Continued from Part 1....

My GF crawls into bed at about 4:30am, and I'm immediately awake thinking "oh no did I sleep through round 2?!?". Thankfully I didn't, she just missed our bed and T isn't a good cuddler I guess lol. Neither can fall asleep as she's still horny. We quietly get out a toy and have quiet but REALLY hot reclamation sex while she describes what happened and her plans for round 2 in the morning. I don't want to make noise and alert T, because I'm not sure if he'll feel awkward and not want round 2 then. We both cum and fall asleep.

At about 8:00am I barely wake up to her kiss saying she's gonna check on T. She goes up stairs and by this point I'm wide awake again. The next thing I hear are his moans and she sucks his cock. After this I learn she'd forgotten how big his cock is. Like I said, I'm well above average, but he's apparently at least an inch longer and thicker than me, which is genuinely huge. She can take me all the way in her throat, but she's gagging on his cock and still has another inch or two before her nose touches his skin. I hear a big groan out of him which was super hot. Then I hear some quiet words and movements. She's moaning for a while but I can't tell if he's doing down on her or fucking. I immediately learn the truth when I hear a shift and the bed post knocks the wall and the mattress is creaking. It takes every ounce of self control not to paint the walls in my basement at this point. But I held on.

Sadly not long after things go quiet again. I later learned T was getting stage fright essentially and didn't want to make too much noise with me downstairs even though she said it's fine. He was fucking her from behind in front of a mirror and wanted to rail the hell out of her, and she wanted it bad.

My GF came downstairs and gave me a warm and wet sloppy kiss. I knew she'd been sucking his huge cock and it was an incredible turn on. She said she's taking T to his car.

When she came back, she told me ALL the juicy details above while stroking me. I then ask her if she wants it from behind like she didn't get this morning, to which she enthusiastically gets on all fours.

Normally, it takes me a VERY long time to cum. I'm basically incapable of quickies which bums her out sometimes. I start slapping her ass, thinking of what went on above, and we both had HARD orgasms at the same time. My GF's pussy pulses like crazy when she cums and is unmistakable. Well fell over in exhaustion.

We checked in about all this later on Sunday. We both confirm we had a great time. She asks if I have any regrets, and I answer truthfully that my only one is that T didn't fuck her brains out like they both wanted. She had a fantastic time and is happy it happened, obviously I emphatically agree. Later she comments in a message that uncontrollable horniness has been unlocked. Obviously I'm jacked about this as I fantasize about her absolutely needing cock, especially if it isn't mine. She's crazy horny as it is and I can never keep up.

They have plans to meet again very soon. I may not be around which is both super frustrating but also hot because I know they'll probably destroy the bed.

TL;DR: My GF fucked a guy with a huge cock in the room above me, and I masturbated like crazy while listening the whole time.
