Sucking in a deep breath, Lily felt the first wave of pleasure erupt through her pussy. It was almost too much considering how badly she'd been waiting for this all day. Her back pressed deep into the wall behind her as she covered her mouth with both hands to prevent the sudden moans and whimpers from giving away what was happening in the shadowed corner. Lily's eyes were beginning to roll back from the skillful tongue plunging into her body and licking up all the excess juices she was producing. The process was enlightening, elevating her to higher plateaus of mind numbing ecstasy. The second orgasm erupted through her like a wave crashing against a high cliff followed immediately by a third. Mark's expert administrations left her weak in the knees and soon she was on her back, legs spread and in the air as her boyfriend continued his onslaught. Minutes passed by and soon, Lily was exhausted panting heavily. Mark was already starting to pull out his cock while keeping her steady and legs spread out in a perfect split.

Lily shook her head pleadingly, "No, Mark... please... not here. Lets get a room first."
