Theo wasn't sure what to make of Greg's cryptic response to that, but he didnt have time to question it. Greg's hand around his cock had his mind shfting again, it's fractured nature fighting against the physical pleasure to try and make sense of it somehow. "I don't, don't know." he stammered an answer, lifting his hips and moving his legs apart as Greg felt around down there.
"I don't, I, I can't, I don't..." he stammered, because he wasn't quite there, he couldn't remember that time and he didn't know what Greg meant but he couldn't stop the way his body reacted.
