girlfriends first mfm

Was there when my GF took a 9.5" BBC.

I was kissing her as he fucked her deep
& the look on her face was a mix of total
erotic enjoyment, astonishment and what
I thought was pain.
I asked her if it was too much and she
replied "Oh god, NO! Put more lube on his
magnificent cock, I want him to give it
all to me, every inch, down to his big balls!"

The guy was a true Bull. Fucked her on
& off all evening, countless times &
positions. Then, as he was dressed &
leaving, he had her blow him at the door.
 
last weekend , my gf of over two years , had out first 3some , we talked about it almost from the start of our relationship , she readily agreed to , then covid hit, so nothings happened , untill recenitly , before we tried the bar thing, where she did talk to a few guys, flirted some, but no one really matched, i suggested to her id make a sls account , and i did talk to a few guys, finely narrowing it on one, last thursday she texted me saying .lets go to the city 40 miles away , i asked what she wanted to do she replied (anything you want to ) so i contacted that guy on the app, and explained what we talked about , made a date to meet with him at a dive bar. So on the hour drive i told her what i had planed , showed her his pic, she agreed , saying she was ready . So when there , we all had a couple drinks , discussed what we all liked, and went to his house . Once there when she came out of the bathroom, i took all her cloths off while kissing her , then turned her to face him. Ther kissed some then he led her to the bed room. Where we both took turns fuckign her , but ill admit i mostly watched, they fucked like animals , he cuming atleast 2 times and her over a dozen, , it was wild , over two hours in all . when we finely left , drove the hour home .Her and i talked about what happened, how things went , and if we might do it again. she seemed in great sprits about it all . once home i wanted to fool around with her some more ,but she said she was way too sore, so we just went to ....... the next day she was very sore, her clit, legs from holding theo up for so long, even her ribs hurt. and she seemed kinda drawn away . later she admited she felt like she did when she cheated on a old bf, years ago.. so my question is do you think she had post nut guilt,? And have other ladies experenced the same ?
I think she enjoyed it so much she feels guilty that she wants more......she realises how nice it I'd to have a much bigger cock than yours inside her.
