Watching Scott put on the condom made what was happening extremely real to him. He was about to have sex with his lifelong best friend. He was also realizing that somehow he had become the bottom, though he didn't plan on that being a constant either. If...when or if they had decided to do this again..or maybe even tonight he would try and reverse those roles. Not that Scott needed to know Stiles had a need to keep condoms in his nightstand here either though. He did...because of reasons.
He sucked in a hot breath and held onto it though still tried not to tense once he felt the tip pressing up against his anus. There was a bit of a stretch going from his fingers to his cock, but the feeling was different in a pleasant way. Stiles got lost in that kiss, he needed to feel that comfort as he slid further inside of him. His knees bent and wrapped around Scott and even dared to pull him in closer so that he could get deeper. A groan was muffled out through their lips before broken completely away.
"No..no. Just don't...don't stop." He urged the other to keep going, only proving so when he shoved his lower body up to push him inside again. He had started to breath a little hard, the feeling of his cock was pressing on what felt like a switch in his body that made his entire self shake with delight inside. Kissing him again he groaned into their kiss, his own hand stroking his cock with the same pace that Scott was thrusting inside of him.
He heard those words, they echoed in his mind and he knew he loved his best friend. He had always loved him but was it different now. At the moment it didn't matter. "Fuck....Scott..." He nearly growled at the other and his head tipped back as he spoke. "I love you too....don't stop. Fuck....FUCK ME." He had to groan out his words each one becoming more difficult to say once he'd slipped in deep inside of his ass. His hand on his cock began to pump faster.
