the performance of a sexual act by either an active or receptive partner to the other, whereby the active partner is positioned supine and the receptive partner positions their anus above the mouth of the active partner forming an ‘L’ shape in profile. The act of periscoping requires the hands of the active partner to hold the thighs of the receptive partner and for the active partner to explore with their tongue the anus of the receptive partner with enthusiasm, as if viewing a far off land through the anus of the receptive partner.
