According to one scandalized wedding guest, fundamentalist Christian wild child Jessa Duggar Seewald didn't wait for the wedding night to bang her new husband Ben. Oh yeah: when she and Ben went to privately share their "first kiss," something sinful allegedly happened.

One "Mary B." alleges on the blog "My Life As a Stay at Home Wife and Mother" that Jessa's sister Jinger accidentally walked in on Jessa and Ben engaged in an "act of lust" in a back room of the wedding church. Mary explains, "Multiple people were discussing that when Jinger opened the door to get Jess for the reception, she immediately closed the door with a look of shock on her face. A big group of the girls were waiting outside the room to walk with her out…and my own daughters saw as well."

Here is Mary's absolutely amazing story from the 1,000-guest Duggar wedding [sic throughout]:

I was very upset when I was told about the incident that was witnessed by [my daughters] when the door to the room [Jessa and Ben] were in was accidently opened. I am not sure why they would not wait for the evening to pray and then consumate God's marriage.

The Lord has blessed them and brought them together. To hear so many people discussing what they inadvertendly walked into was heartbreaking and troubling. Why did this happen? How could this beautiful, joyus day now be forever tainted and destroyed by rumors about what the girls may (or may not have) seen? And if this is true why would they commit such an act in the Lord's home...the same Lord who guided them together. This really made me question Ben's headship and leadership skills. I pray he is not swayed to evil. I pray he acts as strong husband and worship leader to Miss Jessa. I have a terrible, guy feeling. I have tried talking to my husband about this but he has said he will not talk about it until he prays about it and gets an answer from the Lord. This on average takes about 48 hours for him to recieve an answer.

Rumor has it in the fundamentalist Christian community that Jessa, 22, was so hot for Ben that she had to hurry up and get married so she could kiss him. (And do other stuff.) Mary reckons that "Ben needs to be a stronger leader and not allow Jessa to be led away by temptation. ... This responsibily lays on the woman, as it's proven that men have a much harder time."

If the sexy Instagram Jessa posted yesterday is any indication, she is enjoying married life, love, and lust. Caption: "It's great living life with your best friend! @ben_seewald."

Update: Although Radar is sticking by the Jessa church sex scandal story, faith blog Patheos took a longer look at the "My Life As a Stay at Home Wife and Mother" blog and determined it could be a satirical blog. The commenter "Mary B," who relayed the back-of-the-church consummation story, could be in on the joke. I guess we'll never know what the Seewalds did (or didn't) do in the back room of a church on their wedding day.
