update since the last time above.
since then we've met the new guy that she likes a lot several more times, same one i mentioned earlier. met him again thanksgiving weekend, and she got his bbc again for xmas. this was their fourth encounter, and with each they've gotten more comfortable with and into each other. we got a room so this was also their first time together in an actual bed; as it turns out we may not see him again for some time so i advised them both to take full advantage of the evening's circumstances.
a lot wound up happening. she sucked his cock for the first time - previously she said she didn't want to. after fucking him for hours in every conceivable position and taking three loads, she asked him to spend the night (also a first). she slept between us, with him playing with her body off and on as they slept, getting her so worked up that they fucked once more upon awakening. i think she knew that would happen by asking him to stay.
they've been using condoms so far, but the next day at home she casually asked me if I thought he would be ok with getting an std test...
pics are from that night.
