You scream as you slide down the spandex and lycra pouch. You spin around 180 degrees and come to rest with your face being slammed into the underside of your brother's scrotum, as the pouch snaps back pinning you upside down. Your shouts are buried between your brother's medicine ball-like nuts. His kinky pubic hairs are like pipe cleaners or tumble weeds. The stench is overwhelming. You gasp for breath, as you kick and flail your arms, you feel the balls pulling up, and the your legs are forced apart as the soft spongy thing between them becomes rigid.
"Oh, great! I'm giving him just what he wanted," you groan as your brother's giant butt hits the seat of the chair. There is a blast of air, and you are on your side breathing hot air in the air pocket in the tenting pouch formed by his growing erection.
You notice that your own penis is rock hard and buried in the base of his brother's giant cock. You laugh, "Oh, great now I've got a morning wood, and no hole to stick it in unless I learn to get turned on by mice." You shake your head, and look up through the red light at your brother's towering cock. "What d'ya know, maybe there is a hole here that my dick will fit in after all."
You upright your self, and begin shimmying up the hot red velvety tree trunk. You may be smaller than your brother's dick -but not by much- but...
"You may be a giant asshole, bro, but I can still screw you," you say as you climb rubbing your swollen cock along the side of the tree trunk cock. You know you're not gay, but this whole scenario is making you super horny.
Just then there's a jolt like an earthquake. You cling tightly with your arms and legs. There is the thunderous sound of an explosion, and moments later you find yourself choking on a warm noxious stench. Your eyes water as you realize that your brother just farted.
"Giant asshole!" you mutter gasping for air. You mean both your brother and his ass hole.
You resume your climb with more determination than before. You're going to make your brother pay.
The penis you're climbing twitches, as your arms and legs stimulate your brother. The mushroom top looms overhead.
Logs press against your body through the spandex pouch. Your giant brother's fingers are palpating you, and his cock. Your eyes widen, as the movement gets faster.
"Oh, no!" you scream. Your whole body is being rubbed raw by friction. Apparently, your climbing on your brother's penis wasn't stimulating enough, so now he's jacking off.
