The man continued to thrust into Pepper, enjoying the feeling. He couldn't even get words out anymore, only able to whimper and whine and push into Pepper with his head back against Tony's shoulder. Oh God how he'd even lasted this long with all the teasing was a surprise and he felt himself drawing closer and closer to his climax, especially as his best friend bit him and worked that hot mouth all over his skin between whispering dirty things in his ear...
Then he cried out loudly as he toppled over to the edge, feeling like the breath had been knocked right out of him as he came. Whimpering and moaning and working his hips faster into Pepper he finally stilled, practically falling back limp against Tony, trembling with pleasure. His breathing was harsh as he fought to catch his breath, tilting his head to nuzzle his nose against the curve of Tony's neck, whimpering.
