"Primo, I've never done this before," admits the plump one, his eyes wide with a mix of fear and excitement. "Me neither," replies the slim cousin, his voice barely above a whisper. They start slow, their hands trembling as they undress each other, revealing their naked, eager bodies. The lean cousin takes the lead, swallowing his relative's thick cock, gagging slightly at first but soon finding a rhythm. The chubby one reciprocates, his mouth watering at the taste of his cousin's pre-cum, their raw, passionate encounter leaving them both breathless and satisfied.
