It seems you girls have fun... well that's good for us, your readers
As this game will come to an end, even you may restart it another time for sure, I had another idea. You'd need 3 vibrating "eggs" with remotes but it can be played with one only, if you agree to sahre and use the same.
With 3 eggs:
Each of you insert one in her pussy of course.
From there, several possibilities:
- You pick up the remote from each other's egg.
- The winner of some game gets all remotes.
- The remotes are hidden and to be found.
No need to tell you what to do with them, right? But I foresee many interesting moments at lunch or the cafeteria. In the labs too, of course.
Then games can be added on top, like who climaxes first wins, or the opposite.
With 1 egg:
It could then be the forfeit of a loser. She will wear the egg inside of her vagina and the 2 others will play with the remote.
The egg(s) will have to be worn a full day, or even longer to be interesting. It can be spanned over 3 to 6 days, one for each of you, depending who has the remote and for how long.
Another idea:
Somewhat similar but with a dildo long enough to be inserted deep and be attached with a crotch rope or taped to the thigh of one of you. Now is it for a loser or a winner?
Or the 3 of you could do the same on a certain day. Why not at the conference? You'll be dressed casually and it could be easier to conceal a crotch rope.
A variation could be done with a smaller dildo, taped lightly, that would have to be "stolen" in the most inappropriate place, like a crowded one. I recommend lube to avoid injuries if it is pulled harshly.
For the hotel:
Since you're quite the exhibitionist bunch, you should have a race there:
Hide a dildo on the last level of the buildling.
Then either from your rooms' level or starting from the lowest floor accessible, you will race to get it. It can be against a timer, one after the other, or it can be all together at the same time.
The trick is to get the dildo, insert it, and rush down to one of your rooms. And of course, you should be either all naked either dressed up in suggestive, skimpy lingerie: maybe even with heels so you don't run too fast in the stairs.
Taking the staircase is what comes to mind first, right? Yet, the lift isn't out of use, for as you do a race, one can be daring enough to take the lift to go faster. Naked obviously.
For more fun, the dildo should be hidden in the hallway somewhere. But then it means the races will be done by 2 of you and there will be Sab+Silvy, Sab+Eli, Silvy+Eli.
As a forfeit for the loser:
She will have to insert a cup or glass in her pussy, lay on her back on a bed or better on a table, legs spread wide, while the 2 others will have a mini game at throwing pistachios or peanuts into the glass. The one who lose, or win depending on your mood, will have to eat them from the cut, has she will lay down on the floor while the one with the cup inside of her will try to pour the content into their mouth.
I hope I'm clear enough, esp for the last one. XD
