaculate in my step-sister's mouth because of the overwhelming pleasure. "it really came out!" she said happily. furthermore, she swallows the semen that came out and says "give me more!" and comes looking for semen!
