I swear we're not an ERP group - Laser tits

Short, 4 session campaign, DM was drinking a bit for the first session so we knew to expect shenanigans
During a bit of down time the first session we ended up joking around and trying to get a feel for each other's characters
Eventually our bard makes a joke about how every elf is flat chested and points to our ranger as evidence
She takes offence to this and claims she's just wearing a bra of holding
The bard calls her out on it and she goes into her tent then comes back now sporting a huge set of knockers
A bit later she somehow fumbles three skill checks in a row and the DM rules it's because she kept smacking herself in the face with her tits.
She jokes about this being why she always wears the magic bra, the bard makes a joke about how her breasts seem to have a mind of their own, and I manifest sense minds as a joke
The DM rules they do, laughter abounds
As the session went on, me and the ranger ended up separated from the rest of the group and after a bad encounter, my character ends up bleeding out, no healers/healing items around so I'm gonna die
Jokingly say I true mind switch with the elf ranger's tits
DM lets it pass
So now I'm playing a set of huge tits on an elf's chest with psychic powers
It's a bit uneventful as she tracks down the rest of the party until she explains what happened and they started making jokes about how she should let me out to breath/see.
We try to fix this by resurrecting my old body and letting me swap back into it.
Instead what happened was whatever intelligence used to be in her boobs refused to be resurrected, it had already spent a century on an elf's chest, it didn't want to spend several more.
We had a few encounters after that, I stilled played my role as the blaster by shooting various types of mind lasers at things, a number of them had a tendency to destroy whatever top she was wearing and after a few jokes about extreme nipslips she eventually decides to just go topless joking about how she doesn't have to worry about her girls flopping around now that she has a telekinetic bra.
We tried to avoid killing humanoid opponents, as me and the elf were trying to find an enemy whose body I would like and who she wouldn't mind having a part of her for the rest of her life but we ended up rejecting each for various reasons
The third session was heavy in diplomacy and infiltration, sure being a topless elf and her huge occasionally glowing tits kept us out of more high class places but it opened a lot of doors, especially with powers like attraction helping things along.
There was one indecent where we got caught where we shouldn't of been by a few guards and she tried to play herself off as lost and a bit of an airhead while I use charm person. All but the leader failed their will save so she tried a bit of seduction to get him to let her go, midway through after she ended up shoving his face in her cleavage I manifested assimilate and after a bit of silence she let out a small giggle and said "oops, he fell in" before walking past the rest of the stunned guards
I never (permanently) mind switched out of there, though later someone raise the question if I could swap into any other body parts of hers, the answer turned out to be yes but it wasn't as "roomy", also she refused to go bottomless.
In the end my psion spent the rest of the campaign (and going by the epilogue we wrote, the rest of his life) as a topless elf's laser firing titty turrets
