After their romp earlier, Cookie decided (through the haze of post-orgasmic elation and physical fatigue) that it'd be best if her and Sweetie stayed at Rarity's boutique for the night. Feeling the same, Rarity happily accepted on the condition that they "played" some more later.
As night drew closer, the three ponies gathered by a couch upstairs and prepared for an encore. Though Sweetie was undoubtedly nervous, worried that this second session may not be as good as the first.
