TDRL; Fuck and impregnate your friend's wife by way of making bets and wagers while he's away,

"Ride? You mean I have to?" she asked, reluctantly holding herself hinged above your cock as though it was a dildo she'd never tried.

For a moment she felt it tap against her pussy as your excitement and anticipation built.

She lowered herself, feeling her lips separate and her folds begin to spread apart. A large knob began to open up her body. She lowered herself down slowly, retaining a shutter and a moan which welled up within her. She noticed you holding one back, yourself.

"Remember, you've got to follow my every instruction." you reminded her."Just don't cum inside me." she pleaded.
"We'll see..." was your reply. She didn't like the sound of your answer.
"Really???"
"Just do as you're told." you instructed.
"Will you put on a condom, then?"
"Not a chance!" you replied with a smirk, knowing full well you had no intention of pulling out of your friend's wife. This was all part of the deal when she'd agreed to bet double or nothing; a wager she never should have made!

At this time she had only the head inside her and already she felt it splitting her open. Her pussy stretched around the large knob. It was already damaging her once tight skin. She strained to lower herself with no help from you. She was to put herself onto you and begin to ride. That was the instruction; her punishment for losing yet another bet. She'd wagered herself.

Three minutes in and you were panting. She was panting too, looking down at you as she lifted herself and let her body fall down just enough to call it fucking. "You can keep doing that until I tell you to go deeper." you said looking up at her breasts dance in concert with her riding.

She felt you throb and hold a fixed pulsation, watching your abs flex and tighten -very hot, but a sure sign of what was cumming soon. She enjoyed the way you looked and pivoted to make you do it again, then realizing what the pulsation was that she was feeling.

"Tell me when you're going to cum." she reminded you."Oh, don't worry. I will!" you promised, placing your hands gently on her thighs, feeling their flex as she lifted and lowered herself in a rotational movement. Her job right now was to ride and she was doing it well. She watched you flex your abs once more, this time seemingly more intense; more defined -sculpted, like artwork.

-A grunt.
"Are you..?..." she moaned into her question, feeling a strong throb from within her.
"All the way down." you instructed. "Fuck me."

"All the way?" she asked, as if asking if that was a good idea. "I think you're going to cum." she suggested as if it were a warning, suggesting perhaps she sould stop.

Another grunt; held back this time.She sat herself down and rocked her hips. You filled her completely. She felt you begin to throb, but continued her motion.

"Ughh! Keep doing that. Ugh..." was your reply. And so she did. "Careful.." she warned. She felt the pulsations begin and froze! "Hey..! AHh!" She felt warmth.
"Ugghh" came a shuttered voice, now gripping her thighs. "Keep going." you said in short order.

She rocked forward and back reluctantly, feeling you unload into her womb. It was too late. She let her jaw drop in a feeling of tormented pleasure.

That was it. She'd be pregnant now.

She felt you release your pent up pleasure. All the time she'd spent trying to bring you to the edge but not cum, it was now all inside her.
