Big Bang The Orgasmic Dissension

Penny and Leonard wanted alone time, so they offered Sheldon food to discuss him moving out. Sheldon, surprisingly calm, brought up their roommate agreement: if Leonard ever chose a woman over him, Sheldon gets to have sex with her while Leonard watched. Penny agreed. The agreement began with Penny performing fellatio, then she mounted Sheldon, riding him with a lustful passion, reveling in his cock. She loved the feeling, getting on all fours then rolling over, letting Sheldon continue dominating her, while staring into her eyes. Sheldon finished, and left Penny filled with his cream. The whole scene infuriated Leonard; Sheldon claiming he'd been taking revenge for an Amy dream made Leonard even more furious.
