D&D: You beg him to cum in you
From Create Your Own Story
As the little beast reaches his limit, you scream in pleasure, "Cum inside your goddess, Nagul!!! Get me pregnant with your child!!! Fill me with your hot sticky cum!!!"
You feel horny from the thoughts of being knocked up by this kobold, although your magic will prevent you from being impregnated. You're just twisted like that.
The little beast doesn't need more encouragement than that and you start to feel him shoot thick hot liquid into your womb. You moan and your toes curl in ecstasy as you feel so hot on the inside. You feel your vagina expanding as the liquid is pushed inside with no way out, forcing its way back out and feel it spill down the side of your pussy.
The little beast is exhausted and falls asleep on your chest.
You smile wickedly and lick your lips in pleasure. This little beast's cum inside you feels great.
You slowly push the beast out of you and move your fingers to your pussy and watch in amazement the hot liquid pours out.
You get back up and take a few seconds to rest yourself and clean up.
