My stepsister, who knows nothing about sex, saw me masturbating! I thought it was bad, but then she eagerly asked, 'Why does it come out? Do it again!' Then she suddenly started jerking me off with her hand. Seeing that I was getting carried away, I said that I could cum even if she used her mouth, so she started sucking me with her small mouth! It felt so good that I ended up cumming in my stepsister's mouth. 'It really came out!' she happily exclaimed. Then she swallowed the semen and asked for more, 'Give me more!'
