Chapter 11 - Lines are Drawn to be Crossed

Jason came out of the bathroom with a towel wrapped around his waist, thinking I crossed the line and did the one thing I said I'd never do. Although, that imaginary line had been him lying to himself. That had become clear once Jason was inside Becky and knew he'd always expected it to happen. Of course, he had, why else would he have been pushing Evan so hard toward Deana? One morsel of justification was all Jason needed, and Evan cumming in both of his sister's underwear was enough. You can't smell your sister's pussy while you're beating off and not want to fuck her, and under the right circumstances, Evan would do Deana or Gloria.

Technically, Jason hadn't crossed that line, Becky had dragged him over it, and there was no decision for him to make. The decision-making started that morning. Don't do it again, or do it?

Jason probably hadn't been born with morals, but if he had, they were licked off his balls by that dog. Fear of being caught by his mother had been his only restraint. Where had that fear gone? It had been there when he sat down at the table with his mother. He watched her expression for a sign that she could see his guilt, but she hadn't. That's when Jason realized a guilty conscience had been blurring his vision, and that's why he never noticed his mother's body or paid much attention to her expressions. Fucking Becky had opened Jason's eyes. He remembered the look on his mother's face the time she walked in on him and Becky. Horrified, yes, but not at first. Hadn't she waited until his cock stopped spurting cum before saying anything?

All the times he masturbated, knowing his mother was approaching, yet she never caught him. Jason assumed he had been amazingly lucky. And what about the time his mother forgot to lock the bathroom door? Shock and embarrassment filled him, but his mother had stood there with towels at arm's length, not screaming or demanding he close the door. Had she been trying to tell him something?

"Damn," Jason muttered when he saw Becky's room was still empty. He should have jerked off in the shower. How could his sister not be there the morning after they finally had sex?

The thought made him feel stupid. He couldn't start acting like Becky was his girlfriend, or he'd ruin a great opportunity. What could be better for two horny teenagers than living under the same roof? Jason thought there was one thing, but I'm trying not to think about it.

He walked past his room and went out the back door onto the patio, still wearing a towel. I've never beat off out here during the day, he thought, that might settle me down. His neighbors could see him, but only if they went far enough into their backyard to see around the tall hedges that lined both sides of the patio. They were never home during the day anyway. Thinking about getting caught excited him.

Jason sat down and placed his hands on his lap. He parted his legs enough to feel his dick under the towel. A chain link fence was around their yard, but anybody could walk through the gate by the driveway. It was probably even open. Maybe Becky would come home and catch him?

That thought made Jason's cock grow, but he kept it concealed. The idea of getting caught masturbating was exciting, but actually getting caught by almost anybody other than Becky would simply be humiliating. Even if it were Becky, he'd still be embarrassed. The UPS guy or a kid from the neighborhood could walk back there, too. His dick got stiff, and Jason started to peel back the towel.
