Yes

"Unleash all that cum then Jack" you say

With that Jack moans and you see his cock pulsating. He shoots spurt after spurt deep into Jennie's womb. He's shooting so much cum that soon it starts to overflow out of her pussy and you quickly pull yourself out of his ass and start lapping at the overflowing cum

"Oh god he's still shooting more cum in me... I'm definitely pregnant" Jennie moans in pleasure

After a good minute of cumming Jack finally stops cumming and pulls his cock out of Jennie pussy. You quickly grab the spare strap on and push it inside Jennie so she doesn't loose any cum.
