"Mark... I have a weird favor for you"
Winwin asked in a whisper tone"What is it?"
"I want you to... like.. suck me off, I don't want to masturbate. It feels so much better when someone else gives you pleasure"
"What about the dominants?"
"That's why they get dick sucks, and they love going at it, so it's a win for both, now don't keep me waiting suck me off"
Mark pulled down Sichengs pants and underwear, he grabbed his dick and shoved it inside his mouth, deepthroating it.
He was choking but he was used to all of this, he kept sucking Sicheng off real good. Sicheng without giving mark a warning, started fucking his mouth. Mark kept his head put.
He started bobbing his head faster, he knew Sicheng was close when he felt his dick twitch. So he sucked a bit deeper and slower. Without a warning he let out his sticky load inside of marks mouth, mark being a good boy, swallowed the liquid.
"Such a good boy"
