Manny squirmed and convulsed inside Lilith's cavity, using the free space to shift and move to act as a sort of vibrator. He couldn't keep up the act when she was pressing onto him though. He was helpless against her when she was intent on pleasuring him intensely. Eventually it became too much and his manhood exploded into climax. Manny wasn't sure how he was supposed to tell her he was done, but his stillness might be one clue.
