Bathtub Love (2000)

Bathtub Love: a bathtub / hot tub game for lovers

Rub-a-dub-dub, make love in the tub! From the package:

"Bathtub Love is an erotic foreplay game that allows lovers to explore the sensuality of sharing a nice warm tub. Each bubble [plastic capsules like those from vending machines] is filled with four actions that vary from playful to naughty. Place the bubbles into the tub; then pick up one of the bubbles. Randomly select a romantic action from the bubble and perform it on your lover. After performing the action, set it aside, re-seal the bubble, and return the bubble to the tub. Your lover then takes the next turn and play continues until all entries are carried out or until foreplay has turned into something more. Both players win by sharing a fun and romantic time together."
