pregnant wife needs the money

My husband and I have fallen on hard times financially.. he can't support us as a family anymore and I'm pregnant and desperate. Luckily, you heard all about your best mates little problems and have offered him a solution- you'll pay him a load of cash IF you get to fool around with his pregnant wife (me).. it was only supposed to be a handjob and MAYBE a bit of sucking just before you cum.. but with all that money on the table, I just can't say no to full on sex with you! I try to hide how good your big dick feels compared to my husbands but it's so difficult to hold back the moans of pleasure.. even if he is upstairs listening.. and he has no idea that we have secretly agreed to have sex.. or maybe he does? What would he say if he could see you touching my pregnant belly?
