My Man Mickey.

Blond Mickey and his swarthy buddy pick up two undergrads at a beach and slip them some proverbial mickey finns in their drinks. The lecherous duo abuse the inebriated youngsters, fingering and rimming and plugging their juicy, plump, tender butts in cherry-picking salaciousness. Laughing, the evil duo leave behind the magic elixir which the abused youths discover upon wakening. Finding the perpetrators, they lure them back to their place for a tables-turning romp of tangled limbs, cocks, and asses.
