Lily finally upgraded your friendship to something physical ...and then promptly downgraded it again when she realized how disappointing you were in bed! She knows you're really into feet in general and so into her sexy feet in particular that you'll be willing to be her foot cuck just to get to stay involved in her sex life. So she strips down and teases you, before giving you a close up view of her playing with a much nicer cock than yours - including that footjob you so desired - as she taunts you with how you'll never get to have her in this way. You watch her get fucked and cum all over Thixon's dick as she shows you her soles before jacking him off so that you can see the creamy cum coating her pale feet.
