Also, the other partner may indicate reciprocal interest by engaging in intimate behaviour of their own.
This type of extended foreplay can involve SMS messaging, phone calls, online chat, or other forms of distance communication, which are intended to stimulate fantasizing about the forthcoming encounter. The loser can, for example, be required to remove clothing or give the winner a sensual foot massage or any other thing that the winner wants to try.
A sensuous atmosphere can also be enhanced by candles, drinks, sensual food or suggestive clothing.
Role playing may involve the partners wearing costumes, to create and maintain a sexual fantasy.
For variety, the partners can make up a (sexual) story together.
Even a suggestion of the use of sex toys or the playing of games involving fetish, sexual bondage or blindfolding is an indication of sexual interest.
