The twins, in their shared bed, can't help but notice the growing bulge in each other's pajama pants. The leaner one, with a mischievous glint in his eye, reaches over and grabs his brother's cock, feeling it throb in his hand. His brother, taken aback, tenses up but soon relaxes, enjoying the unexpected pleasure. Their bodies press closer together, their hands exploring each other's chests and abs, their cocks hardening in sync as they share a secret, sexual moment under the covers.
