Steve was practically shaking once the vibration ramped up, stimulation all around him, the feel of their hands on him, the sting from his hair. He'd just started trying to rock against Peggy, encouraging her and making sure she knew he was okay, when Bucky told him to still, so he did. He sealed his lips around the base of his dick, looking up through his lashes. There were some tears at the corner of his eyes from a combination of the overstimulation and keeping himself from gagging-but he was in heaven, hands digging in to the other man's thighs.
