2 things:
1st: I agree that on shrooms in its apealing to rabbit fuck. My boyfriend and i have fooled around many a time on shrooms, very sensual and sexy. One time we lay there not doing anything, but only explored eachother's bodys. Taking the other on a verbal journy of what their minds saw/felt.
Example... in my sternum he saw a creek with running water which he followed to... whatever the trip may be. Very erotic. Very hot!
2nd: HIPPY FLIP. nuff said, haha. Shrooms and E are great mixture when you want a bonding night, if you foool around on it, which most liklley you will, it is fucking amazing. You are in another dimension, floating with no gravity, no motion, only feelings. HIGHLY recommend it!!
