Jerk him into the glass

You feel his balls twitch, and you know it's time. You grab the glass next to you and lift it up while you point his cock down into it with your other hand. "Come on, Sam," you encourage him, as you stroke his cock as you can with one hand, "just think of this ending up deep inside of your bitch of an ex!" Sam was already close, and he grabs your head with both hands just as you feel his dick engorge, telling you he is moments away from filling up the glass. He begins to pull your face towards him, but stops as his orgasm begins.

You stare at the cum spewing forth from his dick with an almost maniacal intensity, careful not to get any splatters in your mouth. After a few seconds, Sam is drained, and you stand back up, giddy with excitement over the glass of cum in your hands. You look at it from all angles as if judging the way a good wine swirls around in its glass. Oh, you are going to FUCK. MANDY. UP! Now you just have to find a way to get it inside her...

Your mind is spinning with the possibilities until Sam clears his throat behind you. "That was good and all," he says, "but now I really need to fuck you. Well, not right now, of course." He glances down at the now limp cock dangling before him. "Once the plan is complete," you say. Fuck, you absolutely need to feel that thing inside of you. "Yes, once it's done", Sam affirms, a smile creeping onto his lips. "But for now, why don't you just stay here for the night? I don't know about you, but I'm exhausted."
